Frustrating experience #2 for this past week:
Tried implementing an ICC profile/ColorSync workflow for an Iris Realist
5015 and an Iris4Print both running IQ/Pro 5.0 RIP software. The procedure
goes something like:
1) Print profiling target using one of the "Iris Linear" Color Setups.
2) Measure and build profile.
3) Plug your "Iris" (destination) profile and "Target" (source/simulation)
profile into their ICC Setup preferences, select a rendering intent (AbsCol
in this case) and setting the default Color Setup the same as what you used
to print your target.
4) Print your proof.
5) Perfect proof print. NOT!
The results were far off from my Fuji ColorArt proof I was using as a
reference (yes, I made a profile from this same proof and used this as my
"target" simulation). The proof had a too-strong paper white tint and the
shadows were very flat although the amount of visible shadow detail was
about right. It almost looked like a CMY-only separation but examining with
a loupe you could see that there was indeed black ink being laid down.
Here's the strange thing:
I set up the same conversion in Photoshop 7 using AbsCol and the AppleCMM
and printed this with profiles disabled on the Iris but using the same Color
Setup as I used for my profiling target. Guess what? The Photoshop converted
image looked nearly perfect as compared to the one printed through the
IQ/Pro profile conversion. So have I "uncovered" some sort of bug with the
Iris ICC profile setup?
For the record, we did try upgrading the version of ColorSync on the Mac
from 3.0 to 3.0.3 and tried forcing the CMM (tried Apple and Heidelberg)
that was used instead of "Automatic". Nothing helped. A call to the
Creo/Scitex help desk confirmed that we were doing everything correctly.
Mac RIP was an older beige G3, OS 9.04, ColorSync 3.0.3.
Cheers,
Terry
