Digital BW, The Print

MIS now has the generic base mixes, including that for the dyes, pre-mixed on its web site.  The prices look good. These are arranged by the mix -- C6a, b, and  c, as well as the dye mix.  Pint and gallon volumes are offered.

I think they should consider adding a biocide.  Both times I mixed the base
I ended up with some white mold growing in it after a couple of months.

I don't know what the variables are.  I've never had any biological activity.  I just use store bought distilled water.  The glycerol is 99.7% pure from San Jose Scientific.  I store the base in the usual relatively clear ink bottles in a room with 2 small windows.  They have been there for years now.  My daughter's 3.5 year old carbon-6 mix seems to be fine after that long a time in a CIS in a dorm room.

At the other extreme, I've been told commercial inks with biocides will sometimes grow algae in the CIS lines in Arizona sun.

I don't know why we get different results.  I used glycerol from the
Chemistry Store + distilled water.    The room the base is stored in is my
2nd story office, which is heated and air-conditioned like the rest of the
house.  There are two windows.  I don't know if the mixed ink in the
cartridges was affected.  As soon as I saw the mold in the clear base
solution, I took all of the cartridges out of the printer and installed
cartridges with storage solution till I can afford to mess with it again,
which might be quite awhile.

There is always a risk. Even a CIS for an Epson 5000 filled with the 
content of larger Epson dye carts gave trouble like that, white stuff in 
all the lines.

A copper or silver wire (silver solder too I guess) in the bottles may help.

We can send Paul a quantity of biocide that we use, but I would worry about it tinting the base as it is an amber color and thick similar to honey.  We have also not looked at how this would alter the overall performance of the base.

Storage and prep are very important when producing a base like this as everything must be clean to prevent biological contamination.  We are using a high grade 99.7% glycerol with distilled, deionized water mixed in our glass sealed mixing equipment to minimize risk.  It is also important to wash the bottles before transferring the ink as a little bit of dust can cause a lot of headaches.

Well, I used a clean mason jar and teflon bar on a magnetic stirrer to mix
up my batch, along with lab grade glycerol.  I used clean disposable
syringes to measures and add the inks.  This system is not closed, though,
and stuff in the air can get into it.  My photoflow was stored in my
basement darkroom, which can be a little damp, and so maybe this was the
problem.  I know that diluted photoflow solutions turn bad fairly soon in
my darkroom.

I still have the base:
http://i955.photobucket.com/albums/ae37/peterdesmidt/clear_base.jpg

I don't know if the mold grew in the cartridges, but I can't risk it, and I
probably shouldn't use the cartridges again, sigh.

And they're large funnel fill cartridges for a 4880.  Double sigh.


[Non-text portions of this message have been removed]

One factor that a chemist once mentioned to me was the varying quality of distilled water. This chemist worked in molecular biology and had standards that I assumed were way beyond what I would need.  At any rate, she recommended de-ionized or double distilled water.

I just double checked my old mostly empty bottles of generic base, some going back 4 years, and I don't see anything that looks like biological activity.  The only spots on them are splashed ink on the outside of the bottles.

As a precaution, of course, I would recommend people with funnel fill carts use black plastic or the like around them to cut the light.

If the use of the base is for Eboni dilution, then those concerned ought to buy the pre-mixed Eboni-6.

This almost looks like precipitation, is it floating or does it settle?  Would it be possible for us to get a sample as we can culture it to see if it is biological, and get an idea of what it is.

Also, which varient of the base is pictured?

Hi,

It settles.  It's Paul's standard base for Carbon-6 for use in the bigger
printers.  Sure, I'd be happy to send you a sample.  Just let me know where
to send it to and how much of it you'd need.

One thing an old pharmacist (they used to be chemists, right?) once told 
me is to rinse whatever container you are going to use 3 times with the 
solution you will put in it.  I rinse jugs with dilute Clorox first, 
then let any fumes boil off three days before using the container.  
That's before the "3 rinse."

Another thing.  I do some nickel plating, so non-distilled water would 
create a sludge right away.  One warning I received was not to store the 
distilled water more than 6 months.  The plastic jugs are permeable to 
O2.  Heck, at .93/gal, buy some new.  LOL

I was curious as to whether it was C6a, C6b, or C6c as they have slightly different properties.

We would only need less than an ounce of the base with the white contamination.  If you are interested, please send it to

Hi Justin,

Sure, I'll send some off on Monday.  The base is C6b.

A clear fluid in a transparent bottle and a water treatment type UV lamp

This is reminding me of the conversation of a month or so ago regarding automatic vibration of ink to avoid settling. At the time, I'd sent a link to a tiny vibrating motor of the type used in cellphones. We've also heard of copper wires inserted into the cart as a biocide, and covering the cart itself with black plastic to avoid sunlight.

Perhaps all these can be wrapped up into a new product -- a sleeve that slipped onto the end clear/funnel carts, containing a vibration motor, a UV LED, a copper wire to be inserted into the air hole, a microcontroller with a scheduler, and a small battery to power it all, all enclosed in an opaque shell. While we're at it, it might as well monitor ink levels, temperature, and humidity...

Only half-seriously,

I missed this image.

In testing different blends, I saw some effects similar to this, but they were usually throughout the mix.  I think the literature refers to it as "clouding."  If the mix of co-solvents and surfactants isn't correct this can happen.  I've never had it happen to a mix that used the ratios, by weight, of the published formulas.

Paul
www.PaulRoark.com

It's been awhile since I mixed this.

My standard practice in mixing is to use my darkroom scale, which I use for
making my own developers.  It reads to .01 grams, and has been accurate
enough for measuring phenidone in developers.

Algae needs light.  Mold doesn't.  I don't know if it is mold, but it seems
unlikely to be algae.  (I run reef aquariums, and so I'm pretty familiar
with algae.)

UV-C does kill micro organisms. There are UV-C LEDs available. You would 
not use that for colored inks but on the clear base + water that is used 
and only at mixing time. If there is already mold in the ink it is 
actually to late to sterilise, the dampers will be clogged with dead 
micro organisms.

I did suggest to put older ink bags in an ultra-sonic bath to bring/keep 
the pigments in suspension. Not more.

Ernst-
You ARE the man!! I keep trying to remind myself to shake the pigment 
jars the day before I refill.

I have TWO ultrasonics here and didn't even think of that.  Thank you!

The non-moving carts on the new 3000 have me a little worried though.  
Guess I'll just have to print more.

Did the ink removed from the funnel fill carts contain any visible contamination?

Hi Justin,

I didn't remove any ink.  After I loaded a set of cleaning cartridges into
the printer, I put the ink filled cartridges on the shelf.  I can empty one
to see if there's any contamination.

With the above bases available at an acceptable price in the US and in 
Europe similar bases available from OCP, is it sensible to home brew the
