MIS UT2 Carbon prints very non-linear

MIS UT2 Carbon prints very non-linear

2006-01-14 by chwhitaker

I'm using MIS UT2 with my 1280, and I'm getting strange results on
tests I've done. I wasn't happy with the prints I'd made with the
Carbon curves, so I made a radial gradient with maximum black at the
center, and printed that. The results explain my unhappiness with my
previous prints. Take a look at
http://www.charles.whitaker.name/CarbonTestResults.jpg. This is on
Epson "Archival" Matte, with paper type = "Photo", no color
management, at 300 dpi.

I don't know if something is drastically wrong, or if I just need to
change some settings. Should I ever expect to print this gradient with
completely smooth transitions, or is some blocking in the shadows
inevitable? Thanks to whomever can help.

There is definitely something wrong.  The usual causes are bad nozzles or
wrong settings.  Check the Color Settings.  Be sure you're using Gray Gamma
2.2 and Adobe RGB (1998).  Be sure there is no other profile embedded in the
file.  If you're using CS2, in Print Preview, use No Color Management.  In
older setups, use "Same as Source."

Do you get good results with a grayscale file and "Color Controls" checked
in the driver?

Printers are not all identical.  There is the usual bell curve of
performances, and if yours is out on the ends of that curve, the canned
profiles/curves just will not work acceptably.  If you use a 21-step file to
test with that might tell me more about where the problem is.  I have test
files at http://home1.gte.net/res09aij/Test-files.htm.  There are also test
files there that you can use to be sure the inkset is correct -- or at least
close.

When all else fails, there are still ways to get the system going, but try
all of the above first.

Paul,

Thanks for your response. The inkset seems to be the problem. My purge
pattern matches your sample fairly closely, except for light magenta,
which is *much* darker than yours -- about as dark as magenta. I guess
this means my UT2 color cartridge has the wrong ink for light magenta
-- right? If so, what's the best way to present the problem to MIS?
Thanks again.

A quick followup to my previous response: I meant to say "light cyan"
and "cyan".

I'm not sure a too-dark LC would cause the problem you're having, but it's
possible.  Try printing an RGB 21-step test strip with only the red curve at
its default position, and the green and blue curves horizontal -- i.e., the
magenta and yellow inks turned off.  On the monitor the RGB image will be
cyan.  With No Color Adjustment selected in the driver, the ramp will show
if the LC is way to dark -- the ramp will be awful.  (If you don't know how
to make this curve, let me know and I'll send one off list.)

Paul,

When I leave red as is, and flatten green and blue, the step wedge
appears red on the monitor, not cyan. Can you send me the curve you
describe below? Thanks.

Finally got the curves you described. The results are at
http://www.charles.whitaker.name/NoGreenNoBlue.jpg. Do these results
support a very dark light cyan? Thanks.

RE: [Digital BW] Re: MIS UT2 Carbon prints very non-linear

2006-01-16 by Paul Roark

I assume that is the cyan ramp you printed.  It indicates the LC is missing.
Are you sure your nozzle checks are OK?

One nozzle was plugged -- #4 counting from the left. I did a couple of
cleaning cycles and re-printed the step wedge, cyan only, and it looks
exactly the same as before. At this point I'm going to work with MIS
to get me some replacement cartridges, and then see what I have.
Thanks for all your help.

Get the 2400.  None of those listed below are "professional" printers but
the 2400 will save you a lot of heartache and hassle.  The first
professional printer one could recommend is the Epson 4800.  Price that and
tell if you think the 2400 is still expensive by comparison.

Re: [Digital BW] Printer ??

I think Steve Kale is right about the R2400, Yoelis, and that until 
you wear it out creating lots of customers, the 2400 will be better 
for you than the 4800. That's why I just got a 2400.


A week or ten days ago, I paid Amazon.com's U.S. store $765.69 for a 
2400. No shipping charges, and no sales tax charges because it wasn't 
shipped to an address in Washington state, which is where Amazon is.

If the Epson Store's Clearance Center

<http://www.epson.com/cgi-bin/Store/BuyEpson/ccHome.jsp?BV_UseBVCookie=yes&ref=hdl>

had begun to have re-furbished 2400's yet, I would have gotten one of 
those instead for much less. But I guess it's too soon for that.


You might, however, consider getting an Epson Stylus Photo R220

<http://www.epson.com/cgi-bin/Store/consumer/consDetail.jsp?BV_UseBVCookie=yes&oid=58654761>

for about $100 new (or less used or re-furb'ed), and wearing _it_ out 
making only relatively small prints until refurbished 2400's start to 
show up at Epson's Clearance Center. I think that might be easier as 
well as less expensive, especially if you started with black-only 
(BO) B&W prints, which is what I'm going to do with the R200 $60 
re-furb I got a few months ago.

Good luck with whatever you do.
