Question for Paul R. Regarding his Custom ACV Files

Question for Paul R. Regarding his Custom ACV Files

2010-02-10 by robtmckay@aol.com

I've recently created my first custom ICC profile using Paul Roark's  
detailed instructions and Roy Harrington's Create ICC program. I am using an  
Epson 1400 loaded with the Eboni 6 inkset, and the profile I created is for  
printing on Premier Art b/w paper.
 
Before making the ICC, I downloaded Paul's ZIP file of Eboni 6 profiles.  
When I created my custom profile, I used his ACV file earmarked for Premier 
Art  B/W and the 1400. Then I printed out my own 21 step test strip and took 
readings  using my Color Vision Print Fix Pro Spectro. The ICC I made seems 
to be working  fine.
 
So here is my question:
 
I would like to make custom profiles for other papers such as Moab Entrada  
and Hahnemuhle Photo Rag. Will I be able to make good custom profiles if I  
use Paul's Premier Art b/w ACV curve file for these as well, or does  one 
need a custom made ACV file for each new paper one makes a profile  for?
 
Right now I am limiting myself to exclusive use of my 1400 and the EB6  
inkset.
 
Thanks in advance.
 
Rob

In general I've found that the same PS curves are close enough to be linearized with all matte papers.  So, you generally just have to print a 21-step with the curve on a new paper, read the test strip, and drop it and the curve (on the special rgb file) into Create ICC.

Note that here I'm talking about the monotone inksets.  The complex curves to control colors on, for example, UT7, often do not create even color tones on different paper coatings.

Thanks Paul, that is exactly what I wanted to know.

Ok, today I made profiles using Create ICC-RGB for the other papers I  am 
interested in and everything seemed to go fine.
 
But now I have a new, weird problem.
 
Suddenly I am unable to make prints using the new QTR profiles I made  
today, as well as those I made earlier and have printed successfully  with in 
the past. The 1400 printer seems to be working fine, I get a perfect  nozzle 
check and prints I make using any non QTR profile comes out fine. But the  
prints I make using the custom QTR profiles come looking almost like a couple 
of  the nozzles are not putting any ink down at all, almost a solarized 
look. When I  print out a grayscale, there is no smooth transition from black to 
white, the  print looks like a zebra's back in varying shades of gray.
 
I am assuming this is most likely due to some incorrect setting I have  
made in Photoshop in the print dialogue? I have checked over and over and  as 
far as I can see, I've got all the same settings for printing that I did  
before I started having this problem earlier today.
 
Any ideas what might be wrong? The profiles I made using QTR for Premier  
Art b/w and Moab Entrada worked fine up until I started having this problem  
today and now they are generating these messed up prints as well.

It sounds like a setting issue or software issue.  When I apply a curve to a file that I forgot to convert to RGB from GS it looks like that.  Try rebooting and recheck the settings.  Also, a calibration curve might show if there is a printer problem than is escaping detection in a nozzle check.

I've been doing some detective work and have narrowed the problem to the  
ICC profiles I made yesterday. What I said earlier is NOT correct, after 
another  test print I find the profile I made earlier for the Premier Art B/w 
still works  fine. 
 
One thing I recall that was different about making the "flawed" profiles  
yesterday:
 
When I initially opened the "rgb-raw-16.psd" file in Photoshop to place the 
 ACV curve on it, the little image was already yellow colored, NOT gray / 
black  like it was when I first opened it when making the PA BW profile. 
After I  placed the ACV curve on it, it turned yellow. But when I opened it to 
make the  profiles yesterday, it was already yellow when I first opened it 
and after  placing the ACV curve on it I saw no change.
 
Other than that, I cannot think of anything that was different in the  
process of making the profiles.
 
Could this be my problem? If so, what do I have to do to the  
<rgb-raw-16.psd> file to get it back to it's original configuration?
 
Thanks,
 
Rob

It sounds like you mistakenly saved the file after applying a curve, over-writing the original gs file.

If you need the GS one just send me your e-mail off list.
