CMYK Colour format ?

[miket]

Hi All !

I'm in the process of getting some brochures printed and need to supply my graphics
to the printing company in CMYK colour format rather than the normal RGB colour format.

Can anyone on here tell me which Linux Applications are capable of saving graphics
in the CMYK format rather than RGB format ???

Thanks !

Mike.

I think Krita does.

Hi,

I'm trying to following the instructions on http://cue.yellowmagic.info/softwares/s ... index.html ("Separate and separate_import plug-in" README file). I'm stuck on this line under Linux installation:

Next, modify Makefile by an editor as necessary. Regularly, PREFIX,
INSTALLDIR etc. will be modified to fit your environment.

This is a bit general for a noob like myself. How do I modify Makefile?

Please advise.

Thanks,
Nima

The CMYK can-of-worms

The separate+ plugin for gimp is in the repo - it is part of the "gimp-plugin-registry" package.

Big *but* you might be better off using ImageMagick (from memory should already be installed). Then you need to get hold of your publisher and ask about .icc colour profiles

The relevent imagemagick page is
http://www.imagemagick.org/Usage/formats/#color_profile

You can get colour profiles to practice on from the repo, icc-profiles package and some more from
http://www.color.org/registry/index.xalter

As a test, pop one of your images into your home folder along with one of the (cmyk not rgb) colour profiles, open a terminal and use a command along the lines of
convert rgb_image.tiff -profile cmyk_profile.icc cmyk_image.tiff


best of luck

Thanks, I tried

Code: Select all

convert rgb_image.tiff -profile cmyk_profile.icc cmyk_image.tiff 

and it returned:

convert: unable to open image `rgb_image.tiff': No such file or directory @ blob.c/OpenBlob/2480.
convert: missing an image filename `cmyk_image.tiff' @ convert.c/ConvertImageCommand/2838.

convert: unable to open image `rgb_image.tiff': No such file or directory @ blob.c/OpenBlob/2480.
convert: missing an image filename `cmyk_image.tiff' @ convert.c/ConvertImageCommand/2838.

That was a general form of command, as in "along the lines of" - missing an image filename is the giveaway , Try copying a real graphics file - does not have to be a .tiff file, could be jpeg - to home, plus an icc profile and substitute the appropriate filenames. Now try again. See what you come up with, and we will sort from there.
