Hi, Would please give a try to the precompiled icc2ps.exe located here?
http://www.littlecms.com/icc2ps.exe I've done some fixing in the CSA generation logic, and found some bugs. Additionally, this also has black point compensation feature for CRD. If this works fine to you, I will commit the chages to main sources, and do a new release or a patch to 1.11. Thanks.

I'm playing with it for generation of CSAs and CRDs for a PS-RIP for a laser color copier/printer, which works fine, except from the reproduction of white when simulating another CMYK colorspace via << /UseCIEColor true >> setpagedevice and remapping DeviceCMYK via a generated CSA. All colors look fine, but white does not remain white (regardless of rendering intent and CRD and originating Profile for CSA), it is always a bit dirty. Printing RGB images using an RGB-Profile -> CSA works fine, white remains white. The same CMYK-workflow in Photoshop 7 works too, only the in-rip conversion with the CSA fails. I don't have the deep background in color conversion mathematics and its implementation in PostSctipt (not yet, but I'm still hopeful...) So my question: Can I modify the originating profile or the CSA (or the generating code) to get a clear white in the simulation ? Or is it a bug in lcms ? It looks like the problem mentioned in this posting: http://sourceforge.net/mailarchive/forum.php?thread_id=2922755&forum_id=1912 If it is and will remain a bug - is there another (free or non-free) library for creating CSAs on Windows or Linux ? Thank you a lot !
