New Aardenburg Imaging fade tests posted

2010-04-06 by pr_roark

Mark has posted the results for the latest batch of fade tests.  These include the 40 Megalux-Hour results for the 3MK carbon and K6 Neutral inks on H Photo Rag.  See http://www.aardenburg-imaging.com/cgi-bin/mrk/_4346c2hvd19kb2NfbGlzdC80

The 100% carbon is still looking very good.

The K6 Neutral sample reached its Conservation Display rating point at 37 MLux hours.  See http://www.aardenburg-imaging.com/documents.html for a link to the PDF that explains this rating.  As I understand it, it's the amount of light exposure the print can take and still look very good to excellent.  37 MLux hours is 18.5 Wilhelm years.  

This is a heck of a database Mark is putting together.

(I wonder how a B&W gelatin silver print would do.)

And at 60 MegaLux, the Piezography Sepia inks are running the strongest of the monochromatic inks with scores still in the 100s. 

We're resubmitting fresh Neutral K6 tests to Mark, because the starting points of the Neutral K6 ink tests that are now at Aardenburg were not "neutral". They were too blue and too red with *ab values as high as 3.70 rather than -0.35 to 0.35, indicative of a chemistry problem we had in 2009, and not representative of Neutral K6 on HPR which is actually Neutral (-0.35 to 0.35 on HPR). Mark is going to keep this set up with an explanation, when he posts the new.

Piezo Carbon Sepia inks are excellent, 100% carbon inks.  100% carbon is the key.

The only thing that is stopping the Carbon Sepia from having overall scores as high as the 1800 3MK is that the Museum K is not doing quite as well as it probably can -- could be random.

Given the sensitivity of the eye to hue changes with B&W, I think the only way to beat the OEMs with respect to fade testing like AaI&A is doing is to use 100% carbon.  The OEMs appear able to get better colors than third party players, and the R&D cost of matching the fade rates (not to mention other characteristics) of color pigments for lots of different papers is probably too high to bother with.  HP, with a billion dollar revenue stream to protect, can simply do things the niche players can't do.  

However, while the OEM systems are doing rather well considering how much color they have in the mix, that color will eventually fade, leaving the carbon.  It's just a matter of time.  Then again there is gas attack that is not being tested for the most part.  So, whenever there is color in the mix, there is an elevated risk of tone (hue) change in the print.  Thus I (clearly) strongly advocate 100% carbon as the viable alternative to the OEMs.

The latest paper of great interest to carbon printers is the Epson Hot Press natural paper.  Its very low delta-b allows the most neutral looking 100% carbon pigment prints on non-OBA paper that I've seen.  I think it is close to a game changer.  See the graph on page 2 of http://www.paulroark.com/BW-Info/Carbon-Print-Tones.pdf

The Neutral K6 starting Lab (a,b) at 50% was (0.7, 2.9).  This is not blue; it's slightly yellowish already.  The Lab A is also already marginally too low.  The start for the 3MK was (1.7, 3.6).   

I really don't think pulling out more magenta is a good idea.  Green is not a good color for B&W.  A better magenta ink would help.  Frankly, I'd use Aardenburg Imaging testing to find a matched pair of color inks -- ones that fade at the same rate on lots of papers.  Mark has, in effect, injected a huge amount of R&D into the field (for those who pay).  It's the best bargain we have available to us. 

It's probably no secret that I recommended a premium B&W set to MIS years ago based on my own testing that showed the green shift we're now seeing in AaI&A testing.  My recommendation was close to what I am suggesting above.  MIS had no interest, but I think the economics can work.

On the other hand, I'm sticking to my primary position -- 100% carbon is where B&W fine art should be.  The other approaches are fine, but the purity and stability (including profiling stability) of having no colors in the mix will have great appeal to purists.  What I'd like to see is some competition to find a better, more neutral carbon pigment.  The existing champ -- Eboni -- is available, of course.  But that just happens to be what I found some years ago.  Maybe there are better ones now.

On the other hand, the existing blended B&W inks from the third party sellers are not bad inks.  They have and will continue to provide very nice B&W prints to lots of people.  Most will never see the green shift that we're trying to deal with here.  After all, none of us has actually had a digital B&W print on our walls for 18 years.

Please remember that not ALL of us view "neutral" as a holy grail. Some of us would prefer very warm inks that so far do not exist.

David,

Warm inks (beyond carbon) are just mixing colored pigments into the cabon
ink.
There is nothing magic about these black and white inksets they are just
carbon + coloured pigments, ideally ones that fade at the same rate.

You can do the equivalent yourself -  at the extreme its called color
printing :)
Epson ABW mode will mix in some color for you. If you want more then just go
full blown color.

A warm, what I think of as low gamut sepia print with a 
Lab B of about 14 is easy with MIS LK (and it's other glossy carbon K4 & UT inks).  That's as far as I've been able to get with the 100% carbon inks I've tested.  The old photo at http://www.paulroark.com/BW-Info/Carbon-Print-Tones.pdf is an example.

The MIS LK and Cone sepia hit about Lab B = 8 on HPR.  Aardenburg Imaging fade tests -- 
http://www.aardenburg-imaging.com/acceleratedagingtests.html -- provide the Lab values for the ink-paper combos tested.

When I look through the old photo books, I see a wide range of image tones.  When I made the sepia toner for the UT2 & 7, I targeted a darker sepia, it could then be mixed down with the MIS carbon.  The sepia toner I made was mostly yellow and magenta -- not very stable.  But I could reach a warmth that had a Lab B of about 25 (for a while).

I think the best current approach to darker sepia tones might be done with one of the orange HP or Epson pigments.  It may need to be combined with another color pigment to hit the values you want.  It one does have to use more than a single color ink, keeping the hue of the inks as close to the target as possible minimizes the wobble in tone as the inks fade and the image moves toward the carbon tone.

I decided the warm LK on glossy paper was a better route.  It's warm enough for me.  I'm curious how all the new types of glossy papers look when printed with the glossy carbon inks.  I think Hahnemuhle makes a non-OBA baryta paper that would be interesting to try with 100% warm carbon.

Maybe carbon nanotube pigments will be warmer yet -- a darker sepia.  I do hope they come down in price enough to start testing them seriously.  What the heck, I might even be willing to use the seconds from the higher tech uses for these products.  If they are successful as part of the solar thin film industry there may be enough inkjet grade nanotube pigments to supply us.

If you can live with the warmth of Sepia, and having absolutely the best longevity is important to you... 

Right now the pure carbon inks with the greatest longevity currently being tested at Aardenburg are PiezoTone Carbon Sepia at 60 megalux and Piezography Sepia K6 at 60 MegaLux - both still in 100s.

However, if longevity is not so critical - and image fidelity is not the most important factor - than why not just print in color and use Epson ABW?

On the other hand something to think about - is whether having the absolute best longevity or the most superior image quality is more important than color...

Seven shades of ink produces a significantly better visual print (though not everyone can see the difference) than using three shades of black that would be used in the ABW color system. Photographers who are really critical about the visual representation of their work will see higher quality in a Piezography K6 or K7 print than they will see in the traditional quad black 4 shaded PiezoTone set, and certainly higher fidelity in shadows, highlights, smoother tone, and higher resolution in drum scans than if they print with three shaded systems or ABW. 

Many people here print with two shades and some with one shade of black so all this is relative to your intentions.

If color is absolutely the most critical issue - and image fidelity comes next, you can always overlay a varnish (matte or gloss) onto a printed work to get the warmth you want. So now if highest possible image fidelity is critical along with color - you can use K7 or K6.  Also, its possible to stain the paper with tea or pigment suspended in water after its printed and dry flat in a print flattener...

There are so many ways to skin a cat. Set your intentions and the criteria:

image fidelity
longevity
color
media
visual impact
evidence of inkjet printer
(add others)

then try and align each with a possibility of what's out there - and that should lead you to the solution through elimination that is correct for your work.


Best regards,

Paul, how do you think this would load in a R1800, even through the single-sheet slot? I know you have a R1800 and wonder if you'd mind trying a sheet of that paper. It's rather heavy, on the other hand it is indeed an Epson printer and my R1800 seems to load better with Epson paper.

Thanks!

My "holy grail" in my darkroom days was a French bromide enlarging paper (no longer available) toned in dilute selenium.  I currently use an R1800 3MK setup with Museo II paper for a "natural white" (slightly warmish) tone.  I really like the 3MK results, but have two questions:

1)	To achieve a truly sepia warm when desired, can I use a 3PK setup in my R1800 along with a suitable baryta type glossy paper?

2)	How do I produce a tone similar to dilute selenium with a minimal use of color pigments?

Thanks

Speaking of print fidelity - based on a completely unscientific approach and merely judging by comments made by people, Piezography prints are in a different league compared to ABW.  I use Piezography Special Edition inks on matte papers, so I can't comment about the glossy inks.

One interesting thing that I noticed is that people normally refer to my ABW prints as "pictures" or "images", but they often use "art" and "three-dimensional art" when they talk about Piezography prints.  The "three-dimensional" comment is actually very common for Piezography prints.

On two separate images, different people asked me if there was a "special effect" or a "trick" that I had used.  One image had a very light gray roof easement on a 250-year old church (it was light golden in real life).  It looked shiny and reflective on the print, just the way it was in real life.  The other image was of a black marble statue reflecting light from the overcast sky.  The shiny polished marble was glistening, almost glowing on the image.  Both of these were printed on matte papers!

Jon, I would add another criterion to your list: plug & play vs. tinker.  If one's primary goal is to concentrate on producing high-fidelity images being assured that the inks will deliver to one's vision, Piezography is a great choice – it is plug & play, it allows you to get great prints right after installation.  You don't need to spend countless time, ink and paper to achieve your goals.  I don't have anything against tinkering in general; it's just a matter of personal preference.

The Epson Hot Press Natural using Eboni Black Only in an Epson 1400 is about dead neutral.  The 50% Lab B is less than one unit above the paper base Lab B.

Here is a QTR profile for the 1400 Epson Hot Press Eboni Black Only:

> Paul, how do you think this would load in a R1800, even through the single-sheet slot? 

I just tried to feed a piece in through the normal paper feed slot, using the paper feed button, and it fed fine (with a slight hand assist).

I think with the 1800 3MK, it'll be a terrific paper.

That should work.  You'll have to so some profiling.  I'd guess following the instructions in the notes of the Dmax test and Start profiles will work with a 3PK setup.  Of course, be sure to re-set the ink positions used.

> 2)	How do I produce a tone similar to dilute selenium with a minimal use of color pigments?

Sprinkle a little LM onto the paper.  Define it as a tone in QTR and have a very low ink limit.

well because it sucks. I can get away with that, perhaps the backlash for you would be too great if you don't maintain a more civilized voice and stance, so thanks for helping to promote generous discourse in this community. 
But I'm sorry, I don't want fine B&W printing to go backwards. I've argued and illustrated the superiority of the multi black systems I have access to, and compared the silver contact print, many times over the years to ABW.

Add to that the visual impact differences. Now many don't see it, or if they do- don't care. Interestingly, often the people who are sensitive to it are those with a strong background in pre-digital fine print. Often people who don't care are new enthusiasts dslr, for whom good B&W was not even possible before ABW, so it is a revelation. We all welcome new photographers, but should they be who set the standards? Are we only trying to supply reasonable solutions to them?

I don't expect them to use my setup. In fact, I'm somewhat jealous they have a readily available out of the box solution that makes them happy.
I have old 3000 quad tone prints here I'd take over ABW, in a heartbeat. If it managed to force all other alternatives from the market, I'd make digital negs for platinum or head back to the darkroom. Oh wait, those solutions were crowded out of the marketplace as well. Guess what? ABW and many other "solutions" provided us now are not even as good as the old darkroom by some standards.
Longevity has always been extremely important in photography, and historically one of the greatest scientific challenges. But what's the point of prints that last forever, that fall behind artistically?
Thanks to everyone here working hard to develop systems that result in beautiful print, and/or promote longevity, hopefully we'll get it all, and make prints exceeding the photographic masterful quality of systems 100 years old.

Paul,
Thanks for mentioning BO printing with an E-1400. Reading this tread I was beginning to question the wisdom of using such a system :)

BTW, I'm now finishing off a box of Piezography 300gr Museum Bright White 13x19" paper that I bought a long time ago. Nice paper with just the right amount of surface texture; too bad it disappeared not long after I purchased it. With MIS Ebony it makes for neutral prints:  (Don't see any blue or brownish tint). After the first 10 sheets, there were some paper feed problems, even if I hand-guided the paper.

Cheers,
Andre

Well, BO works for some and not others.  I personally use it in the 1400 for my brochures with HP Z3100 PK, and it works very well for that. 

Similarly, ABW works for some and not others.  I, personally, prefer more carbon inks and no colors, but this does limit the flexibility of the inkset.

Frankly, since the days of UT2 and the other variable tone inksets I designed and used, I think there has been something of a convergence of approaches between what I do and the Cone camp does.  I have moved away from the more flexible variable tone inksets for my personal use.  In my old 7500 I ended up with a single monotone inkset - Eboni-6.  Now, in my 7800, I've moved to a system where there are basically 2 monotone inksets in the machine -- Eboni and its dilutions, as well as the warmer (sepia on glossy) MIS carbon.  I think you'll find that a number of the Piezo users have a similar setup with, in effect, 2 monotone inksets in their wide format printers.

I prefer to not have any high gamut inks in the mix, and I think the quality of what I'm getting from the wide format printers has increased with the move away from high gamut inks.  I'm using and encouraging 100% carbon for longevity, but not at the expense of having as many gray, very low gamut inks as needed for top quality.  

With the 1400, I would not be surprised if I end up printing my fine art prints with a blend of 2 profiles -- one black only and one "Eboni/Carbon-6" (currently with only 4 Eboni-base inks).

Hear, hear!

ABW is about lowest common denominator printing. Good enough isn't what 
I'm after. I want to eclipse the techniques that came before. ABW isn't 
the path to that goal. Not even close.

  well because it sucks. I can get away with that, perhaps the backlash for you would be too great if you don't maintain a more civilized voice and stance, so thanks for helping to promote generous discourse in this community. 
  But I'm sorry, I don't want fine B&W printing to go backwards. I've argued and illustrated the superiority of the multi black systems I have access to, and compared the silver contact print, many times over the years to ABW. But that's just the technical stuff, I have to add that criteria for masterful photography has always had a technical element, it can't be helped, the process includes science. Add to that the visual impact differences. Now many don't see it, or if they do- don't care. Interestingly, often the people who are sensitive to it are those with a strong background in pre-digital fine print. Often people who don't care are new enthusiasts dslr, for whom good B&W was not even possible before ABW, so it is a revelation. We all welcome new photographers, but should they be who set the standards? Are we only trying to supply reasonable solutions to them?
  The variety of criteria, and expectations, are huge, why must any of us comply with another's? Why because one person argues to me ABW is outstanding I'm supposed to accept that? I don't expect them to use my setup. In fact, I'm somewhat jealous they have a readily available out of the box solution that makes them happy.
  I have old 3000 quad tone prints here I'd take over ABW, in a heartbeat. If it managed to force all other alternatives from the market, I'd make digital negs for platinum or head back to the darkroom. Oh wait, those solutions were crowded out of the marketplace as well. Guess what? ABW and many other "solutions" provided us now are not even as good as the old darkroom by some standards.
  Longevity has always been extremely important in photography, and historically one of the greatest scientific challenges. But what's the point of prints that last forever, that fall behind artistically?
  Thanks to everyone here working hard to develop systems that result in beautiful print, and/or promote longevity, hopefully we'll get it all, and make prints exceeding the photographic masterful quality of systems 100 years old.
  End of incoherent rant...

George, I have a solution/idea for you that would be quite the upgrade to what you're doing now.

I lost my internet connection last night, so I had some time to think about a Piezography system for your needs. But, I was a little surprised to learn that 3MK is a black ink only system. I thought it was the MIS version of Epson ABW and that it used three shades of black. I read its specs and its definitely a black ink only system, albeit with three locations in which to put 100% black ink. This explains the ease at which its longevity testing is going. It is much more difficult naturally, to get longevity out of six and seven shades of black ink. But, that's neither here nor there when you're seeking very specific aesthetics. Even though we can easily fit Piezography K7 Sepia to your printer for killer longevity, your needs do not make you a candidate for carbon only printing.

In the meantime, you are seeking to make a typical selenium toned print and a typical azo type print in your Epson R1800. This would be my advice to you. If you are serious about the image-quality of your black & white printmaking, then you should be using dilutions of black that have been partitioned in order to divide a grayscale image into a much greater amount of gray values than you can realize by using black ink only. That is not an opinion, but a fact. You should use at minimum four shades of black (that's opinion). Piezographers typically use six and seven. The results are not just additional gray values but a depth to the quality of light that reflects back from my pigment. There would be zero metamerism if that is important to you. The concept of Piezography is not to imitate the darkroom, but to exceed it, as it carries its values and traditions forward in a digital era.

In an R1800 printer I would suggest using:

Piezography K7 shade 1 Matte Black
Piezography Warm Neutral shade 2/3 (50%50%)
Piezography Warm Neutral shade 4
Piezography Warm Neutral shade 5
Piezography Selenium Shade 2/3 (50%50%)
Piezography Selenium Shade 4
Piezography Selenium Shade 5

The Warm Neutral inks can give that straight azo look (slightly greenish warm tone) - and of course Selenium inks were designed in collaboration with my teacher Arnold Gassan to imitate short-bath selenium toning. These are what you're seeking.

This is a dual quad system and you would be in monochromatic nirvana being able to blend two curves together, or split tone between the two. You could add a little Warm Neutral curve to the Selenium curve and visa versa in highlights, midtones and shadows, or simply use one or the other. My pigment is so finely ground, that paper choice is how we do the variable tone in Piezography. So the possibilities without reverting to color inks might be limitless.

I have a system like the above running in my R2400 which I love for my own work. I do some wicked split toning using the three positions of the two curves blending - allowing mixes independently in shadows, midtones and highlights. We printed a number of portfolios for clients using this system to replace a dual quad StudioPrint system we had. We replaced it because I get significantly better shadow and highlight detail with the Piezography profiler than I can with the StudioPrint profiler.

George - if you would like to see your work printed on such a system - and if you can supply me with darkroom examples of what you once loved - write me off list and I will arrange a debut for you. Will allow me to pick out the best paper and curve blending for you. If you love it - you can then upgrade. 

Actually, this would be a significant upgrade to anyone using black ink only here - or who is using three shades of black as is found in Epson ABW or the MIS UltraTone system. 

Piezography is like the audiophile of photography, choosing image fidelity over the convenience of using color inks. It will realize much more depth and detail than you can achieve in silver or palladium.

If you need a matte/glossy system - you do have an "eighth" unused slot in my system suggestion.  I could flesh this matte only system out in just a few weeks and provide Roy with a media curves update for QTR. Would encourage me to do so on the 1800, 1900, 2200, 2400, 2880s if others were inclined to upgrade...  hint hint!  The matte/gloss would take a few weeks longer to develop.

2010-04-08 by piezobw

Tyler,

I'll rant with you!  lol  You are of course right.  The two issues are really convenience and "good enough".  I have never been shy to be shot down in flames on this users list. Although I admit I gave up on this list somewhere back a few years ago - and probably as a result of that, it is reverting backwards to printing with black ink only again. I should have been more thick skinned I suppose...lol. o'well

So, at SPE I reviewed a portfolio by a photographer that was marvelous. She shoots people who are shooting with cell phone cameras. The photography was incredible. Really unique. I loved it perhaps even the more because I happen to like shooting with cell phone cameras. I believe they are culturally important in a visual context. Anyway - she printed it with ABW on a baryta paper and the difference between ink and paper was distracting. It stopped me because it looked like ink sitting on paper, and it interfered with my ability to see the work. And it reminded me of a stern lecture I received in college from my lithography teacher who said my first prints looked like I had shi**ed the ink onto the paper. He said lithography should be the marriage of ink to paper and that statement has always been a strong influence on my development work in ink making as well as printmaking. I've printed editions since the 1970s for artists that I believe are marriages of ink to paper. Beauty first!

In terms of longevity - I should be touting my Carbon PiezoTones and Sepia K6/K7 inks all over my websites and marketing - but I also agree that longevity is not everything - and therefore neither is carbon everything. And I don't really mention the Carbon inks as anything other than an aesthetic choice.

Anselm Keifer, DeKooning, Rauschenberg, Cindy Sherman just to name a few - along with Leonardo DiVinci have all used extremely fugitive materials in their art making that has not seemed to curb their careers nor influence.

My belief, and I may be shot down as a result of saying it, is that digital printmakers feel inferior still to traditional printmakers - and therefore jump on longevity as if its some way in which to attain the same level. That type of thinking is wrong in my opinion. If you set your sights on some level, you will never exceed it, and you will always be a slave to trying to attain the same level of something that you feel inferior to. This has plagued digital fine art printmaking for as long as I have been involved with it - which is 27 years. But, it is not something I have ever allowed myself to be swept up into.

I watched in the mid-1990s as some group tried to set "standards" for fine art digital printmakers - these same standards prejudiced against the most important and influential artists of the day - like Hockney who was doing some early digital work - and certainly against many of the editions I had been producing since the mid-1980s. It fell apart under its own weight. I affectionately referred to it as the International Association of Digital Fine Art Police.  They called themselves the International Association of Digital Fine Art Printmakers. I was asked to run for President.  icccckkkkkk!   I ran away from this group as fast as I could because it seemed like the anti-christ of fine art.

You can not put "fine art" into a set of parenthesis - ever. It only backfires on your intentions of promoting it. Fine art can be fugitive. Hockney said it best when he said something like what is the use of art that will last forever if it doesn't look particularly good.  or to that effect. You echoed it yourself. It really is a universal thought uttered by artists since they began working with material other than stone.

Is Cindy Sherman irrelevant because she likes C-Print? She gets $100,000 a photo that has a short chemical life. C-Print has a very certain look that some photographers prefer over more archival or/and fade-resistant alternatives. If art is important enough to preserve, someone will. But I would hate to see all of my customers only using my Carbon Sepia or my Sepia inks. It would be a terrible waste of creativity. I'm not opposed to making prints that will outlast the papers they are printed on as a practice - but I also do not want to see artists and photographers having to fit into a pre-determined set of aesthetics, or feel that they are not in some "club".  Digital printmakers do this to themselves over and over again. It's like we never learn - yet the day of digital is not tomorrow coming - its yesterday already. It's more than arrived.

We here are for all practical purposes the last vestige of material photography. Even inkjet one day, will be cast aside because of the pollution paper making causes. It will all end up one day on the big screens. B&W will eventually be a subset of color. Epson will be Kodak. They protect their LCD technology to such a point that they have been fined multi-millions by our own Gov't for market interference. Photography is temporal at this point. It should be made beautiful and it should be made to last without eating itself up in chemical deterioration. This is longevity vs archivability.  Roarke is correct in wanting to use papers that do not have inkjet coatings if his concern is to print on papers that will last as long as possible. But as one carbon supplier to a carbon promoter, if you print images of significant importance - history will preserve the work. It does it for you, so you need to concentrate on what it is you have to communicate. Even the Mona Lisa is fragile. DeKoonings often burst in sunlight because of his tendency to favor Joy dishwashing liquid as a paint medium. Art is imperfect. That is what makes it so ideal in a world which is often not.

My rant for today is if you can't make it as beautiful as possible, why make it?

Sometimes on the weekend. I leave my laptop at work for a taste of life...no email...no surfing...no MotoGP updates....just nature. My cell phone does not work in our rural location. We do not have TV...

We're in early Spring - the earliest on record in Vermont and I have been enjoying the weekends here outdoors. Life without internet can be intoxicating.

I know this will sound weird...but we recently found a skid of 100 rolls of Piezography Museum Bright White 44" paper that had gone missing at our shipping fulfillment house. I should say that they found it. It is like losing an elephant for about seven years. 

The paper is available to those who liked it, but only in 44" format. The paper mill that made this paper for us is long gone out of business...

Write me off list for a price...

Well, BO works for some and not others. I personally use it in the 1400 for
my brochures with HP Z3100 PK, and it works very well for that. 

Similarly, ABW works for some and not others. I, personally, prefer more
carbon inks and no colors, but this does limit the flexibility of the
inkset.

Frankly, since the days of UT2 and the other variable tone inksets I
designed and used, I think there has been something of a convergence of
approaches between what I do and the Cone camp does. I have moved away from
the more flexible variable tone inksets for my personal use. In my old 7500
I ended up with a single monotone inkset - Eboni-6. Now, in my 7800, I've
moved to a system where there are basically 2 monotone inksets in the
machine -- Eboni and its dilutions, as well as the warmer (sepia on glossy)
MIS carbon. I think you'll find that a number of the Piezo users have a
similar setup with, in effect, 2 monotone inksets in their wide format
printers.

I prefer to not have any high gamut inks in the mix, and I think the quality
of what I'm getting from the wide format printers has increased with the
move away from high gamut inks. I'm using and encouraging 100% carbon for
longevity, but not at the expense of having as many gray, very low gamut
inks as needed for top quality. 

With the 1400, I would not be surprised if I end up printing my fine art
prints with a blend of 2 profiles -- one black only and one "Eboni/Carbon-6"
(currently with only 4 Eboni-base inks).

Today must be a one for rants; here's my humble contribution.

All forms of inkjet printing have their advantages and disadvantages, all of them. It is the the user's prerogative and duty to balance and make choices based on needs and aesthetics.

No matter how much the 3K + color systems get knocked around, they are the MOST versatile solution in the marketplace today: (1) they can be used with virtually all papers, both matte and glossy, (2) can be tailored to create the widest range of hues, and all sorts of split-tones, (3) they are fairly light-stable (but not the best, when significant color is used), and (4) they are much better than "good enough". With all due respect, you do not offer all of these attributes in a single inkset - period. When vesatility is most important, K3 +color are actually the BEST solution, not just good enough. And when image intergrity (what is the definition of this fuzzy jargon anyway?) is considered, it is downright disingeneous to say that this technology fails. I know it does not. I have printed with all sorts inks, ranging from black only (BO), to full color, to K2 (alone and +color), K3 (alone and +color), custom mixed K6 (no color). I found that every refinement produced some improvements, and some drawbacks.

These prints you mention seeing at SPE; well whoever did the printing was not skilled at using the tools at their disposal. They did not make the right choice between paper, inks, and ABW RIP control. That is NOT how you judge a technology. There is no guarantee that if she was to print, say using MPS Selenium, that magically her prints would improve. If fact, if she had wanted the prints to by on a glossy baryta stock (her prerogative), with a particular hue (her prerogative), most likely using MPS Selenium would make the prints worse! The inks would still be sitting on the surface and she would have lost all control of hue.

That brings to mind a recent experience where limitation is marketed as a positive attribute. Apparently they don't make mattresses like they used to. When shopping for a new one, I was told that that the new ones are "no flip." I thought "huh?" Obviously the makers are saving money in manufacture by makeing only one surface sleepable. Perhaps they pass the savings along to the buyer, but I doubt that. So they market it as "they don't need to be flipped", rather than the truth that "they CANNOT be flipped." In the same vein, the K6/7 Neutral are marketed that you can control print hue through selection of paper. Well the truth is that the "neutral" look of K6/7 inks is LIMITED to a very narrow range of papers. If you want the same look with another set of papers (very valid need), you have no choice but to go around the limitation of this inkset. Where do you turn? One very viable and better than "good enough" option is Epson OEM K3 inkset with ABW or QTR. So there is so much BS about limitations and attributes in marketing.

Speaking of aesthetics: Black only BO prints (single or multi-channel) have an aesthetic that absolutely cannot be duplicated by any other system. This look is not for everybody, or for every image. But I can attest that certain images absolutely sing with this method. In comparison, the same image with my fully linear, ultimately smooth custom K6 inks are opaque and blah. I still (ocassionally) turn to this archaic method even when I have so many other newer options avilable to me. Tyler wrote that if his current preferences were not available he would turn to Platinum printing with digital negatives. Well, how much more archaic and backward can you get? If subject to 10X or more magification, his revertion to this technology would be objectively, measurably inferior to say a contact print on silver gelatin paper. But so what? If he likes the look, that is all that matters. So why the derision of BO prints? By your punditry, you guys are doing a disservice to the potential of a perfectly viable option.

When someone explores inkjet b/w printing for the first time, tries ABW, and is dissatisfied with results, they often turn here for answers. It is rare that they receive the advice to look at their current workflow, refine their images, learn to use ABW or color driver properly. Guess what, if they cannot get good results with ABW, they do not have enough slills to go to more complex (and expensive, finicky, frustrating) solutions yet. Because ABW is capable of producing outstanding results in the right hands. Outside of making a buck, you guys are the gurus, teachers of printmaking, and so it is your duty to fairly deliniate both pros and cons of your prefered technologies. So, please let us not stoop to the "no flip" matteress saleman pitch.

Rant over. Respectfully,

Shilesh

I loved it perhaps even the more because I happen to like shooting with cell phone cameras. I believe they are culturally important in a visual context. Anyway - she printed it with ABW on a baryta paper and the difference between ink and paper was distracting. It stopped me because it looked like ink sitting on paper, and it interfered with my ability to see the work. And it reminded me of a stern lecture I received in college from my lithography teacher who said my first prints looked like I had shi**ed the ink onto the paper. He said lithography should be the marriage of ink to paper and that statement has always been a strong influence on my development work in ink making as well as printmaking. I've printed editions since the 1970s for artists that I believe are marriages of ink to paper. Beauty first!

That type of thinking is wrong in my opinion. If you set your sights on some level, you will never exceed it, and you will always be a slave to trying to attain the same level of something that you feel inferior to. This has plagued digital fine art printmaking for as long as I have been involved with it - which is 27 years. But, it is not something I have ever allowed myself to be swept up into.

It fell apart under its own weight. I affectionately referred to it as the International Association of Digital Fine Art Police.  They called themselves the International Association of Digital Fine Art Printmakers. I was asked to run for President.  icccckkkkkk!   I ran away from this group as fast as I could because it seemed like the anti-christ of fine art.

It really is a universal thought uttered by artists since they began working with material other than stone.

C-Print has a very certain look that some photographers prefer over more archival or/and fade-resistant alternatives. If art is important enough to preserve, someone will. But I would hate to see all of my customers only using my Carbon Sepia or my Sepia inks. It would be a terrible waste of creativity. I'm not opposed to making prints that will outlast the papers they are printed on as a practice - but I also do not want to see artists and photographers having to fit into a pre-determined set of aesthetics, or feel that they are not in some "club".  Digital printmakers do this to themselves over and over again. It's like we never learn - yet the day of digital is not tomorrow coming - its yesterday already. It's more than arrived.

> We here are for all practical purposes the last vestige of material photography. Even inkjet one day, will be cast aside because of the pollution paper making causes. It will all end up one day on the big screens. B&W will eventually be a subset of color. Epson will be Kodak. They protect their LCD technology to such a point that they have been fined multi-millions by our own Gov't for market interference. Photography is temporal at this point. It should be made beautiful and it should be made to last without eating itself up in chemical deterioration. This is longevity vs archivability.  Roarke is correct in wanting to use papers that do not have inkjet coatings if his concern is to print on papers that will last as long as possible. But as one carbon supplier to a carbon promoter, if you print images of significant importance - history will preserve the work. It does it for you, so you need to concentrate on what it is you have to communicate. Even the Mona Lisa is fragile. DeKoonings often burst in sunlight because of his tendency to favor Joy dishwashing liquid as a paint medium. Art is imperfect. That is what makes it so ideal in a world which is often not.

I've argued and illustrated the superiority of the multi black systems I have access to, and compared the silver contact print, many times over the years to ABW.

The HP Z3100/3200 PK and gray inks are very lightfast and stable according to the Aardenburg Imaging  and Wilhelm tests.  I will continue to use the HP PK in my 1400.  There is no other blended color+carbon ink that I recommend if longevity is a serious factor.  Still, however, the total delta-e of the HP 50% neutral test patch at 40 MLux-Hr in AaI testing was more than twice the Eboni 3MK or Cone Carbon sepia 50% test patches.

(Note that my limited experience with Canon ink suggested to me the color was not appropriate.  I don't know much about it otherwise.)

Shilesh,

I don't disagree with you about much what you ranted, and ranting is healthy. It opens up discussion about things that are truly important and thought provoking. It's a philosophical difference between us though, don't you think? 

I agree that using color inks is forward thinking and lamenting the loss of traditional photographic values is backwards thinking. But, I've been making digital b&w prints now for nearly three decades and I've seen it all, and started or have done most of it - and nothing new has yet inspired me to adopt it in my own work or that which I do for others. I can't be the one who teaches how to deal with the limitations in ABW, nor its pros and cons. That has to be someone else like yourself. Because for me, ABW exists as a technology which I can easily still exceed.

So, the discussion is not so much a commercial argument as to what system is better or worse, but a philosophical argument that is at the core of light and how we capture it and then how we choose to display it back to the eyes of the viewer, and probably what we are willing to compromise in order to do so for the sake of convenience (maybe even expense). 

I have to agree with Tyler in regards to lamenting the loss of what silver and platinum can do that Epson ABW and color inks can not do (as well). Yes, I agree with you that its totally backwards thinking - but only because black & white photography basically is extinct...in that it is like the last lumbering and weak dinosaurs on a planet that can no longer support them. They will continue maybe a few more generations at best, but will not be able to keep up with the mammals who need less food and can hide better from the elements. And without the dinosaurs being gone, humans would not have succeeded to invent photography! So perhaps it is a necessary thing. A good thing? No. A more convenient thing? Not for me either.

On the other hand, I make photographic printmaking systems and will continue to makes them the only way I know how to, which is to exceed what is available because that is one of the primary motivations for me as a printmaker. When a system comes out that is as good as or better than what I can imagine - I will simply stop. My candle if its not bright enough will no longer have a purpose as developer. I have plenty other passions which I do - and I will not unnecessarily hang onto development when I can still collaborate and continue my own photography and printmaking. My color ink business is far exceeding the business I generate with Piezography. But color ink is not close to my heart in the same way as b&w is.

I have been making monochromatic ink as far back as 1977 because inventiveness is next to printmaking. I have been developing printmaking techniques since founding Cone Editions in 1980. If I had my way, all digital printmakers would work on inks and software and behave like traditional printmakers do - so that the medium as a whole would evolve rather than depend upon the OEM. 

This is a new notion...not inventiveness being a new notion...rather it is a new notion to be a printmaker using existing technologies without the ability to modify them. That is a modern notion whether in the darkroom or print studio. And frankly, that is what is backwards. Skill is not a modifying tool as you regard. Making ink and software are modifying tools. Paul Roarke has it. Roy Harrington has it. Dozens of others who attempt to mix and blend and find their own way in it have it. You even mentioned that you have tried some experimenting in this regard. But, we're all up against the limitations imposed by patent technologies. Improving our Photoshop skills and fooling printer drivers or operating systems is not a way to evolve printmaking.

Neither lithography, etching, woodcut, intaglio, nor silkscreen would have evolved if printmakers had accepted the status quo. All of these new printmaking inventions evolved out of discovering ways to modify and exceed the capability of the commercial version from which it developed. The history of photography has been similar. We all know that. 

This is nearly the first time in the history of photography and printmaking that such a large audience has been held captive by the OEM because of the barrier imposed by technology. This is the first technology with limitations built-in that the average user and student can not exceed it, nor experiment with it, because of disabling patents, or the inability of a photographer or printmaker to understand software and ink making.

Yet, when you read the messages on this board, what you read is photographers struggling to recapture something lost that is familiar to them in a visual context. They are adapting - some successfully and others not so successfully - to what they used to manage with ease and particular skill associated with experimentation and exploration in the darkroom. Many had produced autographic systems of their own which they are finding impossible to do now.

So these are important philosophical differences rather than being arguments or salesmanship - and more people are affected by it than I think you realize. I may be closer to those who struggle because they find their way to me. Piezography is decidedly retro I admit. But, it takes tremendous technology in order to be so - and that makes it forward. Exceeding the status quo is always forward thinking even when one is trying to preserve the past like I am. 

In any event there is more than enough room for everyone to do whatever it is they wish to do with these printers. Everyone probably has enough to worry about just keeping print heads moist or figuring out how to upgrade to MacOSX or the latest Windows without undoing everything that they struggled to get (or almost get) right where they wanted (or almost wanted.)  ;)

Where can I find a reference source that expands on this? I had already come to the conclusion on my own that inkjet coatings could be a problem just because the manufacturers don't talk about them and are reluctant to tell you what's in them (one just flatly refused to provide an MSDS which is a Federal no-no), but I would like to know why these coatings are a potential problem.

Also...

On a semi-related topic: I have seen "Wilhelm years" mentioned here several times and could use a reference to an explanation. Apparently Wilhelm's tests are being "translated" into some other number that in some cases seems to imply that prints are virtually turning to dust as they issue from the printer <grin>. Anyway, it makes it difficult to compare the numbers for some of the B&W ink sets discussed here to Wilhelm's numbers for OEM inks. The implication that Wilhelm's results are overly optimistic leaves me with no point of reference.

2010-04-08 by shileshjani

Jon,

Good thoughts here. If you feel the brunt of my rant, my apologies. The rant would have been equally well-directed at any number of other highly opnionated persons in this forum. I would be perfectly happy to sit down over beer (my treat), preferably poring over prints, rather than this impersonal (and anonymous) forum. Perhaps next time I am in the Vermonts area.....

The point I am trying to make is please be respective of other, viable options. These may not be your choice, but that does not make them universally wrong or inferior. I participate in a monthly exchange of prints, so get to see lots of prints by others. Not everyone in the exchange is highly skilled, but neither is everyone a slouch at printmaking. Some in fact have refined their crafts to a very high degree and are customarily making their own ink mixes. They actually take the potential of inkjet printing to a level higher than anything available commercially (sorry, but higher level than K6/7 in limited attributes). But most use straight-up ABW, and some use linearized ABW. Many have used various flavors of K6/7. These are my objective observations: 

Generally prints made with K6/7 systems are no better than those made with ABW. Ultimately it is the skill of the printmaker that dictates the quality of the final result, not the tools they used. I am near-sighted, and routinely take my glasses off to view prints nose-to-paper. When I use my view camera, I don't even use a loope for final focus, just take my glasses off, and go nose-to-ground glass. So I know what smoothness is. Never have I sensed that K6/K7 trumps ABW. Under high magnification, sure there is a difference, but it is totally meaningless, and what I call politely "technical self-gratification." So naturally, I ask myself what is all the hubub for K6/K7? I read someone (you or Tyler, or perhaps someone else)recently write something to the effect that the visual superiority, fidelity of K6/7 is not something everyone can see. When I read that, by knee-jerk (and quite possibly totally accurate) read on that was "very few people, or more likely no one will see that difference unless they use a loope." So why bother? Well, you bother because there are cons to ABW, especially selective color fading. So use pre-mixed mono inks. But that comes with a price; you are now stuck with the hue you get with the paper of your choice. No free lunch. In some of your recent post, I have seen a decided view of a balanced approach to selecting the ink choice based on important criteria - that is good to see.

I personally have no angst about or yearning for the long-gone past; I never practiced darkroom printing, other than printing electron microscope images. So that technology has no emotional meaning to me. I have also participated in LF print exchanges, where contact prints from 8x10 negatives were submitted. Total blah. Not because of the technique, rather because of the photographic and printmaking skills of the authors were limited. It being a contact print on 8x10 Azo has no aesthetic appeal in itself. On the other hand, BO prints made by someone with skills of say Clayton Jones or Nicholas Hartmann were tremenndous. Again, not because they were BO prints, but because these guys knew how best to use the technique. Speaking of Clayton Jones, me maintains a perfectly grounded-in-reality database of papers, Dmax, paper color, print hue, all out of goodness of heart. Why not do the same for Piezo inks?

Some of us have become wary of e-marketing lately, and are naturally skeptical. So we do our own research (waste time). Like the discussion we had a few days back about encapsulation vs resination. I come from a technical background, and have bona-fides in materials science/engineering and low-and-behold have done a lot of electron micrscopy of sub-micron particles. See links below. You would need subscription to access other peer-reviewed articles.

http://www.ors.org/web/Transactions/48/0132.PDF

http://www.ors.org/web/Transactions/48/0049.PDF

So when you wrote that you have never looked at ink particles at EM level of detail, I just about fell out of my chair. I was asking "if so, how can Jon claim that each and every pigment is (triple) encapsulated." Really Jon, how do you know that? But, I stopped myself from asking because ironically it does not matter that they are triple or otherwise encapsulated. What matters is the resultant print on paper. There, I have already seen with my eyes that it does not matter at all. Clogging and clumping? I don't know, but I may have to scratch that itch, and see for myself under an EM. My point: please keep the discussion to what is relevant, and truly verified with data. I was surprised that even HP had nothing more tha a schematic of encapulated pigment, not an actual EM image.

OK. This has gotten long enough. I must tend to my daughter's needs. But as a final word, if the large corporations are putting barriers, beat them by being more inventive, more innovative; that is the American way.

Respectfully,

Shilesh

David,

I think the biggest and most misleading factor is the word "archival" misapplied to "fade resistance" when describing papers and inks. These are two mutually exclusive terms. One having nothing to do with the other. People pick and choose papers without thinking twice which might be a more archival solution than the other. Everyone is wrapped up in ink longevity without realizing the results do not take into account anything other than the ability of the paper to retain its whiteness during the endurance of the light stability testing but do not take into account the ability of the paper to last over time.

For example, IRIS dye based prints on uncoated Somerset Satin paper are very archival - but they can fade very quickly. They have a low light stability rating of a few years but can outlast chemical photographic processes when kept in archival storage conditions which include limited exhibition. A much more fade resistant chemical print will not outlast an IRIS dye based print on uncoated Somerset in archival storage conditions. Epson Ultrachrome inks on newspaper printing paper is not archival, but could test in Wilhelm conditions to be very, very fade resistant - perhaps centuries as a rating - while the paper will deteriorate in practicality within a few years. On the other hand, Aardenburg light stability testing will pick up the quick discoloration of the newsprint where WIR testing would not. I hope I drew two comparisons that make sense in regards to fade resistance and archival, so that you can separate them because they are at the heart of paper selection and coatings.

Ideally, an uncoated paper, and an unsized paper (with the exception of starch sizing) would be ideal and the only papers that seem to retain enough ink to be acceptable are japanese fiber based papers - but they are very "buff" and very thin. The dMax is lower than most would appreciate. I print on a lot of uncoated japanese fiber papers and I also print on uncoated japanese kozo/cotton blends by using heated printers to warm the paper and allow greater dMax through evaporating the inks quickly. But, its not the cup of tea that many photographers would appreciate. 

The reason for using these is not fading of the inks, but historical longevity of the actual object. Plus some of my clients really love japanese handmade papers and the way ink reacts with it. This type of paper used in printmaking has existed for centuries already and the paper has been designed to last centuries by papermakers who pass on the skill in generations of families making for all practical purposes the same sheet, from the same spring water, and the same raw grasses for centuries. Putting a typical inkjet coating on it - changes the game. Now it becomes the coating rather than the paper that we must rely on to not absorb pollution at a higher rate (which is what a coating in effect is designed to do.)

Western papermaking in terms of uncoated materials also has a long history - but not nearly as long as japanese paper making. But for inkjet - we need coatings. What these coatings do is to absorb moisture (ink)  but unfortunately will continue to absorb over time and therein lies the 300lb gorilla. Is it better or worse than gelatine? Check back in a few more decades...You will need to however, rely on conservators not light stability testing to learn about coatings and their archival life. Two different subjects that you really need to wrap your head around. The MOMA and the Met have conservation departments that are accessible and you can visit to ask questions about media and the atmosphere in order to understand what you need to protect against. So little is published on this subject as it pertains to ink jet other than its propensity to absorb OZONE. The making of an inkjet coating, if that is what you are involved in might look back historically to the use of starch and gelatine rather than some of the more inkjet oriented materials.



Wilhelm and Aardenburgh have some specific differences which you can read about in their own words as it pertains to the differences in their light stability methods.

You can go read about Wilhelm's testing procedures directly on WIR website as it relates to Aardenburh philosophy.

www.wilhelm-research.com/istar/WIR_IST_2007_09_HW_DS.pdf 

because it is very complimentary to the new methods Mark developed. He designed the proposed iStar metric in the WIR article, though the method was not adopted at WIR - or at least was not at the time. Perhaps WIR has a new testing procedure around iStar. Mark can say...

and you can read about Mark's methods directly on the Aardenburg website which you should join in order to support him. 

- read for yourself and choose.

I had already come to the conclusion on my own that inkjet coatings could be a problem just because the manufacturers don't talk about them and are reluctant to tell you what's in them (one just flatly refused to provide an MSDS which is a Federal no-no), but I would like to know why these coatings are a potential problem.

Apparently Wilhelm's tests are being "translated" into some other number that in some cases seems to imply that prints are virtually turning to dust as they issue from the printer <grin>. Anyway, it makes it difficult to compare the numbers for some of the B&W ink sets discussed here to Wilhelm's numbers for OEM inks. The implication that Wilhelm's results are overly optimistic leaves me with no point of reference.

I had started a PDF on the issue, but have not put too much in it.  See http://www.paulroark.com/BW-Info/Arches.pdf  

Basically, the trick in profiling is to use very low midtone ink limits and a very high K limit.  You can see the QTR settings in the PDF.

Arches Hot Press and Cold Press give the best dmax by far for non-coated watercolor papers.  I did a project with a Guggenheim award-winning artist the involved testing a lot of watercolor papers with carbon inks, and the Arches came out on top.  So, start there in your experimenting.

Dick Blick seems to be the best place to buy it.  Use 140 lb.  The 300 lb. will not feed.

Full sheets are 22x30.  I just cut them down.

The dmax I'm getting on the 7800 is mid to high 1.50's.  The 1400 and some other printers can get into the low 160's with Eboni.

I like the texture and look of the Hot Press paper.  Some prefer the more pronounced texture of the Cold Press.  The print and profile essentially the same.

I'm not going to use if for everything, but it's an interesting option.


> On a semi-related topic: I have seen "Wilhelm years" mentioned here several times and could use a reference to an explanation. ...

I'm not going to attempt to answer this, but I'd recommend you go to Aardenburg Imaging and Archives' fade test page at http://www.aardenburg-imaging.com/cgi-bin/mrk/_4346c2hvd19kb2NfbGlzdC80 and pull up any of the test results.  On page 4 of these there is a chart that makes some comparisons.  There are some explanatory notes there also.

Re: [Digital BW] Was: New Aardenburg Imaging fade tests posted/Now Current status of Iris B&W printing

2010-04-09 by Brubaker family

I've been looking for a thread to hijack to get a discussion going about the current state of Iris B&W printing, and Tyler's and the subsequent "rants" of others look like the perfect opportunity!  This is particularly so because I especially wanted to get Tyler's and Jon's inputs.
My interest in this topic started for me when my wife and I were in Apalachicola, FL in early January.  We found that photographer Ron Bickle (ronbiclephotoghraphy.com) has a gallery on the main street of the town, and went in to get a look at his work.  He had on display mostly B&W images from the "forgotten coast" area, and I was impressed by the quality of the prints and the emotional impact several of the prints had on me.  If I had the budget to buy gallery B&W prints, I would have bought several of his on the spot.  (As an aside, I noted how the larger 30X40 prints of the images had so much more visual impact than the smaller prints of the same image.)
My favorite images were:
Baptism at Camel Lake (New exhibits and prints Apalachicola: An American Treasure, American Treasure_17)Saturday on Spring Creek (New exhibits and prints Apalachicola: An American Treasure, American Treasure_16)September at Two Mile (ronbicklephotography.com/PhotoDisplay.cfm?ItemPicture=SeptemberAtTwoMile)
Ron was in the gallery, and I had a chance to talk with him for a few minutes before more visitors came in.  The notes on the prints indicated that they were taken with film, not digital cameras.  I started by commenting on how much detail without grain even the 30X40 prints had, and supposed he was using large format film.  I was surprised when Ron replied that he used 35mm fine grain film and Zeiss lenses.  He noted that for technique he in particular he likes to use wide angle lenses close up.  (Reading "between the lines" I surmise that he probably uses something like a Leica M rangefinder with the Zeiss lenses.)
He said that the smaller prints are silver gelatin, but that the large prints are Iris B&W prints done for him (both scanning and printing) by a printmaker in Atlanta, GA.  The images on the web site don't do justice to the beauty of the prints that were on display.  The tones are a rich (dark) chocolate and light cream and there is no apparent grain even on the 30X40 prints.
So aside from the beauty of the prints, which I hope you will view on his web site, I hope to get a discussion going about the current state of B&W Iris printing and comparison/contrast to the B&W printers and inks discussed on this forum.  (Jon's comments about the impermanence of technology seems especially appropriate re the Iris printers since they aren't being made any more.)
I did some web research on B&W Iris printing and found the following:
The original Iris printers were designed to be used for color pre-press proofs for the graphics/printing industry.
Graham Nash and Mark Holbert (of Crosby, Stills and Nash fame) along with David Coons (software development) adapted the Iris color printer to make B&W prints using Lyson quad black dye inks.
In 1998 Jon Cone developed a set of Digital Platinum B&W inks and a software driver for the Iris printer.
The Iris technology went through a number of acquisitions, with Kodak ended up buying the it, but has stopped manufacturing it.  I'm not sure what the current replacement is.
The technology of the Iris printers is very interesting - I'll let readers look it up on the web.  But, talk about waste ink!

well because it sucks. I can get away with that, perhaps the backlash for you would be too great if you don't maintain a more civilized voice and stance, so thanks for helping to promote generous discourse in this community. 

But I'm sorry, I don't want fine B&W printing to go backwards. I've argued and illustrated the superiority of the multi black systems I have access to, and compared the silver contact print, many times over the years to ABW. But that's just the technical stuff, I have to add that criteria for masterful photography has always had a technical element, it can't be helped, the process includes science. Add to that the visual impact differences. Now many don't see it, or if they do- don't care. Interestingly, often the people who are sensitive to it are those with a strong background in pre-digital fine print. Often people who don't care are new enthusiasts dslr, for whom good B&W was not even possible before ABW, so it is a revelation. We all welcome new photographers, but should they be who set the standards? Are we only trying to supply reasonable solutions to them?

The variety of criteria, and expectations, are huge, why must any of us comply with another's? Why because one person argues to me ABW is outstanding I'm supposed to accept that? I don't expect them to use my setup. In fact, I'm somewhat jealous they have a readily available out of the box solution that makes them happy.

I have old 3000 quad tone prints here I'd take over ABW, in a heartbeat. If it managed to force all other alternatives from the market, I'd make digital negs for platinum or head back to the darkroom. Oh wait, those solutions were crowded out of the marketplace as well. Guess what? ABW and many other "solutions" provided us now are not even as good as the old darkroom by some standards.

Longevity has always been extremely important in photography, and historically one of the greatest scientific challenges. But what's the point of prints that last forever, that fall behind artistically?

Thanks to everyone here working hard to develop systems that result in beautiful print, and/or promote longevity, hopefully we'll get it all, and make prints exceeding the photographic masterful quality of systems 100 years old.

End of incoherent rant...

... and by the way, where the heck is spring?

It sounds more like the "Wal-Mart way" – come in and run small shops out of business with cheaper and lower quality products.  I would think that the American way is supporting a US-based small business that is innovative and which employs US citizens.

Shilesh,

You have utterly and completely missed every point, or possibly I do not understand your response and defensiveness. I'm not certain beer (whether your treat or mine) would improve things.   lol   But, I am willing to take the chance as long as its not a bud light. 

However, thanks for holding me to a higher degree of responsibility than HP, concerning proof of the existence of an encapsulation process that takes place in a world measured in nanometers.

You made me feel like the Peter Sisseck of ink!

Cheers mate!

>

I participate in a monthly exchange of prints, so get to see lots of prints by others. Not everyone in the exchange is highly skilled, but neither is everyone a slouch at printmaking. Some in fact have refined their crafts to a very high degree and are customarily making their own ink mixes. They actually take the potential of inkjet printing to a level higher than anything available commercially (sorry, but higher level than K6/7 in limited attributes). But most use straight-up ABW, and some use linearized ABW. Many have used various flavors of K6/7. These are my objective observations: 
> 
> Generally prints made with K6/7 systems are no better than those made with ABW. Ultimately it is the skill of the printmaker that dictates the quality of the final result, not the tools they used. I am near-sighted, and routinely take my glasses off to view prints nose-to-paper. When I use my view camera, I don't even use a loope for final focus, just take my glasses off, and go nose-to-ground glass. So I know what smoothness is. Never have I sensed that K6/K7 trumps ABW. Under high magnification, sure there is a difference, but it is totally meaningless, and what I call politely "technical self-gratification." So naturally, I ask myself what is all the hubub for K6/K7? I read someone (you or Tyler, or perhaps someone else)recently write something to the effect that the visual superiority, fidelity of K6/7 is not something everyone can see. When I read that, by knee-jerk (and quite possibly totally accurate) read on that was "very few people, or more likely no one will see that difference unless they use a loope." So why bother? Well, you bother because there are cons to ABW, especially selective color fading. So use pre-mixed mono inks. But that comes with a price; you are now stuck with the hue you get with the paper of your choice. No free lunch. In some of your recent post, I have seen a decided view of a balanced approach to selecting the ink choice based on important criteria - that is good to see.
> 
> I personally have no angst about or yearning for the long-gone past; I never practiced darkroom printing, other than printing electron microscope images. So that technology has no emotional meaning to me. I have also participated in LF print exchanges, where contact prints from 8x10 negatives were submitted. Total blah. Not because of the technique, rather because of the photographic and printmaking skills of the authors were limited. It being a contact print on 8x10 Azo has no aesthetic appeal in itself. On the other hand, BO prints made by someone with skills of say Clayton Jones or Nicholas Hartmann were tremenndous. Again, not because they were BO prints, but because these guys knew how best to use the technique. Speaking of Clayton Jones, me maintains a perfectly grounded-in-reality database of papers, Dmax, paper color, print hue, all out of goodness of heart. Why not do the same for Piezo inks?

But, I stopped myself from asking because ironically it does not matter that they are triple or otherwise encapsulated. What matters is the resultant print on paper. There, I have already seen with my eyes that it does not matter at all. Clogging and clumping? I don't know, but I may have to scratch that itch, and see for myself under an EM. My point: please keep the discussion to what is relevant, and truly verified with data. I was surprised that even HP had nothing more tha a schematic of encapulated pigment, not an actual EM image.

ABW is Walmart Special

2010-04-09 by deanwork2003

Well that is more than an ironic metaphor. I went into the Super Walmart the other day, up here in the burbs of Georgia to buy some soap, and low and behold there it was, the Super Walmart digital imaging center, complete with Epson 7880s, cranking out ABW prints by the thousands. I wish I were kidding but I'm afraid that IS what this HAS come to, right now,  artistically created cheaper by the dozen "archival" pigment prints on Sommerset Enhanced. And they didn't even need QTR....
Isn't life great.

In the spirit of continuing with some honest and direct discussion. . . .
 
Aesthetics
 
I have been using Cone inks for a number of years now. I am currently using
the Special Edition and Selenium Piezography (K7) sets, and I am getting the
most beautiful images I¹ve produced to-date. Special Edition has a beautiful
warmth. It blends Sepia shadows gradually into selenium, and then into
neutral highlights. It¹s warm, but not to the extent that straight Sepia is.
I think that¹s part of what I like about it. I am also a fan of split tones,
and in all my dabbling this is the nicest I¹ve seen.
 
Selenium, conversely, is a newer set for me. I¹ve used neutral in past, but
always found it lacking, like it needed something to give it dimension or
spice. Selenium, seems to have that spice, yet is a close cousin of neutral.
I¹m really enjoying the creative contrast that selenium provides relative to
Special Edition. Warm versus cool. They each take an image to a different
place. Both are beautiful ink sets.
 
Longevity
 
Here¹s where I¹m feeling conflicted. I love the look of my prints, as noted
above, but I¹m uncomfortable with the relatively short lifespan identified
in the latest Aardenburg test results (sorry Jon). What I¹ve done is to
break this down in my mind. I find it helps to test things out and think
through them using real life scenarios.
 
I have a customer who has me print images that he¹s taken at his Parish,
images that capture the life and history there. Their desire is to preserve
this history for generations to come, and he¹s a strong voice saying this is
best done using black and white inks on cotton media with no OBA¹s. Based on
Marks¹ work, Special Edition and selenium do not meet this requirement. Cone
Sepia or Paul¹s pigment-only approaches should. The warm sepia-only
aesthetic is not my favourite however, but it¹s likely not an issue for
them. However, I¹m a small volume print maker, and there are practical
implications to adding another ink set.
 
I have another customer, a portrait photographer, who asked me which paper
would provide the greatest longevity with my black / white inks. Her
customer will hang the prints in a really bright room with a lot of direct,
outside light. Mark¹s longevity work equips me with meaningful data to make
informed choices. My current ink sets limit me, but I would like to be able
to offer an appropriate Sepia / paper combination to her.
                                                       
In my own work I have varying requirements in terms of longevity and the
aesthetic. By nature I¹m a perfectionist, and having the ability to produce
the best possible print within my means, is important to me. For work that
is shorter-term in nature, there is no conflict. Longevity is a non-issue.
When I sell a high quality portrait or fine art print however, I have some
angst. I have been careful not to quote the high numbers that many do on
their print documentation. I prefer the term ³decades², which is even
optimistic. Another dynamic however, is reputation. I don¹t want someone
disappointed with my print in 20 or 30 years. Perhaps more importantly, I
don¹t want to be disappointed with how my print looks in 20 or 30 years. The
balance to this of course, is how many of those prints will really be viewed
with this kind of critical eye in 20 or 30 years. Bottom line, if I know
what the limitations of the print are going in, I can provide that
information.
 
So, I ask myself ³Where do I go with all this?². I need longevity in some
cases. I need the creative options available by using more than one ink set
and I want a very high image quality. Right now I swap cartridges in a 13²
printer to provide the flexibility, but I want to move to a larger printer
in the future. My plan has always been to cascade the 3800 I currently use
for colour work, into a monochrome role.
 
Based on this, one solution would be the approach Jon offered to George in
an earlier post today, but with a twist. Run common blacks with 3 shades of
selenium and 3 shades of sepia (versus warm neutral - the twist). This
approach requires sepia to become gloss compatible.
 
shade 1 Matte Black / Gloss Black
Sepia shade 2/3 (50%50%)
Sepia shade 4
Sepia shade 5
Selenium Shade 2/3 (50%50%)
Selenium Shade 4
Selenium Shade 5
Gloss Optimizer
 
Profile the system as follows:
 
1. Straight sepia ­ to meet longevity needs (or provide a warm look)
2. Straight selenium ­ I like the look of selenium
3. Warm / cool split tone ­ profile a scenario using sepia 2/3 for shadows &
¾ tones; 50% sepia 4 / 50% selenium 4 for mid tones (drawing from both two
cart¹s simultaneously); selenium 5 for ¼ tones & highlights. What I¹m really
looking for is something close to Special Edition.
4. Use QTR split toning for various other sepia / selenium mixes. Now that I
think of it, QTR¹s split toning should cover #3.

I could then load this ink set into a 3800 and cover multiple scenarios. I
would trade off some image quality moving from 7 inks to 4, but I would gain
longevity and flexibility. With this configuration I could print with sepia
on the right paper when longevity is the highest priority. When I want
creative choices, I could print using the other profiles on either gloss or
matte media, and in combination with paper choice, have the creative tools I
need. 
 
I keep my costs reasonable by limiting myself to one ink set, and gain the
ability to make larger prints on a very nice printing platform.
 
These are my initial thoughts on how to address the issues. There will be
other ways, I¹m sure.
 
I appreciate the discussions.
 
Terry.

I know enough to know that I'm not at Tyler's level. I'm certainly not

frankly, the talent.

But that doesn't mean that I don't recognize it in them. I had the great 
good fortune of spending a few hours with Mr. Boley last summer. He 
showed me a number of prints. I was just amazed. I've never seen B&W 
prints like that. Over the years I've held quite a few prints in my 
hands to see them without glass -- old masters like Adams and Weston, 
current masters too many to mention. Something to shoot for in my own 
prints even if I'll never get close. But I've never seen any as 
beautiful as Tyler's. I don't have the vocabulary to describe it. He's 
able to make the print subservient to the image, yet support the image 
in a way that makes it just shine. But in the way that individual image 
needs to shine. It'll grab your attention from across the room, yet 
whisper in your ear at the same time. Incredible.

So am I going to enter the discussion? Probably not. I don't have 
anything to say that Tyler and Jon can't say better than I can, and with 
more authority. I've got plenty of bruises already -- I was one of the 
first people to get Piezotones running on a 7600, using StudioPrint. I'm 
just sayin' that bruising is not an issue, and that I know where these 
guys are coming from, and what they are trying to do. I'll always

Those are the people from whom we get progress.

You don't like it? Too bad. Find a way to adjust.

As a long time proponent of monochromatic ink sets, for a variety of reasons, I have often argued in their favor for longevity reasons among many others. Anecdotal evidence and my own lame in house testing seemed to support that near neutral monochrome hues partially made from a variety of highly saturated dots would be less stable on paper over time than an ink actually well designed to make that hue on it's own. Conceptually as well, I would have expected it to be better. Obviously there are a lot of conditions I'm glossing over but you get the idea. We see now, due to Marks invaluable efforts, that some of the OEM inksets including Epson's ABW that include color inks in the hues, are outperforming my favorite inksets in strict longevity terms. There is no way to find fault with the results, or now back down from keeping longevity high on the list of concerns after years of yelling about it, with any credibility.
So it's time to accept that, yield that high ground, give Epson, Canon, and HP props for addressing that concern and making good ink.
Actually, once that is done, I'm not in the least unhappy with the tests results reflecting the inks I use, support, entered for testing. Results are good, just not best. Thanks to David Tobie and others I have vehemently argued with for not immediately beating me up when the results came out.
Anyway, 100% perfect longevity test results are far from the only criteria for me, as I've harped on time and time again. It's a concern, but results so far give me no reason to change, and I'm still thrilled with every other aspect of printmaking activity with the materials I use, just have to walk away from the longevity bragging rights for now. I hope this climate that is so unsupportive of small niche innovative endeavor, allows continued evolution of the materials we need to advance the medium before it dies as Jon predicts.
It felt necessary to get this said and done, a bit of public petard hoisting.
Gee I feel even cleaner now ya know...

Re: Now Current status of Iris B&W printing

2010-04-09 by piezobw

The printmaker in Atlanta would probably be Jamie Cook unless he sold his operation, and the process is ConeTech Unitone, something I designed about 1992. Jamie Cook was one of the first victims which I sold an IRIS 3047 printer to - and he opted to take my methodology training and buy ConeTech software that I developed to make b&w prints using color inks. I was the Development Partner for Fine Arts at the time with IRIS Graphics, Inc.

Unlike Epson ABW which develops density through three shades of black and uses color inks adjacent to black dots to make tone, the ConeTech UnitTone process is quite different and relies on a system of lookup tables to precisely place the color dots of ink under the black dots of ink rather than adjacent to them in the normal IRIS dithering process which was called matrixing.

The IRIS printer forms 31 distinctly different dot sizes comprised of between 1 and 31 droplets of ink. The 31 is theoretical but was actually obtainable via a number of lookup tables working in harmony. The basics of Unitone are to define a tone made of mixing cyan, magenta, yellow and black ink. I predefined a number of tones between warm and cool. This becomes one lookup table for the recipe of inks to make a "tone". 

You can see a picture of the possible tones created with my Unitone process using color inks here:

http://www.piezography.com/PiezoPress/wp-content/uploads/2010/03/unitone.jpg

In terms of data sent to the printer - for every density location, a certain amount of cyan, magenta, and yellow drops of ink are placed immediately under a black dot of ink and in that precise order according to the Unitone recipe. A Photoshop routine is used in conjunction with the lookup tables to prepare the file, because to fill in the spaces left by missing matrix dots of cyan, magenta and yellow, they too are produced by smaller drops of cyan, magenta and yellow hiding under black, produced from CMY image data produced in the Photoshop routine. The end result of UniTone with a strong loupe does not show the tell-tale IRIS matrix and looks virtually continuous tone - and more importantly, you can not see any ink color other than the chosen UniTone. Not a stray cyan, magenta or yellow dot. Every black dot is a UniTone dot.

I have a UniTone print hanging on my own foyer wall that I printed 19 years ago that remains very fresh to this day. The black ink acting to support greatly the more fugitive nature of the color inks. The software was in DOS - and to this day runs on very old versions of Windows by those who opt to keep my system alive. The PC is an older architecture that can support the printer interface cable. This is very archaic technology by today's standards. But at one point more than 40 printers in the USA produced Unitone prints in the mid-1990s. Most went out of business because of the proliferation of Epson printers allowing artists to no longer need the services of fine art service bureaus.

I still run one. They are exceedingly rare and the parts supply is maintained now by ITNH. They're crazy expensive to maintain. But sometimes they print black & white like no other process. I am producing Zana Briski's bug prints right now with my IRIS. Nothing else compares. I'm using UniTone for the project.


DigitalPlatinum was a quad black ink system tied in with media profiles. I believe that this is the first quad black system of inks and profiles ever designed. This one is more complex in some ways, relying on dot placement in conjunction with a variable tone process of inks. Maybe this will help the mad scientists here. Shade 1 was black, but shade 2 and shade 3 had the same density (middle gray) and were used to modulate the mid-tones into several possible tones depending upon how much of one was used in comparison to the other. One of these two inks was greenish/brownish, one colder/brownish. The forth bottle was in two options and used to influence the highlight split. It was the light gray and you would change it out depending upon the effect like how paintings are glazed. One was neutral and the other very warm.

You can see a picture of a replicant of Ziatype printing that I could produce with DigitalPlatinum here:

http://www.piezography.com/PiezoPress/wp-content/uploads/2010/03/weese2-900.jpg

The photographer is Carl Weese and the split toning imitates the printing out process which gets warmer with greater exposure. But it could also imitate many other styles of platinum printing quite different than this. I never licensed it preferring to keep it only for my studio.

Diana Michener's Solitaire exhibition at Pace McGill was DigitalPlatinum - I think I printed it in 1997. It had a much more selenium look to it and was produced on extremely delicate japanese paper. Some of the software I made to do the Ashes and Snow prints for Gregory Colbert came out of DigitalPlatinum. That took 11 inks and yet was in no way as delicate as DigitalPlatinum with 4 inks.

I really do not believe that any other inkjet process will ever replicate the beauty of the surface of this type of printing - yet it also fits into the category of something felt and perceived rather than some data that can be understood. The process of 31 sized variable dots of ink is a very powerful asset to making photographic prints on uncoated papers. But, the majority of IRIS printmakers used coated papers and Scitex software and these types of IRIS prints are more ordinary looking and perhaps lower in visual quality to Epson 7000 color prints.

Re: Now Current status of Iris B&W printing

2010-04-09 by john

Jamie is pretty much retired. After everyone started buying Epson printers I think he just got bored with it all. He does his own work now. He found out I had a Z3100 and wanted to come look at the results. Then the next day he bought the Z3200 and I helped him set it up. 

I think the three Iris 3047s are retired now.

In a related note a collector friend of mine had prints done here on that Iris with the  IRIS Equipoise inks. I was organizing the collection and putting things away. Those black and white prints that were in dark storage have shifted all kinds of strange colors with magenta and green streaks across them. Not pretty. We threw them away. Those are 10 year old prints and quite expensive in their day. Permanence matters. That work is gone.

Apparently Wilhelm's tests are being "translated" into some other number that in some cases seems to imply that prints are virtually turning to dust as they issue from the printer <grin>. Anyway, it makes it difficult to compare the numbers for some of the B&W ink sets discussed here to Wilhelm's numbers for OEM inks. The implication that Wilhelm's results are overly optimistic leaves me with no point of reference.

True "Wilhelm display life years" involve two major factors that most people simply don't take the time to understand (i.e., they are happy just to accept the predicted years at face value):  1) the WIR display prediction is derived using a "normative" light level in the display environment of 450 lux for 12 hours per day, yet real world display light levels can actually vary around this normative level by three orders of magnitude.  2) A criterion to decide "end of life" is required (i.e., are we talking about a little fade,  moderate fade, a huge amount of fade, or image totally gone!). WIR describes the endpoint of the test as "easily noticeable fade". To understand just how easy is easy and where these densitometric criteria go wrong with modern digital printing media, one needs to study the WIR 3.0 "visually weighted" endpoint criteria set which has 13 different threshold values.  Unfortunately, even if you take the time to understand how the ratings are calculated, the determining threshold factor is not published, so we don't know how the sprint sample is actually failing. The specific failure mode can have significant bearing on what system is best for a particular image. For example, a print that tends to show highlight yellowing (e.g., loss of optical brightener activity) would be more problematic for the white dress in a bridal portrait, not nearly so visually apparent in a dark and brooding landscape scene.

When Paul described the AaI&A rating for the K6 neutral sample as 18.5 Wilhelm years, he was using the AaI&A table in the report in order to convert the 37 megalux hour rating into "years on display" by selecting  the same WIR value of 450 lux for 12 hours per day. Thus, the 18.5 year AaI&A prediction at that light level is on the "WIR display time scale", but it definitely does not use the WIR densitometric criteria set to establish the amount of fade which occurred in test up to that point. The AaI&A Conservation Display ratings are based on "little or no noticeable" fading rather than "easily noticeable" fading, and they use a colorimetric rather than densitometric model for judging changes in image color and tonal appearance. Thus, the apparent disparity in ratings between AaI&A and other testing labs is caused not so much by the basic accelerated nature of the testing, rather the overall criteria used to define how the scores are achieved.

It's important to realize that the current industry-sponsored tests were developed originally for consumer-oriented photofinishing applications.  I can assure you that the types of hue and tonal nuances that are being debated between ABW and other monochrome inkjet printing methods in this forum are way too subtle to have any meaningful impact on a consumer-oriented "easily noticeable" fade rating. Thus, "easily noticeable fade" is, IMHO, too liberal a fading endpoint for fine art, but it's a totally valid goal to evaluate how a print is faring in mid-to late stages of deterioration. Because systems often fade non linearly, early stage fading may not be a good indicator of late stage deterioration and vice versa. Full system characterization needs at least three points to define the fading curve which is why AaI&A reports results at multiple exposure intervals and doesn't stop the tests when the AaI&A conservation display limits are reached. The AaI&A conservation display ratings estimate early stage fading performance only.  

Lastly, I want to add that I personally don't view print permanence testing as a game of "winners and losers".  It's about helping the end-users of various processes to make informed choices.  As others have eloquently said in this forum, the artist should first and foremost choose a process that imparts the aesthetic he or she visualizes for the created image. I've seen beautiful ABW prints, and I've seen exquisite B&W inkjet prints made with single channel, three channel, four channel, on up to seven channel monochrome ink sets,  but in each instance the artist made intelligent choices in image selection, image edits, ink, paper, coatings, etc.   Sometimes, the best choice involves a compromise in print permanence, but sometimes the best choice also happens to be highly durable as well.  We can certainly ignore print permanence testing and lull ourselves into a false belief that if it's a "pigment print" it must be "archival" (whatever that means), or we can take the time to discover the print durability strengths and weakness of our chosen processes. Adding print permanence information to the list of variables that should concern the artist helps to cut the bull$*#& and to choose wisely... even if the final choice is to use a fragile but aesthetically beautiful process.

Lots of very informative answers that I do appreciate, but I still don't have an answer to the basic question (I think I have also inadvertently demonstrated that Warhol was right and I am getting Intro 101 answers about longevity because my 15 minutes were more than a decade ago): 

What does 18.5 Wilhelm years MEAN? Is it like dog years (tongue firmly in cheek)? Who came up with "Wilhelm years" and how do those numbers relate to the published Wilhelm numbers?

I see 18.5 years and I am entirely unimpressed, so I must assume some other meaning is involved.

Bravo Mark.

I'm going to print that out and put it in the longevity file that I've been collecting.

The  beauty of your method is that you can SEE what is  going on in real time right on the website by  observing the changes in all the hues and values at specific intervals. And anyone else can submit the same ink/paper combination to back that those results up.

So, is  Wilhelm's end point a fade rate of aprox 35% as I believe Jon Cone has suggested in the past?  I mean he's got to have some objective criteria other than - oh well  my 60 something year old eyes see a definitive change therefore we stop here? What percentage is Wilhelm using to stop the test and declare it an end point. I still don't understand that.

> True "Wilhelm display life years" involve two major factors that most people simply don't take the time to understand (i.e., they are happy just to accept the predicted years at face value):  1) the WIR display prediction is derived using a "normative" light level in the display environment of 450 lux for 12 hours per day, yet real world display light levels can actually vary around this normative level by three orders of magnitude.  2) A criterion to decide "end of life" is required (i.e., are we talking about a little fade,  moderate fade, a huge amount of fade, or image totally gone!). WIR describes the endpoint of the test as "easily noticeable fade". To understand just how easy is easy and where these densitometric criteria go wrong with modern digital printing media, one needs to study the WIR 3.0 "visually weighted" endpoint criteria set which has 13 different threshold values.  Unfortunately, even if you take the time to understand how the ratings are calculated, the determining threshold factor is not published, so we don't know how the sprint sample is actually failing. The specific failure mode can have significant bearing on what system is best for a particular image. For example, a print that tends to show highlight yellowing (e.g., loss of optical brightener activity) would be more problematic for the white dress in a bridal portrait, not nearly so visually apparent in a dark and brooding landscape scene.

> When Paul described the AaI&A rating for the K6 neutral sample as 18.5 Wilhelm years, he was using the AaI&A table in the report in order to convert the 37 megalux hour rating into "years on display" by selecting  the same WIR value of 450 lux for 12 hours per day. Thus, the 18.5 year AaI&A prediction at that light level is on the "WIR display time scale", but it definitely does not use the WIR densitometric criteria set to establish the amount of fade which occurred in test up to that point. The AaI&A Conservation Display ratings are based on "little or no noticeable" fading rather than "easily noticeable" fading, and they use a colorimetric rather than densitometric model for judging changes in image color and tonal appearance. Thus, the apparent disparity in ratings between AaI&A and other testing labs is caused not so much by the basic accelerated nature of the testing, rather the overall criteria used to define how the scores are achieved.
> 
> It's important to realize that the current industry-sponsored tests were developed originally for consumer-oriented photofinishing applications.  I can assure you that the types of hue and tonal nuances that are being debated between ABW and other monochrome inkjet printing methods in this forum are way too subtle to have any meaningful impact on a consumer-oriented "easily noticeable" fade rating. Thus, "easily noticeable fade" is, IMHO, too liberal a fading endpoint for fine art, but it's a totally valid goal to evaluate how a print is faring in mid-to late stages of deterioration. Because systems often fade non linearly, early stage fading may not be a good indicator of late stage deterioration and vice versa. Full system characterization needs at least three points to define the fading curve which is why AaI&A reports results at multiple exposure intervals and doesn't stop the tests when the AaI&A conservation display limits are reached. The AaI&A conservation display ratings estimate early stage fading performance only.  
> 
> Lastly, I want to add that I personally don't view print permanence testing as a game of "winners and losers".  It's about helping the end-users of various processes to make informed choices.  As others have eloquently said in this forum, the artist should first and foremost choose a process that imparts the aesthetic he or she visualizes for the created image. I've seen beautiful ABW prints, and I've seen exquisite B&W inkjet prints made with single channel, three channel, four channel, on up to seven channel monochrome ink sets,  but in each instance the artist made intelligent choices in image selection, image edits, ink, paper, coatings, etc.   Sometimes, the best choice involves a compromise in print permanence, but sometimes the best choice also happens to be highly durable as well.  We can certainly ignore print permanence testing and lull ourselves into a false belief that if it's a "pigment print" it must be "archival" (whatever that means), or we can take the time to discover the print durability strengths and weakness of our chosen processes. Adding print permanence information to the list of variables that should concern the artist helps to cut the bull$*#& and to choose wisely... even if the final choice is to use a fragile but aesthetically beautiful process.

Bruce,

What I said was totally out of line - please accept my apologies. I wish I had restrained myself.

On to the substantive matters. Clearly you admire Tyler's print making skills from first hand experience. I have not seen any prints made by Tyler, but have no reason to doubt that he posseses highly refined skills. That is one of the points I have been trying to make. He makes K6/7 or whatever he uses sing a sweet song. Others have made ABW sing with as much impact, and so with BO, with the many MIS inks. Yet all of these technologies have poor practioners too. Technology does not trump skills. Technology does make better prints, printers make better prints.

This time, respectfully,

Shilesh

Walmart is the America way, like it or not. What is even more American is to start small, beat Walmart at it's own game, and endevour to be next behemouth. And so the cyle goes. There are plenty of carcasses of previously dominant companies.

Do something inventive that will knock Epson, HP, Canon off their respective perches. Whinig about their restrictive practices, well that is just sour grapes, and decidedly un-American.

Re: ABW is Walmart Special

2010-04-09 by shileshjani

An honest appraisal for ABW would be Honda Accord - gets you where you want to go with least amount of fuss, reliably, on time. The ride is boring.

Some other higher solutions are like those expensive cars that are a great ride, even if they spend a lot of time in the workshop. I do not want to insult anyone with names of high end, but unreliable cars.

Why am I defending ABW? I don't even use the damn thing much. Must be because I have seen too many good prints with ABW. If it allows ordinary people (including Walmart) to make good prints, well that is the American way - stick it to the uber-class elites.

Re: [Digital BW] Reply to Jon and Tyler re ABW - Was Aard. Tests

2010-04-09 by Walker Blackwell

I've been reading this thread a bit. I think the "print as object" is really what we are all fascinated by. And the more varied ways we get there, the better. My focus has always been to make the most interesting print possible in whatever way possible. I went to digital because it was commercially viable and I liked the quality of matte ink prints that you just couldn't get in the darkroom. 

But if I needed to go back into the DR for a project because that is what the project called for, I wouldn't hesitate for a second. But (in my current imaginings for some recent work I'd do in the DR) I wouldn't just automatically  be printing with some default paper/dev combo. I would be using Dektol and most likely Berger paper. Or maybe Dektop and Ilf MG. That would be a specific decision that I would make along with the lens/light-source, etc.

I guess what I'm trying to say is that there is nothing wrong with ABW vs K7 vs Silver. The only thing wrong is if you are using that process because a: it's the easiest available process, b: you compromise some amount of your creative will to it, c: it's not because it does something for you that no other process can do.


On the technical side . . . .


I've used the following digital BW processes and I can personally rate them as such (taking out paper variables—etc).

K4 (SP3000) Great at its time. Better physical res for any BW dig print I had seen yet.
Double K4 (SP7000) Same as 3000 but seemed to have better physical resolution.
K6 (SP7000) (not as good as double K4 with the stuff I was printing. Too many dots.)
CMYK icc RIP 9600 (Spend 3000 dollars wasting paper and never got a great profile that could print as good as ABW or K4 or QTR.)
QTR K2 9600 (great. A bit less detail in shadows than K4 or K7)
K7 (SP9600) (Whoa!! The first time I could rival the quality of a larger than 20x24 silver print in resolution and shadow detail.)
K4Split (SP9600) (Split toning without metamerism! Yeah!)
K7 (SP4000) (Holy sh%t look at that detail!) === current small format printer.
QTR K3 (SP4800, SP4000) (Total flexibility in hue in all three tonal regions. Open-source. You can build an ICC linearization for it. Less shadow fidelity than K6/7 but maybe more than K4 single on the 9600)
QTR K7 (SP4000, SP9600) (I actually like Studioprint better. I cut my teeth on that system and I feel like it's more luminous. K7 feels too perfectly linearized. Too flat.)
ABW (11880, 3800, 4800) with Epson Ink (11880 rocks. The other printers show a lot of metamerism. It just doesn't fly in differing light sources for me. Compare them to silver prints and they lack spirit to me.)
ABW (4800) Cone Ink. (ech. Don't try. The driver can't be internally linearized.)
QTR (4800) Cone ink. (less metamerism than 3800 ABW in my opinion. QTR puts more K down than ABW. It rules ABW anyday in my book and gives you more toning options + internal linearization and won't f' up every time Apple updates their OS.)

I might of missed a few in there. Some 9800 stuff.. My brain is fuzzy. 

For me, it's never been all about longevity.  It's been about how shifty the inks are under different light sources. If my print only looks good under one light source, I feel like it's only 1/3 of a print. ABW (besides the x900s and the 11880 and maybe 3880) really doesn't have as good in-room color stability as QTRK3 or the HPZs and those printers still don't compare to even old K4s on the 9600 when it comes to just how adaptable they are as a BW object in a real-world gallery situation.

For those who like the adaptability of ABW, go with QTR. It's just better in my opinion because it gives you more options and a better looking print in XYZ room. QTR (in other-words) is actually "more ways" combined than ABW.

This is just my opinion after years of dealing with artists all of whom have their own wants and opinions.

all the best,
Walker

That is absolutely true. 

Skills do trump technology, no question about it. Big time.  And when the most refined technology for a particular outcome is carefully matched and mixed, and finessed to the photographers needs, as is evident in Tyler's personal work, you have something that does not come out of a corporate workflow, it comes out of a labor of love.

He sent me some prints a couple of years ago from a portfolio of nudes that were printed with a blended Studio Print controlled, Piezo inkset specifically designed for that particular portfolio and never used again. This is the kind of thing that Cone excels in.  They were even coated with a hand mixed  unconventional varnish technique to seal and augment the spectacular hues and tonality of the work. In inkset designed specifically for that body of work. I've never seen anything like that - K7 at it's best. No technology created that, a great craftsman did. But this craftsman wanted and needed the unique tools and inks to make it happen. It comes from decades of study and hard work and is not something that comes out of a box made by any corporation, as useful as that corporation may be becaue of their own innovations.

If people seem a little over protective of the need to have this variety of unconventional  tools and materials available to them that don't come out of a box from the local photo store it is because they see the value in that uniqueness. If they didn't need it they wouldn't waste their time clinging to it.  Not everyone needs or wants that option, most don't,  but there are plenty of us still alive that do want it. I hope we can keep it all and have enough variety to go around and satisfy us all. And, I hope we can make the prints last as long as possible.

Re: Now Current status of Iris B&W printing

2010-04-09 by piezobw

Equipoise ink had some issues during its history, John. And Equipoise should certainly never have been used on any paper with an inkjet coating. But unfortunately, most Iris printers used the coatings to get dMax when Hahnemuhle and others offered IRIS sized sheets with coatings. There will be a lot of those prints out there. Maybe even the majority of them. The ones you describe sound indicative of a poor ink choice. In this case, the OEM did not make the better mousetrap - and it was designed to be "archival".

By the way, Jamie is about the nicest and fairest guy you could ever meet.

Hello Walker,

Interesting post, thanks.  I enjoyed reading through the list of systems you've used - you certainly have a lot of perseverance.  

I have some comments about ABW metamerism.  It's an important subject and wasn't mentioned in the other threads.  I've used a 2400 approaching five years now (will be 5 in August), and during that time I've tested lots of different papers for my "Paper Chase" review page.  It was a unique opportunity to see how the inks react on a wide variety of papers.

I've found that some papers take K3 inks beautifully, where it's easy to find tone settings that look great and  exhibit little or no metamerism (I test under 5 different light sources here: real daylight, full spectrum flourescents, pure incandescent, mixed incandescent + 5000k compact fluorescent, and a pure 6500k compact fluorescent).

There have been other papers with which I never could get a satisfactory result.  The most notable example was HPR.  It was a favorite when I used Eboni based inks - the best Dmax and beautiful tones.  Naturally when I got the 2400 it was one of the first I tried. It was an exercise in frustration and I spent an ungodly amount of time, ink and paper trying unsuccessfully to make it work.  I never could find a setting that didn't look colorized (some hint of green or pink) and metamerism up the wazoo.  In addition, the Dmax wasn't near as good as with Eboni.  For whatever reason, HPR and K3 are not a good match (I've often wondered if people who didn't like ABW were trying to use their favorite HPR with it and gave up on it).

At the other end, I discovered that VFA, which with Eboni had good but not great Dmax and just ok general appearance, became with K3 the highest Dmax paper of them all and has really beautiful tones and a wonderful glow.  Just gorgeous prints.  With my favorite nearly neutral, slightly warm tone it exhibits little or no metamerism.  

Other papers had various degrees of the above characteristics.  Some worked easily and some were difficult.  The point is that the ABW system is persnickity and different degrees of metamerism can appear among different papers.  However, with some effort and careful paper selection really fine results can be produced.  

Your report is the first time I heard that one printer model may produce different metamerism than another.  I'm just wondering if the paper and settings used may have been the difference, rather than the prnter model.  What do you think?


Regards,
Clayton

It was the same mistake that made Lyson's Fotonic and Lysonic dye inks

Re: [Digital BW] Reply to Jon and Tyler re ABW - Was Aard. Tests

2010-04-09 by Walker Blackwell

Well. That's good to know that VFA works well with ABW (with ? printer using ? LUTs). My own samples tests on the paper with ABW look pretty good as well.

I guess my main thing is, if the BW process is limiting your paper choices why invest all of your time into it. I would never use an enlarger I could only print onto one or two kinds of silver paper with.

I would suggest (to all you who are using ABW but struggling with shifting under different light sources) setting up both ABW and QTR and seeing the differences between to the two on the same printer. This way you know for sure you're getting everything you can out of the machine. Both have differing characteristics. But it's those difference qualities that can really further the art.

Just my two cents,
Walker

Maybe that was why all my Lyson Small Gamut "neutralized" prints turned green. I had to reprint several of those for people. Thankfully I only used them for 2 years off and on and didn't do any major portfolios with them.

John,
First time you were aware of that?.. Ole Wally world has been doing this for a while.. Not every store has them .. They (Epson)  even did special training programs for them..  We laughingly say they probably tried to pirate operators from Kinko's  ...fancy that.. Stepping back.. now just a bit further.. Epson set up a competition base to their own customers.. realistically we could all say they don't have the quality. But in truth they do if the image produced is deemed acceptable by the customer.

Right, Jim, it's a race to the bottom.

Well, apparently I didn't do a very good job explaining it in my first post, so here goes again.

18.5 Wilhelm years is about 74 Kodak years! Clear as mud, right? The different "years of display life" predictions come about because Kodak, Wilhelm, Image Engineering, Torrey Pines, IPI, etc. make their predictions by extrapolating the tested light exposure dose to different assumed "average" light levels on display in the real world. For example, Kodak assumes 120 lux for 12 hours per day whereas WIR assumes an average of 450 lux for 12 hours per day. Neither is right and neither is wrong because real world print display conditions run lower than 10 lux all the way up to greater than 5000 lux for 12 hours per day. Pick your own assumed level. It is an enormous range for any lab to be just assuming one "appropriate" value, and it's precisely why AaI&A elects not to assume just one normative level for predicting print life. Better to give the exposure dose in megalux hours and let the end user choose a light level condition for display that fits his/her real world viewing situation.

This is all classic exposure reciprocity law (i.e. exposure = intensity x time), so if you assume 4x more light on the print, then the fading is assumed to occur 4x faster. Hence, the sample in question would reach fading levels that trigger the AaI&A conservation display limits in 18.5 years if exposed to 450 lux-12 hours/day light exposure doses but it would take 74 years to get to a similar level of fade if displayed at 120 lux-12 hours per day.  And if a museum curator were to specify 50 lux for 12 hours per day, this particular print would "last" up to 167 years on continuous display. Yet, place the print in a a hotel lobby with atrium skylights, and daily light levels could easily reach 2000 lux, so now that same print will "last" about 4 years.  So, that's the light-induced fading impact of various display locations on this 37 megalux hour rated print process.  If this sample had been rated at 74 megalux hours then you get to double all the predictions which would, for example, then  give the hotel lobby location 8 years of display time rather than 4.  The print's real world environment clearly alters the " life prediction" by an enormous amount which is why AaI&A doesn't do the extrapolation for you, we provide the megalux hour ratings and let you make your own assumptions about the light levels at your display location.

Now, if you noticed I kept putting the word "last" as in "how long will my print last"" in quotes. This is also very important!!!. It is because all of these print life rating schemes have to define some kind of appropriate endpoint of the test. We can fade a print just a little or we can fade it a lot. In each case, the allowable amount of fade also has a large impact on the rating (not as much as assumed light levels, but still huge). The AaI&A conservation display rating deliberately uses a "little or not noticeable" fade criterion which is suitable for fine art, but in so doing, the rating is DEFINITELY NOT describing some catastrophic failure of the image. The AaI&A conservation display rating tells the end user the exposure dose (usually reported as a range rather than a single value) that the print will tolerate and still remain in visually excellent condition. WIR and other test labs use a more liberal consumer tolerance based on easily noticeble fading. This is an appropriate endpoint assumption for consumer ratings since many consumers do tolerate huge amounts of print fading before they attempt to have a copy print made or throw the print away.  Again, the printed image hasn't disappeared into oblivion, but it is noticeably faded, and at a level of fade that, IMHO, would be of serious concern to the discerning print collector.

Lastly, it's impossible to make a holistic or comprehensive print life prediction. Temperature, humidity, seasonal cycling, handling abuse, air pollution, and light all take their toll on a print, and while we can test for the sensitivity of prints to these various degradation processes and provide highly relevant information, we can't realistically combine the results to form one single, unifying, comprehensive overall rating. But that doesn't mean knowledge about the individual degradation pathways isn't important. For example, when the curators set light levels at 50 lux they are more or less taking the light-induced degradation pathway off the table for this 37 megalux hour rated print. It will probably show signs of age from other deterioration mechanisms before light induces any noticeable problem, but the exact opposite is true if it goes into the hotel lobby location. There, light will indeed be a primary agent of change on this print.

Ok, the last lastly: (ranting has been a popular theme in this thread!). The conservation display rating for the k6 neutral sample that was tested (and got this thread going) puts this print sample into a category of print processes most curators/photo conservators would call "moderately light fast".  It beats Fuji Crystal Archive paper ,for example, which is a color print processes also considered to have moderate but not high light fastness.  The museum world deals every day with works of art that are much more light sensitive. They  would achieve AaI&A conservation display ratings as low as 0.1 megalux hours, and hence fade significantly in a matter of days in that hotel lobby location! 100 Megalux hours and greater is a rating that I especially like to see, and some of my tested samples have gotten there!  A 100 megalux hour rating pretty much guarantees in all but the brightest display locations that light induced fading probably won't be the determining death factor in the print life equation.

Now, I should go have that beer with Jon, Tyler, et al!

cheers,

Mark

  That is absolutely true. 

  Skills do trump technology, no question about it. Big time. And when the most refined technology for a particular outcome is carefully matched and mixed, and finessed to the photographers needs, as is evident in Tyler's personal work, you have something that does not come out of a corporate workflow, it comes out of a labor of love.

  He sent me some prints a couple of years ago from a portfolio of nudes that were printed with a blended Studio Print controlled, Piezo inkset specifically designed for that particular portfolio and never used again. This is the kind of thing that Cone excels in. They were even coated with a hand mixed unconventional varnish technique to seal and augment the spectacular hues and tonality of the work. In inkset designed specifically for that body of work. I've never seen anything like that - K7 at it's best. No technology created that, a great craftsman did. But this craftsman wanted and needed the unique tools and inks to make it happen. It comes from decades of study and hard work and is not something that comes out of a box made by any corporation, as useful as that corporation may be becaue of their own innovations.

  If people seem a little over protective of the need to have this variety of unconventional tools and materials available to them that don't come out of a box from the local photo store it is because they see the value in that uniqueness. If they didn't need it they wouldn't waste their time clinging to it. Not everyone needs or wants that option, most don't, but there are plenty of us still alive that do want it. I hope we can keep it all and have enough variety to go around and satisfy us all. And, I hope we can make the prints last as long as possible.

Re: [Digital BW] Reply to Jon and Tyler re ABW - Was Aard. Tests

2010-04-09 by Michael King

Hi all,

Clayton said >>Your (Walker) report is the first time I heard that one
printer model may produce different metamerism than another. I'm just
wondering if the paper and settings used may have been the difference,
rather than the prnter model. What do you think?

I think one variable that might be driving the divide in ABW opinion in this
thread, is which generation of Epson printer you have tried / seen ABW
prints from. Epson has continued to improve ABW dramatically with each
printer version. I used it on the 4800 and the 7880 - big step jump in the
ABW dithering quality between the two printers, same settings same paper
just different printers. With the 4800 IMO glossy ABW was unusable because
of the colour banding in the dithering. But with the 7880 that was
effectively gone. In matte the 7880 again has better dithering, it looks
better than the 4800 but not as dramatically better as the glossy prints.
Walker also comments that the 11880 was way better than the x800.

So I think all of you that don't believe in ABW should have the courage to
take a look at some ABW prints from the latest Epson printers, by a skilled
printer.

However that said, ABW has some real limitations;

1) it doesn't support split toning
2) it has very poor shadow control even using ICC
3) it uses quite a bit of coloured ink in the mix - especially if you want
gentle sepia toning and the Epson yellow is a fast fade ink.... -  this is
the killer for me. I am not fanatical about fade resistance, but I do want
my prints "colour" to last say 20 years. Could be solved by loading an light
carbon ink in place of Y, but that would upset colour printing, require PK /
MK switch as well, all expensive on ink and a pain to switch.

1 & 2 are solvable by using QTR and Epson inks. Solving (3) requires one or
more non-Epson inks.

Also I wanted to experiment with the R1900 small 1.5pl dot size on hand held
prints and this also allows me to load up a number of different custom ink
sets without the huge cost of doing that in LF (cartridges and ink
costs). All that lead me to using custom ink sets in R1900s.

Meanwhile Epson is clearly continuing to up its game with the x900 printers.
Looking at the Aardenburg 9900 ABW result so far, there is fade in density,
but "neutrality" remains almost perfect. Epson has clearly managed to
control the ink fade in the 9900 ABW mix, for maintaining "colour".
Unfortunately if you look at the 9900 colour print fade tests the Yellow ink
is still the Achilles heel, which suggests that sepia splits will not be
very fade resistant.

To conclude, there are a number of digital choices available, all have
strengths and weaknesses, but in the right hands I think they are all
capable of creating great prints with relative ease (compared to analogue)
and that's what I find exciting.

Mike

Your main issue has always been the images you could produce; and no one has ever had any criticism about them. My response (mostly to keep this list looking at all of this in perspective) has been that, once one moves beyond pure carbon, the color used to tint it (even to tint it to neutral for the media involved) can be from full color carts; in fact there is some theoretical advantage to that, as it avoids printing highly diluted color dots (more prone to fading) and avoids mixing colors into carbon inks (prone to differential settling and thus uncontrollable color variation). 

My follow up comment has always been that from typical viewing distances those color dots are not a visual issue, in terms of grain, though they still do their job of tinting. You may still choose to disagree on that point, as it is unrelated to the longevity point that Mark's testing has more clearly illuminated. 

There is a third point worth noting. After ceasing to develop toned B&W ink sets, for the reasons noted above; I proceeded to develop an ICC profile based system for printing, adjusting, and softproofing B&W and tinted B&W prints (which is built into the current Spyder3Print SR product, though it was calling PrintFIX Pro 2.0 at the time). This system was often dismissed out of hand on this list due to the fact that it used the color printing mode of the printers. This meant colored dots, as noted above; and with some drivers it even meant a few MORE colored dots than the drivers B&W method (it actually can be used to profile the driver B&W modes as well, but then it is merely a linearization tool, as all it's color control capability has been taken away).

I would like to point out that this system is now equally vindicated in termed of longevity; against any other color controlled method, and that the inclusion of yet a fee more microscopic color dots in some drivers doesn't really change the visual results either. 

So, anyone looking to produce long life, controlled tint images, including cross-tints unavailable through driver B&W solutions, and offering easy adjustment tools and the ability to preview densities and tonalities as both soft proofs on screen, and in hard proofs from the printer, for standard drivers, high bit export modules, and a number of specialty drivers and RIPs, should consider the Spyder3Print SR solution, which still offers all of that, with even more clearcut assurances of longevity. 

Oh, and the same system, even the same profiles, can be used for color printing as well, which is the other main advantage of this type of solution. And if Tyler Boley was using it to build profiles and make prints, then there would be some really impressive sample images available. ;-)

But Tyler is using other solutions, and I sure can't argue with his results.

Thank you Mark for your clear explanations about print longevity.

To see how temperature and humidity may affect print life, the RIT Preservation Calculator may be of good use:

Well that was even better. Excellent. I just wrote out the same thing for a client who using type C material and want's to know the various possibilities. But your version was much better.

 You need to put that statement right on the website.

As to the Neutral K6/7 tests. If I'm not wrong, there is only one sample by one person that was tested on one paper, right? Since then I have submitted two more of the same inks, one on a completely different brand of paper, as well as the HP monochrome samples, Piezo K7 Carbon Sepia etc. But those will take a while to determine. The Selenium K7 set is also in test by someone else.

One thing that seems very certain is that the Piezo Carbon Sepia K7 is a totally beautiful inkset, even effortlessly out of QTR with Jon's curves. I'm starting to use it for my personal work almost completely. It's testing very well.

> 18.5 Wilhelm years is about 74 Kodak years! Clear as mud, right? The different "years of display life" predictions come about because Kodak, Wilhelm, Image Engineering, Torrey Pines, IPI, etc. make their predictions by extrapolating the tested light exposure dose to different assumed "average" light levels on display in the real world. For example, Kodak assumes 120 lux for 12 hours per day whereas WIR assumes an average of 450 lux for 12 hours per day. Neither is right and neither is wrong because real world print display conditions run lower than 10 lux all the way up to greater than 5000 lux for 12 hours per day. Pick your own assumed level. It is an enormous range for any lab to be just assuming one "appropriate" value, and it's precisely why AaI&A elects not to assume just one normative level for predicting print life. Better to give the exposure dose in megalux hours and let the end user choose a light level condition for display that fits his/her real world viewing situation.
> 
> This is all classic exposure reciprocity law (i.e. exposure = intensity x time), so if you assume 4x more light on the print, then the fading is assumed to occur 4x faster. Hence, the sample in question would reach fading levels that trigger the AaI&A conservation display limits in 18.5 years if exposed to 450 lux-12 hours/day light exposure doses but it would take 74 years to get to a similar level of fade if displayed at 120 lux-12 hours per day.  And if a museum curator were to specify 50 lux for 12 hours per day, this particular print would "last" up to 167 years on continuous display. Yet, place the print in a a hotel lobby with atrium skylights, and daily light levels could easily reach 2000 lux, so now that same print will "last" about 4 years.  So, that's the light-induced fading impact of various display locations on this 37 megalux hour rated print process.  If this sample had been rated at 74 megalux hours then you get to double all the predictions which would, for example, then  give the hotel lobby location 8 years of display time rather than 4.  The print's real world environment clearly alters the " life prediction" by an enormous amount which is why AaI&A doesn't do the extrapolation for you, we provide the megalux hour ratings and let you make your own assumptions about the light levels at your display location.
> 
> Now, if you noticed I kept putting the word "last" as in "how long will my print last"" in quotes. This is also very important!!!. It is because all of these print life rating schemes have to define some kind of appropriate endpoint of the test. We can fade a print just a little or we can fade it a lot. In each case, the allowable amount of fade also has a large impact on the rating (not as much as assumed light levels, but still huge). The AaI&A conservation display rating deliberately uses a "little or not noticeable" fade criterion which is suitable for fine art, but in so doing, the rating is DEFINITELY NOT describing some catastrophic failure of the image. The AaI&A conservation display rating tells the end user the exposure dose (usually reported as a range rather than a single value) that the print will tolerate and still remain in visually excellent condition. WIR and other test labs use a more liberal consumer tolerance based on easily noticeble fading. This is an appropriate endpoint assumption for consumer ratings since many consumers do tolerate huge amounts of print fading before they attempt to have a copy print made or throw the print away.  Again, the printed image hasn't disappeared into oblivion, but it is noticeably faded, and at a level of fade that, IMHO, would be of serious concern to the discerning print collector.

Temperature, humidity, seasonal cycling, handling abuse, air pollution, and light all take their toll on a print, and while we can test for the sensitivity of prints to these various degradation processes and provide highly relevant information, we can't realistically combine the results to form one single, unifying, comprehensive overall rating. But that doesn't mean knowledge about the individual degradation pathways isn't important. For example, when the curators set light levels at 50 lux they are more or less taking the light-induced degradation pathway off the table for this 37 megalux hour rated print. It will probably show signs of age from other deterioration mechanisms before light induces any noticeable problem, but the exact opposite is true if it goes into the hotel lobby location. There, light will indeed be a primary agent of change on this print.
> 
> Ok, the last lastly: (ranting has been a popular theme in this thread!). The conservation display rating for the k6 neutral sample that was tested (and got this thread going) puts this print sample into a category of print processes most curators/photo conservators would call "moderately light fast".  It beats Fuji Crystal Archive paper ,for example, which is a color print processes also considered to have moderate but not high light fastness.  The museum world deals every day with works of art that are much more light sensitive. They  would achieve AaI&A conservation display ratings as low as 0.1 megalux hours, and hence fade significantly in a matter of days in that hotel lobby location! 100 Megalux hours and greater is a rating that I especially like to see, and some of my tested samples have gotten there!  A 100 megalux hour rating pretty much guarantees in all but the brightest display locations that light induced fading probably won't be the determining death factor in the print life equation.

I hope that was a jest, but in case not please let me clarify.  My "elitist" concern was directed at Jon's "some people can't tell the difference" and someone else's (don't remember who) "good enough" remarks.  These can be interpreted as snide put downs, especially by beginners who often lurk in the forum, afraid to ask questions for fear of looking stupid or whatever (there are lots of them - I know because they often email me with questions and state that they are afraid to ask in public).  My concern, as I said before, is that the forum remain a welcoming and friendly place for everyone.  Those kinds of remarks hurt, they don't enlighten.

The elitist comment was not directed at you.  My only objection to your remarks was the use of "sucks" (as a complete dismissal of a widely popular process), which really surprised me because all these years you (along with Paul and Ernst as respected senior members) have been models of polite respect for all people and the various processes discussed here.  You have often been the moderate tone that soothed inflamed passions with humor and tact.  

Your printing skills are legendary and it is silly to infer that any mention of them is not permitted.  If your above remark was a jest it was not even a good one.  You aren't the sarcastic type...this isn't like you and it makes me worry.  Are you feeling ok?   You represent the upper end of the printer's art.  We need your example to light the way and teach us what is possible.  

I learned a lot from Bruce's posts re your work, especially the one that described the special processes you used on that custom job.  That's great stuff to read here.  It's the kind of thing that can inspire people to aspire to higher goals.  Remarks that imply that "some people aren't good enough" are not appropriate.  I hope this clarifies the issue.

It's been an interesting read, including between the lines.

The march of technology is inevitable.  It was obvious when K3 printing was introduced that the need for dedicated B&W had just been radically reduced.  The message volume of this list reflects that.  But there will always be those of us who just like to do something different, push the envelope, and beat -- at least in some parameters -- the big companies at a fraction of their costs. 

B&W photography will survive and thrive.  And technology will not replace artistic or creative talents.  Having the machinery to make good B&W has little to do with making a compelling image.

Clayton, 

That was me that described Tyler's methodology of custom mixing inksets for a particular portfolio and he's been doing this for many years in many different combination. I have seen dozens of his best works over the years and they are NOT comparable to Epson solutions. They are certainly not for everyone in this world, but they are to many.

When Tyler stated that ABW "sucks", he was describing HIS visceral response to them when compared to what HE sees as a higher level of tonal and hue rendition. That's HIS opinion from HIS experience and he's earned that right to state it. It is still a free country and we are still entitled to these opinions. Some painters feel that acryic paints "suck" and that is their opinion and their right. I feel that type C prints suck and that's my opinion (Andreas Gursky disagrees and sells his prints for hundreds of thousands of dollars).  We are NOT all of the same mind and taste. Thank God.

Yup,

They are in test and will appear in the AaI&A database at the 10 megalux hour mark in another few weeks. Stay tuned! 

Of the many challenges to this type of work, getting good representative fully randomized samples for testing takes considerable time and effort. But that was part of the method to my madness when I created the  AaI&A membership and sample submission concept...i.e. that we would be able to get true random replicates from end-users and that the replicates, at least for popular and important processes, would get tested as well. Your recent sample submissions show the concept is working!

I know Jon has concerns that this first sample of K6 Neutral on HN photo Rag now in test may have some production related batch issues and that newer K6 neutral and/or Selenium ink batches may provide a potentially better outcome.  No problem, we keep testing, and we keep working towards a good average megalux hour rating for the different tints (neutral, selenium, special editions, etc.) because these are all beautiful, historically significant examples in this era of digital print making.  I want the museums and archives community to have very good data on how to take care of them indefinitely.

Yes, thank you for sharing that link. I'm well aware of the work and contributed some of my own research to these IPI image permanence models.  This is a good example where in certain circumstances one can combine some parametric terms (i.e. in this case temperature and humidity), but there are plenty of caveats. In this research, IPI was tracking temperature and humidity effects on chromogenic color dyes and cellulose acetate degradation, two significant thermal degradation processes in traditional film photography where the temperature effect be modeled very nicely by the arrhenius equation and where the relative humidity level contributes linearly to the reaction rate, so the humidity effect can be rolled into the overall rate calculation. Thus, this research by IPI and others is very nice information to have when looking at environmental storage conditions for traditional photographic prints and films.  However, humidity effects like the humidity-induced dye diffusion in inkjet prints don't fit that model, so they require different testing methodologies and different environmental models to evaluate correctly. I myself and other colleagues are actively engaged in these new research efforts, but it does feel overwhelming much of the time!

I started AaI&A with a mind to overhaul the light fade testing protocols for digital print media first because it was sorely needed, and because it was the most inexpensive testing protocol to get set up and running at my new company.  That said, if membership ranks grow, I will try to implement other new testing protocols as well...temperature, humidity, gas fading, physical properties testing, etc. All it takes is time and money!

No way.  It takes talented, knowledgeable people as well.  Don't sell yourself short.

On a related subject, Jon wrote:

They are both, of course, very important factors for, probably, most of us, and they are appropriate topics for a technically oriented forum like this one.  


As to carbon, it's just a benchmark that has strong historic and broad testing support.  All else being equal, I think an art buyer will prefer the more stable medium.  It may not always be the best, and I may move on to something else.
 

Clearly the AaI&A tests have injected a lot in information relating to lightfastness into the field, and this is thread is, in part, the field reacting to it.  


Also, the issue of how many nozzles or ink positions are needed for different levels of smoothness is an issue that is behind some of what is being debated, and it's a legitimate issue.  I'm hoping my 7800 can print a smooth glossy MIS PK, LK, & LLK carbon image for this Elverhoj museum exhibit I'm doing, but I'm holding my breath.  My fear of microbanding goes down when I have more channels.  The HP PK + LK and LLK dilutions I had in those three 7800 slots did rather well, so I'm hoping.

Yes, although it helps to have a calibrated monitor, and even then the monochrome target pushes the limits of typical display technology, but nonetheless, I felt that resaonably accurate colorimetric reproduction of the fading results in the test reports would be helpful for everyone including myself. I miss that confirmation in the numbers that we get from the industry-sponsored tests.

What percentage is Wilhelm using to stop the test and declare it an end point. I still don't understand that.
> 

As I noted earlier in my previous remarks. the WIR 3.0 densitometric criteria set has numerous individual endpoints. The one that triggers first is the limiting factor that stops the test. However, merely testing for the limiting weakest colors can be misleading when it comes to total overall performance, so both weakest colors and average overall response should be evaluated in any thorough test.  This is a basic testing principle that so far been lost on many of the researchers in the field, ie. the notion that the system's weakest colors may not even exist in some image content, so we need to test for more than just the limit factor and express the total system rating as an exposure range rather than a single value.  

I actually misspoke earlier by saying there were 13 individual endpoint criteria in the WIR endpoint criteria set. Actually, it's 17, and you can get the itemized list here:

http://cool.conservation-us.org/coolaic/sg/emg/library/pdf/wilhelm/wilhelm_paper_feb_2002.pdf

Also, bear in mind that when it comes to monochrome print testing the number of relevant patches in the WIR test boils down to just three: media white point, 0.60 density neutral, and 1.0 density neutral. No full tone scale to exercise the blends nor any evaluation of dmax.  Recall that the original test design was for chromogenic color prints. One can infer the behavior of the whole tone scale by tracking just these few patches when evaluating traditional chromogenic color prints like Kodak Edge or Fuji Crystal Archive. Not so with modern inkjet which is why I concluded a completely new test design was needed. And hence....the I* metric and method was conceived, and AaI&A became the vehicle to get the new testing started.

Yikes, this thread has gotten so long, I'm having a hard time following all the branches.
I think its time for me to finish!

Anyway, it makes it difficult to compare the numbers for some of the B&W ink sets discussed here to Wilhelm's numbers for OEM inks.

WIR describes the endpoint of the test as "easily noticeable fade". To understand just how easy is easy and where these densitometric criteria go wrong with modern digital printing media, one needs to study the WIR 3.0 "visually weighted" endpoint criteria set which has 13 different threshold values.  Unfortunately, even if you take the time to understand how the ratings are calculated, the determining threshold factor is not published, so we don't know how the sprint sample is actually failing. The specific failure mode can have significant bearing on what system is best for a particular image. For example, a print that tends to show highlight yellowing (e.g., loss of optical brightener activity) would be more problematic for the white dress in a bridal portrait, not nearly so visually apparent in a dark and brooding landscape scene.

Thus, the 18.5 year AaI&A prediction at that light level is on the "WIR display time scale", but it definitely does not use the WIR densitometric criteria set to establish the amount of fade which occurred in test up to that point. The AaI&A Conservation Display ratings are based on "little or no noticeable" fading rather than "easily noticeable" fading, and they use a colorimetric rather than densitometric model for judging changes in image color and tonal appearance. Thus, the apparent disparity in ratings between AaI&A and other testing labs is caused not so much by the basic accelerated nature of the testing, rather the overall criteria used to define how the scores are achieved.

I can assure you that the types of hue and tonal nuances that are being debated between ABW and other monochrome inkjet printing methods in this forum are way too subtle to have any meaningful impact on a consumer-oriented "easily noticeable" fade rating. Thus, "easily noticeable fade" is, IMHO, too liberal a fading endpoint for fine art, but it's a totally valid goal to evaluate how a print is faring in mid-to late stages of deterioration. Because systems often fade non linearly, early stage fading may not be a good indicator of late stage deterioration and vice versa. Full system characterization needs at least three points to define the fading curve which is why AaI&A reports results at multiple exposure intervals and doesn't stop the tests when the AaI&A conservation display limits are reached. The AaI&A conservation display ratings estimate early stage fading performance only.

As others have eloquently said in this forum, the artist should first and foremost choose a process that imparts the aesthetic he or she visualizes for the created image. I've seen beautiful ABW prints, and I've seen exquisite B&W inkjet prints made with single channel, three channel, four channel, on up to seven channel monochrome ink sets,  but in each instance the artist made intelligent choices in image selection, image edits, ink, paper, coatings, etc.   Sometimes, the best choice involves a compromise in print permanence, but sometimes the best choice also happens to be highly durable as well.  We can certainly ignore print permanence testing and lull ourselves into a false belief that if it's a "pigment print" it must be "archival" (whatever that means), or we can take the time to discover the print durability strengths and weakness of our chosen processes. Adding print permanence information to the list of variables that should concern the artist helps to cut the bull$*#& and to choose wisely... even if the final choice is to use a fragile but aesthetically beautiful process.

I had a wonderful student intern from University of Delaware Art Conservation program two summers ago. Worked out great. I didn't find one last summer, but I wasn't trying hard enough. I'm sure some college student would have enjoyed the opportunity....free room and board and a summer in the Berkshires! Sorry, no salary yet, but in the future hopefully that would be part of it as well.

Know anyone who might be interested for this summer? It's wide open :-) I could really use someone interested in the library and archives field, as I've got plenty of cataloging now to do for all those wonderful print donations AaI&A members are sending me along with their test samples. That's the Archives part of the AaI&A mission.

thanks,
Mark

Thanks, I took a quick look and didn't see any library science or conservation related fields to fill out on the template driven job listing menu, but I will spend some more time tonight and see if I can select a more fitting menu to list a position here at AaI&A for the summer. Closest I got was studio-photography intern, but as much as I love photography, the position would not be about assisting a photographer!

Nevertheless, it does seem like an excellent resource, so thanks for the link.

Re: [Digital BW] ABW is Walmart Special

2010-04-10 by dtphotog

John, Jon, (and Roy Harrington too),

I don't often post here, yet I couldn't help respond at this point in this thread.  I am currently printing with ABW (and still learning how to make it do what I want) but I would also love to investigate some of the more specialized printing approaches being discussed here.  The problem is that I use an Epson 7900.  QTR doesn't support it and says it won't be able to because of Epson constraints, yet ColorByte has been able to (finally) release a version of ImagePrint that does. (My simple test showed that IP8 does produce very slightly better screening than the Epson driver and ABW.) And as far as I know, it's not possible to consider something like K6/K7 in a 7900 (assuming I'd actually want to do that).

The problem for me is that I would like to be able to take advantage of improvements in the core technology being released by the printer vendors (i.e. improved dot structure, paper handling, etc.), but this means giving up the option to experiment with other software (and especially) ink combinations.  So to me there is an interesting irony in that you can't explore these "improved" printing approaches using the latest printer technologies.  I'm fully aware of all the reasons for this, yet I'm still struck by how improvements in one aspect of making fine prints can actually torpedo your ability to make improvements in other areas.  I guess it comes down to having to make choices (and therefore compromises), as Jon said earlier in this thread.

I went into the Super Walmart the other day, up here in the burbs of Georgia to buy some soap, and low and behold there it was, the Super Walmart digital imaging center, complete with Epson 7880s, cranking out ABW prints by the thousands. I wish I were kidding but I'm afraid that IS what this HAS come to, right now, artistically created cheaper by the dozen "archival" pigment prints on Sommerset Enhanced.

Re: [Digital BW] ABW is Walmart Special

2010-04-10 by john

Dave,

I don't have any desire to open up this whole can of worms again because it has run its course as far as I'm concerned. But to answer a very, very good question you just asked....which wasn't answered yesterday.....

The one thing I would mention is that a lot of the frustration you see in the posts by those of us who have been using "alternative" approaches to monochrome inkjet through mixing our own inksets whether Piezography, MIS, Media Street, or whatever, see ourselves running up against the wall of being locked out of all future piezo type printers, possibly forever. It started with desktops and moved to the large format printers like the 9900 and 7900 now. They like have an electrically coded chastity belt on them now. It may very well put an end to a whole era of openness that has made user groups like this one possible. When all the future inkjet output will be from giant OEM companies alone, something will be missing. That is a very real possibility. Some people won't miss it, others will. I will.

Unfortunately this paranoia on the part of Epson to lock out experimental black and white inks that CAN do things they can't, has also recently included the locking out of some of the finest software capability ever created to work with these inks (including OEM inks) such as Studio Print and QTR, and whats next Qimage and Bauhau rips to? 

In my opinion, and this is MY opinion, one of the reasons you sense a heightened degree of sarcasm on the part of many of us using these large format systems for alternative processes is that Roy Harrington's and Jon Cone's (much earlier) genuine love of this medium and his totally unselfish devotion to upping the standards for black and white inkjet imaging for over a decade (when Epson bw indeed did suck 100%) made the demand for ABW surface in the first place. Again, just my opinion and you don't have to agree with me. But I was there using the horrible Lyson quads and everything else trying to make something happen at great expense and frustration because there WAS no Epson solution, none. Others were using neutralized carbon inks that ended up in museums all over the world way before Epson even offered a single light black to work with in the K2 inkset. Yes, that was then and this is now.

Now that Epson's improvements to black and white output is decent enough for many to do great things with it, why are they still so paranoid about some little guy like Roy Harrington continuing to offer great software that can do things they can't do or won't do in the same way for those who need it? To me Roy Harrington is a hero, not a reckless vigilante.

I never heard an answer to that question, and this attitude is one of the reasons I moved on the HPZ series for my color work, and a lot of black and white work on glossy media as well. At least HP doesn't freak out when we don't use HP media and even offers media presets to use papers they don't sell. In the world of mega photography, at least that is a start. But without the small independent rebel tweaking around the parameters of the mass products, everything ends up looking the same. Again, just my opinion.

In his discussion of "Kodak Years" vs. "Wilhelm Years", Mark uses the word "assume" with respect to ambient light levels. That needs some explanation. Kodak chose its 120 lux light level (for a 12 hour "day"), not by just assuming that value, but by doing the largest study of its kind ever undertaken, measuring light levels (along with temperature, humidity and ozone) continuously extended periods of time in a statistically-chosen sample homes throughout the world. The results from these millions of measurements were published in a referred, scientific journal so that other photographic scientists would know why, how, and where the data were collected. No one else has done this. Others have chosen their assumed lux level on the basis of single-reading spot measurements (which can vary by a factor of 1000 during the day) and without seasonality effects, which can also induce large variations. 

Kodak's data was backed up by actually hanging prints and film in a subset of real homes, in the places people really do hang their photographs, for up to 10 years and measuring their fade. The results were consistent with the instrument data. Again, no one else has done and published such results. 

It is definitely true that light levels vary in and between homes by very large amounts during the course of a day and a year. But because of the reciprocity principle, what's important is the average intensity that the prints see. In the Kodak study, that was 137 lux at what's called the 90th percentile (that means that 90% of the measurements were at or below that value), thus 120 lux as an average is actually quite conservative for the home.   

Why is it important to use the best value (for light or anything) that you can determine? Because there are other factors involved in degrading a print. As mentioned above, there's heat, humidity, and pollutants (largely ozone). If you assume too large a value for ambient light, for example, you could predict that a product would be done-in by light fade when really ozone-induced fade would kill it first in a normal home environment. This might cause you to choose the product that would fade faster in a home environment over one that could last longer. Like in so many of life's other endeavors, balance is important.

It's also important to note that these discussions relate to home environments. Museums, galleries, offices, commercial displays are all different. For "archival" prints stored in the dark, heat, not light, is by far the more important factor (and over 90% of prints spend most of their time in the dark). For an outdoor signboard, the light level could be 50,000 lux and heat would play little role. Further, homes, museums, and offices have different types of light, not just different levels (the Kodak study was also the first to use recording spectrophotometers to measure that as well), which can make a big difference in light-induced fade rates.

One way to get around a few (but far from all) of these issues is to abandon the pretense of predicting lifetimes and use something like megalux-hours of light to achieve a specified degree of fade. Aardenburg does this. But you still have to contend with what that level of fade should be, what metric you use for measuring it, what kind of light you're assuming, and how you balance the other three factors of heat, humidity, and pollutants. 

Further, you need to be able to show that whatever sort of fade you measure with your instruments correlates to what we see with our eye-brain combination, a very tricky process with many pitfalls (think "optical illusions", but ones that occur in real life). This requires that whatever model you choose to assess accelerated fading should be checked by psychophysical studies. An awful lot of the claims made for fade ratings have not been so verified. 

Bottom line: this is a tough business. Take what you read with a handful of salt. Be suspicious of missing data. And think how you are likely to use your print and choose its attributes accordingly.

That's very interesting stuff and I'll print that out for my files too. Kodak has done a lot of research in this area as has Fuji, who made a much better product by the way.

However, the fact remains. I do art prints for a living and I have a lot of large expensive inkjet prints out there, and before that Cibachromes, that are hanging in peoples homes by large windows where they look great. I also have done installation shows that are on permanent display in airports and big office buildings where these prints are under skylights and also by large banks of windows. 

In all of these cases the illumination hitting them is WELL in excess of 450 lux, many days, much less 120 lux. So, in the real world, as Mark has pointed out a million times we have no control over these factors and the more conservative and detailed the analysis the better. That's the way I look at it.

This is a bit like health food stores. My vegan friends have difficulty understanding it when I claim that the biggest gift health food stores have given America is that we can now buy tofu and organic produce is the supermarket. I assume you can all appreciate the analogy: yes the early pioneers of B&W gave us prints we will cherish (I have a couple of Tyler's I would be unwilling to part with, and one of Joe Holmes)... But in the long run it's the fact that it is now possible for a wide range of users to make low metamerism, long life black and white prints that is the biggest gift.

Kodak chose its 120 lux light level (for a 12 hour "day"), not by just assuming that value, but by doing the largest study of its kind ever undertaken, measuring light levels (along with temperature, humidity and ozone) continuously extended periods of time in a statistically-chosen sample homes throughout the world. The results from these millions of measurements were published in a referred, scientific journal so that other photographic scientists would know why, how, and where the data were collected. No one else has done this. Others have chosen their assumed lux level on the basis of single-reading spot measurements (which can vary by a factor of 1000 during the day) and without seasonality effects, which can also induce large variations. 


Jon ["jakapecki"], you are a very smart guy, and when we were both involved with the ISO committee's work on a new light fade testing standard, I took many of your comments and criticisms about the WIR 450 lux level to heart. They definitely influenced how I set up my own light fade testing protocols at AaI&A.  If you can still pass along this information to your colleagues representing Kodak on the ISO committee, I humbly suggest that AaI&A has offered WIR, Kodak, and the ISO committee a logical way out of this long standing pissing contest about who's average light level is the better one to use as  a "normative" light level in the real world.  Simply report megalux hours of exposure rather than "extrapolated years on display", provide an appropriate exposure dose-to-display environment conversion table (as AaI&A has done), and this absurd debate is resolved.  As for trying to integrate all the possible additional print degradation pathways together into a one-size-fits-all print life prediction, well, you and I both know that's a fool's game.

I'm always delighted to read the comments of Mark McCormick-Goodhart who has over the years provided archivists with a number of highly innovative tools both for preserving images and for measuring those efforts at preservation. Knowing Mark's passion for this, I am confident that Aardenburg will continue that tradition of service to the imaging community.

Perhaps I was not direct enough in my comment ("abandoning the pretense of predicting lifetimes")to indicate that as an imaging scientist I think megalux hours (or some similar metric) is indeed a better way of providing imformation on light stability than years. 

None the less I also contend that it alone does not solve all or even most of the problems related to characterizing image stability or even just light stability. I mentioned some of the confounding variables in my earlier post. This is not trivial, and I have seen real world products where, for example, the choice of a light source for testing provided numbers that were meaningless in actual use evironments. (Fortunately, I have not yet seen manufacturers building to the test--which one could well do.)    

And even though we cannot find a useful way of integrating light, heat, humidity and pollutant degradation into one factor (something I have never suggested in my post or elsewhere), this does not mean that we can afford to ignore them. 

One of the other posters to this thread suggested that he would rather assume very high home light levels as a conservative measure. Fine. Assume 50,000 lux. Then you will almost guarantee that any other degredation process will be more likely to be the pratical cause of image loss in the real world. To repeat myself from the earlier post, balance as it occurs in user environments is vitally  important. 

One last comment. I don't want to sound elitist here, but the folks who post to this group understand a megalux hours metric--or if they don't, they will take the trouble to learn about it when it is called to their attention because they care about these things. 

Most consumers, however, neither understand nor want to learn about lux or ppm ozone or Arrhenius plots. They're understandably busy with other things. They want to know "How Long Will It Last" and they want that answer in years. Is it better to provide them with a number that has a large measure of uncertainty built in (perhaps better, a range)or to simply say nothing and provide no guidance at all. This is a debate that imaging scientists, conservators, and photographers have had for years (I commend to all a recent excellent article by Peter Mason of Torrey Pines Research on this issue--see their website). "Consumer Reports" and Wilhelm Imaging Research have done quite well by choosing the first alternative. Aardenburg serves a different audience. 

However, if we do choose to provide a years metric for some users, then we must base on the the best scientific data we can gather, not guesses or assumptions or personal beliefs. On that point, I won't back down.

The audience of dedicated printmakers and collectors I have chosen to reach out to with my research is no doubt a decidedly different demographic than the typical consumer of photofinished prints, but that doesn't mean the typical consumer is better served by the whole "how long will it last" argument. For many years (up to and including the last time we saw each other, Jon), I accepted that whole argument that "consumers need a simple soundbite" and believed a reply to that question expressed in years was the way the "experts" were supposed to answer.  However, it is now painfully clear to me that consumers take these answers at face value and it unfortunately leaves most of them with the false notion that they play no role in the outcome. The "life" is inherent in the object. That's a huge problem with ratings expressed in years.  I have thus come to categorically reject permanence ratings based on "years of life". 

If you want to keep it simple, then give consumers five star ratings, 1-10 rank level scores or the like, for individually rated factors like heat, light, humidity, gas fading, and lightfastness that can be correlated to a rigorous standardized set of tests. But years of life? Even the most fugitive  and fragile systems can last hundreds of years when moderate efforts are made to preserve them.  That reality totally negates the significance of ratings expressed in terms of years. 160+ year old copies of Fox Talbot's "Pencil of Nature" salted paper prints survive to this day because people recognized the historic value of the work early on and figured out what Talbot's early salted paper prints' relative print permanence strengths and weaknesses were. In terms of light fastness, these vintage prints wouldn't even make the 5 megalux hour mark (20 years on display using the Kodak 120lux/12hr per day estimate)  when applying any rational criterion for fade and discoloration because these prints were made before sodium thiosulfate fixing procedures were discovered. They are incredibly light sensitive to this day, but collectors quickly figured that out and hence do not display them year after year at 120 Lux for 12 hours per day.

My point is that with reasonable care, any modern photographic print can easily last well over a century. So, shouldn't we just tell that to the public and leave it at that? Hey folks,  buy any print you like, even one printed with fugitive dyes on ordinary newspaper pulp, treat it with reasonable care. and it will survive well over a century! That's no lie, and it's an easy soundbite to remember!  But it doesn't tell you what factors will cause the print to fail prematurely and what steps you need to take to ensure "reasonable" care.  For that we need the rigorous testing and more intelligent ways of communicating the results to the public.

I admit I don't have all the answers, but the sooner the imaging industry gets past this grossly oversimplified notion of display life for print permanence ratings and moves to ratings that address durability issues on a more honest scoring basis, the sooner we will have meaningful advice to tell the consumer about caring for the specific print processes that they choose to buy.

End of rant...but definitely in the spirit of this thread for sure!

Promoting AArdenburg?

2010-04-11 by Gary

Mark,

Just a thought... it would be interesting if you could post a few images on
your site of what the testing area looks like and or a U tube of the testing
process. I think it would be informative and interesting to see a few behind
the scenes looks of the actual  testing location. You may get some
additional exposure millage out the images. 

 

Keep up the good work!

 

Thanks,

Gary Wagner

I think that is a great idea, post a demo on U Tube and send that to every museum and major gallery in the world, and do that every month for a year. 

In regard to print fade protection, museums do have it together in this era and are very obsessed about low light levels. Often the levels are so low you can barely see the work, especially color.

The problem is 99% of the art work produced doesn't end up in those environments. It is better to build a monochrome solution inkset that lasts in real world conditions because that is exactly where most of it will end up. I know, I see it every week at peoples homes. And it is very true that the OEM approaches are getting quite good at that these days.

2010-04-11 by jakapecki

I do not prefer a years lifetime metric, even in the consumer sphere, because it does not convey the uncertainty involved. (This is especially true when one sees numbers like "97 years" which imply a precision--not 96, not 98--that is truly fictional.)

But I also recognize that megalux hours or ppb-hours or the like are not going to help the consumer, as valuable as they may be for those truly interested in print preservation. 

My inclination is towards a range for each of the four important factors (heat, light, and pollutants--humidity requires something else) as star system without further qualification fails to convey what Mark said--that most name-brand products will last at least several generations under normal use conditions.    

But if we think we can couple those star ratings (for each factor, of course) to an explanation that educates the consumer as to more than just their relative meaning, then--hey--I'm OK with that. (A good portion of my career has been spent working to help consumers and others understand this sort of stuff.) 
       
Basically, I think there is little disagreement between Mark and me over this, and instead we can move on to arguing over test procedures, light sources, endpoints, meassurement protocols, and the like, where there are still many problems unsolved over which reasonable and passionate people can disagree.

Well, my test equipment isn't very pretty and neither am I, so my adventures into video celebrity status will have to be undertaken with deliberate measure! That said, it's what's under the hood that counts, for both men and machines, so in that respect I'm comfortable with sharing my methods freely with others. 

Anyway, I do take your suggestion to heart and have already had my web programmer get the AaI&A website website ready for some video tutorials.  However, don't look for Hollywood production values. It will be pretty basic stuff.  I think my first tutorial needs to be a good illustrated discussion of "What are Megalux hours, anyway?", i.e. how the diversity of lighting in the real world impacts print fading, how it is measured, and how the light exposure  accumulates over the years to add up to the kinds of megalux hour exposure doses AaI&A reports in the light fade database. I also need a video tutorial to help people better understand how to read the AaI&A test reports. Some have criticized my reports as being too complicated, but once people take the time to learn some of the basic concepts, it's all pretty straight-forward.

So, I'm with you in principle on this video education/promotion work.

I would still like to see an image of what the prints look like being

Mark,

A few video's is a great idea. I would not host them on your website just host them on youtube and make sure you use keyword rich titles, description and tags which will all help your SEO. Youtube will also be another place that people can find out about you. Once you have the video youtube you just host a player window that is real basic code you get from the youtube site after you select the size and color options. You can see an example on my site for our assembly video:

Re: [Digital BW] Re: Now Current status of Iris B&W printing

2010-04-14 by Brubaker family

For forum readers, I am embarrassed to note that my listing of the photographer's name and web site in my original post were not correct.  He is Richard Bickle, and the web site is richardbicklephotography.com.
Jon,
Thank you for your reply.
It is very interesting to learn about these technical details of the Iris process.  I am inferring from your description that the Unitone and Digital Platinum were dye inks?  Otherwise it doesn't seem that the continuous tone output of the layering of the dots would work, ie. the continuous tone effect requires the translucency of dye inks and would not be possible with pigment inks.  Other than the anecdotal data on the print you have had on your wall for 19 years, is there any data on the longevity of the Unitone prints similar to the current data on pigment inks?  (Maybe you could send a Unitone print to Mark Ardenberg for his testing?)
If the prints I saw used the Unitone inks, then it sounds like that process contributes to the perceived lack of grain that even the 30 X 40 prints show.  I infer that an alternate process, particularly pigment inks, would show more grain?  I am sure that each step of Ron and his printer's process is maximized to minimize the perceived grain.
It also sounds like the paper used for these prints is probably a non-inkjet coated paper?
Would it be technically possible to produce a Unitone-like effect with the Epson dye inks overlaying each other rather than being dithered?  That would be interesting to see.
If you have seen any samples of Tyler's best B&W pigment ink prints, how would you compare the Unitone prints to them?
I look forward to your replies.

      The printmaker in Atlanta would probably be Jamie Cook unless he sold his operation, and the process is ConeTech Unitone, something I designed about 1992. Jamie Cook was one of the first victims which I sold an IRIS 3047 printer to - and he opted to take my methodology training and buy ConeTech software that I developed to make b&w prints using color inks. I was the Development Partner for Fine Arts at the time with IRIS Graphics, Inc.



Unlike Epson ABW which develops density through three shades of black and uses color inks adjacent to black dots to make tone, the ConeTech UnitTone process is quite different and relies on a system of lookup tables to precisely place the color dots of ink under the black dots of ink rather than adjacent to them in the normal IRIS dithering process which was called matrixing.



The IRIS printer forms 31 distinctly different dot sizes comprised of between 1 and 31 droplets of ink. The 31 is theoretical but was actually obtainable via a number of lookup tables working in harmony. The basics of Unitone are to define a tone made of mixing cyan, magenta, yellow and black ink. I predefined a number of tones between warm and cool. This becomes one lookup table for the recipe of inks to make a "tone". 



You can see a picture of the possible tones created with my Unitone process using color inks here:



http://www.piezogra phy.com/PiezoPre ss/wp-content/ uploads/2010/ 03/unitone. jpg



In terms of data sent to the printer - for every density location, a certain amount of cyan, magenta, and yellow drops of ink are placed immediately under a black dot of ink and in that precise order according to the Unitone recipe. A Photoshop routine is used in conjunction with the lookup tables to prepare the file, because to fill in the spaces left by missing matrix dots of cyan, magenta and yellow, they too are produced by smaller drops of cyan, magenta and yellow hiding under black, produced from CMY image data produced in the Photoshop routine. The end result of UniTone with a strong loupe does not show the tell-tale IRIS matrix and looks virtually continuous tone - and more importantly, you can not see any ink color other than the chosen UniTone. Not a stray cyan, magenta or yellow dot. Every black dot is a UniTone dot.



I have a UniTone print hanging on my own foyer wall that I printed 19 years ago that remains very fresh to this day. The black ink acting to support greatly the more fugitive nature of the color inks. The software was in DOS - and to this day runs on very old versions of Windows by those who opt to keep my system alive. The PC is an older architecture that can support the printer interface cable. This is very archaic technology by today's standards. But at one point more than 40 printers in the USA produced Unitone prints in the mid-1990s. Most went out of business because of the proliferation of Epson printers allowing artists to no longer need the services of fine art service bureaus.



I still run one. They are exceedingly rare and the parts supply is maintained now by ITNH. They're crazy expensive to maintain. But sometimes they print black & white like no other process. I am producing Zana Briski's bug prints right now with my IRIS. Nothing else compares. I'm using UniTone for the project.



DigitalPlatinum was a quad black ink system tied in with media profiles. I believe that this is the first quad black system of inks and profiles ever designed. This one is more complex in some ways, relying on dot placement in conjunction with a variable tone process of inks. Maybe this will help the mad scientists here. Shade 1 was black, but shade 2 and shade 3 had the same density (middle gray) and were used to modulate the mid-tones into several possible tones depending upon how much of one was used in comparison to the other. One of these two inks was greenish/brownish, one colder/brownish. The forth bottle was in two options and used to influence the highlight split. It was the light gray and you would change it out depending upon the effect like how paintings are glazed. One was neutral and the other very warm.



You can see a picture of a replicant of Ziatype printing that I could produce with DigitalPlatinum here:



http://www.piezogra phy.com/PiezoPre ss/wp-content/ uploads/2010/ 03/weese2- 900.jpg



The photographer is Carl Weese and the split toning imitates the printing out process which gets warmer with greater exposure. But it could also imitate many other styles of platinum printing quite different than this. I never licensed it preferring to keep it only for my studio.



Diana Michener's Solitaire exhibition at Pace McGill was DigitalPlatinum - I think I printed it in 1997. It had a much more selenium look to it and was produced on extremely delicate japanese paper. Some of the software I made to do the Ashes and Snow prints for Gregory Colbert came out of DigitalPlatinum. That took 11 inks and yet was in no way as delicate as DigitalPlatinum with 4 inks.



I really do not believe that any other inkjet process will ever replicate the beauty of the surface of this type of printing - yet it also fits into the category of something felt and perceived rather than some data that can be understood. The process of 31 sized variable dots of ink is a very powerful asset to making photographic prints on uncoated papers. But, the majority of IRIS printmakers used coated papers and Scitex software and these types of IRIS prints are more ordinary looking and perhaps lower in visual quality to Epson 7000 color prints.

> It is very interesting to learn about these technical details of the Iris process. I am inferring from your description that the Unitone and Digital Platinum were dye inks? 

Yes correct.

> Otherwise it doesn't seem that the continuous tone output of the layering of the dots would work, ie. the continuous tone effect requires the translucency of dye inks and would not be possible with pigment inks. 

No. I've layered pigment ink on other pigment inks with wonderful transluscent effect. Pigment today is so small that it does not behave like an opaque material as much as it does as a dense material.

> Other than the anecdotal data on the print you have had on your wall for 19 years, is there any data on the longevity of the Unitone prints similar to the current data on pigment inks? 

The original Unitone prints were made from ConeTech WGFA (Wide Gamut Fine Art) inks which WIR tested in 1994 at more than 24 years, which was greater than Cibachrome. I know that 24 does not seem like a long time - but color chemical photography is not very long lived. Cibachrome gave a 200 year warranty for marketing. The real results are shorter.  But, WIR did not test Unitone - only color patches for the WGFA inks that were used to make Unitone. I do not think WIR had yet created a test target for monochrome back then.


> (Maybe you could send a Unitone print to Mark Ardenberg for his testing?)

I could possibly make a Unitone Print for Mark using the American Inkjet Pinnacle Gold inks. I no longer make IRIS inks.

> If the prints I saw used the Unitone inks, then it sounds like that process contributes to the perceived lack of grain that even the 30 X 40 prints show.  I infer that an alternate process, particularly pigment inks, would show more grain? I am sure that each step of Ron and his printer's process is maximized to minimize the perceived grain.

Piezography prints do not show dots, unless you mean film grain?  Grain is a function of scanning. Unitone would show grain if grain was present. But, IRIS is only 300dpi, sometimes only 150dpi if the 2x replication option is used. So a high resolution scan to make a 30x40 at 150ppi might not resolve grain. Most printers printed at 150ppi as hard as that is to believe. The perceived resolution at 150ppi is about 1000ppi in comparative printer systems.  

> It also sounds like the paper used for these prints is probably a non-inkjet coated paper?

Jamie uses Somerset Velvet for as long as I knew. Somerset Velvet for IRIS is uncoated.

> Would it be technically possible to produce a Unitone-like effect with the Epson dye inks overlaying each other rather than being dithered? That would be interesting to see.

The Ashes and Snow prints I produced for Gregory Colbert have inks that overlay each other. Without going into detail about how I produced the exhibitions, the process did involve layering of ink.  However, have you not seen a Piezography print before? There is no visible dot even with a loupe.  You should join in on the R1800 / R1900 beta for the new Piezography concept if you haven't seen Piezography printing before. I posted for volunteers a few days ago and there are still a few slots open.

> If you have seen any samples of Tyler's best B&W pigment ink prints, how would you compare the Unitone prints to them?

Tyler could take an impact printer, experiment with it for a few weeks, and then knock out masterpieces... so I won't compare with him and his use of the Piezography system.

I can tell you that PiezographyBW compared with Unitone. And that DigitalPlatinum compared to Piezography K7.

Mike,

I visited the link you left, just one more correction:

http://richardbickelphotography.com/

But, I know this work and I have his book. I happen to love Apalachicola River oysters. Even been there to eat them. I'm only guessing that he printed with Jamie in Atlanta. And Unitone by what you described. John Dean says Jamie is out of IRIS now. I thought I saw Jamie within the last year and he said he still had the IRIS at that time. I don't think there is another fine art Iris in Atlanta.

In any event, I love this photographer's work and love that part of Florida. Just an hour or so NW is Seaside/Watercolor - a complete contrast.

I was born in South Florida. My mother is English and my father who is American moved to Florida just after WWII. Coconut Grove was not unlike Apalachicola when I was growing up. Even Miami was sleepy time back in the 50s 60s. But Apalachicola is definitely old Florida. The oysters sweeter then the parishes outside New Orleans.

When I was there his gallery was not open. I would have liked to have met him. Thanks for sharing the work.

Hi Paul,
Did you have any trouble feeding this paper?
It is pretty thick.
Thanks

The Epson Hot Press Natural using Eboni Black Only in an Epson 1400 is about
dead neutral.  The 50% Lab B is less than one unit above the paper base Lab
B.

Here is a QTR profile for the 1400 Epson Hot Press Eboni Black Only:

I just tried to feed a piece in through the normal paper feed slot, using
the paper feed button, and it fed fine (with a slight hand assist).

I think with the 1800 3MK, it'll be a terrific paper.

Never mind.
It feeds just fine.
