Please, help me APU -- You can't, and this is the major shortcoming of Gimp. It is possible to convert to CMYK at the end of the process, but given the difference in gamut between the RGB and CMYK versions of the same image the quality of the result can be best described as uncertain. In an earlier post I discussed the program pnmtotiffcmyk which will indeed create a cmyk version of the file. However the colors do shift. This is especially problematic in photos of people involving flesh tones. The Gimp manual addresses this issue in chapter 13.

I believe Adobe owns the right to this process and has been very reluctant to release any rights to it. I think the Gimp programmers or others have tried and continue to work on ways around this limitation as John pointed out here. Although Gimp doesn't provide the simplest process of doing CMYK, it can do it in most respects. Like the old saying though, you kinda have to go around the elbow to get to the hand. :o) Hopefully a solution to the CMYK seperation problem will be forthcoming in a later version of Gimp, because that seems to be it's only weak point at the moment for most professional users.

Speak for yourself. For me, Gimp's major shortcomings are lack of proper colourspace management and inability to work on 16-bit (per R,G,B) images (sure you can read 16-bit TIFFs, but the extra data is thrown away). As a working photographer, these things give me the most pain. I'm sure there are other features (or lack thereof) which give other people pain apart from the lack of good CMYK support. Not to say that CMYK doesn't deserve attention, just to note that it's not the Gimp's only weak point. __ David Burren ___ Gimp-user mailing list [EMAIL PROTECTED] http://lists.xcf.berkeley.edu/mailman/listinfo/gimp-user

It seemed like CMYK was one that was complained about a lot, so I gathered it was one of the biggies everyone would like to have fixed. Gimp is always a work in progress and with the ability to program scripts and the work of the programmers it continues to grow and get better.

Re: [Gimp-user] Gimp and CMYK DTP
Let me add that the gimp is an extremely useful tool for a lot more than just artwork. I am using it for technical documents, aerial photos, and document archival applications... It has a few weak points in those areas too, but I'm working on some of 'em... :-) s/KAM - Original Message - From: Patrick [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Tuesday, October 29, 2002 7:12 PM Subject: Re: [Gimp-user] Gimp and CMYK DTP On Tuesday 29 October 2002 17:46, David Burren wrote: On Tue, 29 Oct 2002 15:13:55 CDT, Patrick [EMAIL PROTECTED] wrote: Hopefully a solution to the CMYK seperation problem will be forthcoming in a later version of Gimp, because that seems to be it's only weak point at the moment for most professional users.
