Digital BW, The Print

Has anyone successfully made a Chocolate Brown profile for QTR and UC 
ink. I am presently using Mohab Natural. The Sepia profile does not 
have the rich brown look I'm after and , unfortunately I do not have
an 
Eye-one as yet to be able to do the profile myself.

Try mixing one of the 'warm-1' profiles (K and LK only) with a selenium 
profile, or a second 'warm-1' That should get you close.

I think you can get pretty close just modifying one of the existing 
profiles. In QTRgui you can do the following:

1. Click 'Curve creation'.

2. File > Open > c:\Program 
files\QuadToneRIP\Profiles\2200-uc\UCmk-MEntradaNatural-sepia.qidf

3. Raise the ink limits for LM and Y (they should be 29 and 10 in the 
existing profile). You can think of the ink limits for LC, LM and Y as 
CMY values just like you would mix in Photoshop. The higher you set one 
of them the stronger that ink will tone your print.

4. Save the profile with a new name like UCmk-MEntradaNatural-brown.qidf
in the same folder.

5. Click 'Create curve'.

The profile should now appear in the 'Curves' drop-down list when you print.

I made a test curve raising LM to 45 and Y to 25 here:

Increasing the density of the toner also increases the density of the 
whole curve of course, so ideally you would want to relinearize after 
doing this. You might find that smaller changes are acceptable without 
relinearizing though.

I'm using the MIS Archival 7600 inks in the easy refill MIS 2200 
cartridges.

I've been pretty busy the last couple of weeks and the printer has been 
unused. When I made a print yesterday the print came out bright pink. 
Several nozzle checks did not show any problems.

I took out the cartridges, shaked them a little bit, put them back in
and ran a couple of head cleanings and everything was fine again. I now
get prints that match what I see on the screen.

Anyone else experienced this?

It happened again...

I've been away from the printer for five days, did a print, and it had a 
strong magenta cast. I took out all the cartridges, gave them a good 
shake and put them back in. Problem solved.

Am I the only one experiencing this?

This is with color prints using the MIS Archival 7600 inkset. I haven't 
had the same problem with the UT7 inks, but I guess the effect would be 
much harder to notice in a BW only inkset anyway.

I never had that problem with the GP Archival inks in my 9500. Can't 
comment on the UC replacements except doesn't the bottle say that it 
will not come out of suspension short of XXX months?

Could it be some kind of air bubble problem, and when you pull the 
carts and put them back in it somehow temporarily "fixes" the 
problem? Did you do a nozzel check before removing the carts?

Actually, it showed up with the original UT B&W formulas, but I
re-formulated them at the end of 2004 to get rid of the magenta -- the
problem.  That pigment tends to settle.  I speculate that the supplier made
them larger to try and offset their relatively weak lightfastness.  But, as
the particle size increases, the surface area to mass (weight) decreases.
So, the particles will tend to settle faster, all else being equal.  The
original 7600 UC clone inkset magenta had a higher viscosity in an attempt
to offset this.  However, this could not be maintained when the magenta was
mixed with the other inks in the B&W inkset (the other relevant inks have
essentially the same viscosity base), and the higher viscosity was not
compatible with the 1280 and other dye-based desktop printers -- thus the GP
inkset.

On most desktop printers the problem was also alleviated by regular use of
the printer.  The head agitates the ink carts.  So, the B&W UT problem
showed up most on printers like my 7500 with the UT1 inkset after I had not
printed for a while.

If you're using the 7600 inkset in a 2100, I'm a bit surprised that it shows
up.  But, as you've found, agitation takes care of it.  It does make me
wonder if the inkset you have is the 7600 clone or the GP inkset.

Yes, I think I've had a settling problem happen with my 2200 after
installing a new (but about 8 months past its "Use Before" date)
light-cyan cartridge. The subsequent color prints had neutral areas
that were distinctly quite reddish. It occured to me that the outdated
condition of the LC cartridge might be to blame, so I replaced it with
a fresher (in-date) one. The next prints were much more neutral (but
not
quite). So I began to suspect the nearly empty cyan cartridge, which
was of a similar past-dated vintage (with a production date in late
2002). When I replaced it, the neutrals improved even more.

I concluded that the out-of-date cartridge(s) had settled, even though
when I installed them I gave it a quite few extra shakes (10 instead
of 5). I suspect the settling eventually becomes irreversible. That's
not uncommon with dispersed colloids--nothing is forever. However I
did not try simply removing the either of those cyan cartridges and
try shaking some more--that might have helped.

This was with Epson UC inks. It probably also explains why-- a few
weeks ago when I was doing B&W (QTR) printing with these UC inks--I
needed to use a 100% "cool" profile in order to print neutral tones.

The bottles say ESC-7600 so I'm pretty sure it's the right inkset. I've 
mailed MIS tech support about the issue. I'll just wait and see what 
they say.

I would hope the inks could be a little more stable than this. Five days 
away from the printer is not a very long time. Another problem I've 
noticed is that the inks mottle in the magenta and blue tones on glossy 
papers using MIS photo black. On matte papers they look great.

I checked the date, and I ordered the inks august last year. I don't 
know if there's been any changes to the inkset since then?

Question about black point setting. I have an Image Print RIP. Yo can move  
black point from 
0-100. I assume 0 brings out the blackest. Please advise..and thanks.  -sm

The recent GP inks have worked great for me, no visible settling in the 
bottom of my ink bottles. So unless the older inks are at fault, it 
shouldn't be the problem. I was using the GP (really Image Specialists 
Ultra) in my 9500 with bottle feed system. Now I'm using the UltraPro 
inks, and same goes, no signs of settling after several days of no use.

The ultrachrome replacement inks are really Image Specialists Ultra II 
inks, the Eboni black is the only one I'm not sure of, but the UltraPro 
matte black seems to be slightly better, or at least the same.

After mailing back and forth with MIS about this issue they ended up saying
that the settling issue is normal and nothing can be done about it except
use the autoprint program to print something every day.

This is disappointing. Anyone know about other high quality color inks in
the same price range that doesn't have this problem?
