I've been working on building a profile of a proofer at one of the
prepress shops our clients deal with and am running into difficulty
making cross rendered prints that match their proof. (We are an ad
agency working on entertainment advertising.)
Here's what I've done: Sent them a test image (one half of the page is
the PhotoDisc image and the other is the i1CMYK 1.1 target) which they
printed. Then I made a profile of their proofer, (with an EyeOne and
i1Match 3.0), and assigned this profile to the test image in PS. I saw
a good match on screen to their proof, but when I tried to make a
cross-rendered print on one of our in-house printers there was not a
good match.
In general the proof supplied by the vendor had a warm/yellow cast in
particular to the gray scale as well as to the print overall. The
cross-rendered prints I made all looked too blue, but when I tried
using Absolute Colorimetric to get it to match the paper white of the
proof the whites were way too yellow/dull looking.
I've done this successfully with other vendors and get a good screen to
print match using the profiles I've made for the in-house printers in
general. So I have confidence in the in-house part of the equation.
And the formula I followed for cross rendering is pretty simple - take
the test image, assign the new profile (good match on screen), then in
PS CS2's Print with Preview choose the profile for the in-house printer
and print to that device. I've tried both Relative Colorimetric and
Absolute Colorimetric intents. The Relative Colorimetric conversions
look too blue and the Absolute ones too dull and yellow. I've also
tried CS2's proofing options with the same results.
Any suggestions?
