There is a free program pnmtotiffcmyk in the pbm pack of conversion programs. Save your gimp image as pnm first of course.

When I used it on a photo the colors were a bit duller.

I can not wait untill 2010 to wait gimp supporting CMYK, if GIMP want

to

beat PS, the first target is supporting CMYK.

I don't think that the main idea of GIMP is to beat any other application. And also you didn't really read the whole mail did you?

He said j-o-k-e.....

But it will take time to do this things even though you might think it is easy it is not. You have to give things like this time.

And next time read the whole mail and don't read between the lines. What I think he tries to say is that there is no actual date for anything right now.

From my previous reply:
--------------------
The two programs mentioned above by Roland are part of the netpbm package
available on sourceforge.net. netpbm replaces some older utilities found in the pbmplus package.
-------------------
The programs come with Man pages. and there is some online help.

You are correct: CMYK capability will break down a big barrier and they are correct: this is not a trivial task. Jokes or no jokes, it is important to keep this objective at the front of the development effort. Ultimately we hope to be able to load, manipulate, save and separate CMYK images. The problem with conversion programs is color balance. CMYK has a more limited gamut than other formats. So when you convert the colors shift. To correct this shift one has to work more or less blind in some other form, like RGB.

As a stopgap a color correction feature that distorts an RGB image so that it uses the limited gamut of a corresponding CMYK image might be useful. I don't know about the technical practicalities of this however.

My thanks of course to the developer community that makes this at least a future dream if not a present reality.

Ahhaha it's my mistake, i know it was a joke, but i forget to tell you guys, that i also didn't very serious when telling that gimp beat other applications (f.e PS). I like GIMP a lot, in fact right now iam making a manga (japanese comic) using gimp, since it's only use grayscale mode. I dont have to worry about gamut or CMYK color corection.

If i want to making color illustration, i switch into W$ and run PS. Since it's faster coloring in PS, for printing only. If making color illustration for screen some time usin GIMP (linux).

OK, my apologize, if some one affense what i was said. But, it would be great if GIMP support CMYK (hehehe :) ), but i can wait......and pray, coz i can't help. I am not a apps programer. hehehe ;)

GIMP = Great Image Manipulation n Perfect
