Rick, in my tests on OSX, Raw CMYK is broken. At some point the data
goes back to RGB, with a very detrimental 100% GCR. There was some
dialogue between some of us and the developers verifying the problem
months ago. To my knowledge the issue has never been rectified. The
behavior of the driver is better under normal RGB use than the RGB it
converts to when using Raw CMYK. I'm still hoping it will be addressed,
postscript and straight CMYK throughput would be great, particularly
given the purchase price

Subject: Gimp-Print Output Problem
Using Gimp-Print 4.26. and OS 10.2.6, I printed ECI2000 and TC 9.18 targets on an Epson 870. The pages were output out of QuarkXPress 6 with color management disabled (turned off in preferences).
The settings were:
Photo Paper
1440 x 720 (highest quality)
Photograph
Eventone Dither Algorithm
Six Color Photo
Raw CMYK for the ECI2000 and Color for the TC 9.18. Output was seasoned for several days.
I'm concerned because the target printouts are obviously skewed, and I can generate excellent profiles using the Epson driver. There are numerous light patches where there is no visible color. Target charts printed from the Epson driver (with no color management) are considerably darker.
I haven't yet reprinted the targets out of Photoshop (which I trust -- I'm still experimenting with Quark 6' s output), but my intention is to optimize them for use (particularly the CMYK) when printing from Quark.
Any clues before going off into a paper-wasting episode? Assuming that I can get a usable printout, what is the preferred dither algorithm -- adaptive hybrid, Eventone, or ???
