You might want to try putting 'gimp cmyk' into Google and have a read

Hi, I have just added to the mail list and here I bring some questions: What about Gimp support for CMYK color mode? Have you discuss about it? Will Gimp handle CMYK images? Can a graphic designer who works with CMYK images to send to printer work with Linux and Gimp?

Hi,

Gimp has some support for CYMK colour mode in the sense that you can decompose your RGB image into CYMK. With the help of the separate plugin ( http://www.blackfiveservices.co.uk/separate.shtml ), you can even save to tiff.

But if you need more advanced CYMK tools, you may have a look at either krita (the KDE image tool) or cinepaint.

Best regards,

Olivier

In terms of color management, Cinepaint and GIMP are more or less on a par now (at least, in the 2.3 series). Neither has native CMYK editing, to my knowledge.

Krita's been adding functionality very fast recently - they now have La*b*, CMYK and RGBA, and apparently layer groups are going in soon. I haven't used any later versions yet.

Cheers, Dave.

Well, I have not had a look at cinepaint for a while (I am not in the film industry, so it is not relevant for my use), so I am ready to believe you.

[off-topic class="enhancement request"] What would be nice for Krita/Gimp/ggl/gegl/whatever would be to also provide the L*u*v* space (CIELUV) because it is more relevant in TV industry than L*a*b* (see Hunt, "measuring colour", p66). [/off-topic]

And, just to be nitpicking, it is L*a*b* not La*b*. L is the luminance. the CIELAB space is based on the lightness L*. ;)

Dave.
