QTR-Quadtone RIP

Hi, I'm setting up QTR for a new Epson 7880 running PK ink,
and I'd like to create a custom profile for a glossy
paper, since all the profiles that come installed are for
MK ink/matte papers.

But when I print inkseparation.psd through the QTR print
driver as directed (selecting Quadtone RIP Calibration mode)
the paper is simply ejected from the printer and no image
is printed.

The QTR driver seems to be correctly installed, because when 
I print a ordinary test image using a MK profile, the 
image prints just fine (though of course not great looking
output.)

I must be making an obvious mistake, but I can't figure
out what it is. Does this ring a bell with anyone? I'm 
on a Mac, running through Photoshop CS4.

Thanks,
David

Hi David,

I'm not positive but I think that this is a problem with CS4 doing extra color
management on the separation file.  This is an issue I am looking into.
If there's any chance of using CS3 that's the easiest thing to do.

Unfortunately, I don't have CS3 available, but thanks for looking into
this, I'll watch the list for updates and sit tight.

Roy, can he assign GenericRGB to it so it will go through tagged as such and avoid 
potential problems?

I believe this will work.  Assign Generic RGB to the inkseparation file.  Then
print with Photoshop Manages Color and Generic RGB as the print profile.

Thanks Tyler and Roy, I'll try this. When I assign the profile, I
notice a difference on screen, by the way. Expected?

When printing using Photoshop Manages Color, I assume black point
compensation = unchecked, but which rendering intent is correct?

I just read Roy's reply that CS4 may be the problem.  I'm printing  
with a 2200 with CS3 and am about to install (maybe tomorrow) CS4.   
Is that going to be a problem for me, assuming I can install it  
correctly?  If a problem, can I still print from CS3 since it will  
still be installed.  Now that I'm thinking about this, will Lightroom  
be a problem, I also have it and will install it after CS4?

Thanks, Bob Gaunt

a change in display appearance with an "assign" is not unusual. The only thing that is 
happeningfor now, is how to display the numgers in your file. No change to the file itself 
is occurring.
Letting Photoshop manage colors is a safety net, as we try to get to the bottom of these 
problems. Since you are selecting a profile that is the same as the file is already tagged, 
there is a "null" conversion, nothing is happening. So intent and BPC settings don't matter.

It's a mess right now.

Okay, super. That worked. I've got a calibration page
printed and I'm off and running.

Hi Bob,

I have both CS3 and CS4 on my Mac and its just fine.  I would definitely
recommend loading both if you have them.  At the moment I´d recommend
printing from CS3 but do try CS4 and LR.  The issue is that they may print
darker or lighter -- they still function.
