Hello Folks.
I use Gimp 2.8 on Debian 7 x_64 and when I want to open a PSD file Gimp tell me "failed: Error loading PSD file: Unsupported color mode: CMYK". I installed "Separate+" plug-in and a sub-menu added in image menu with the name "separate" and according to the below link I can't see the same Page
http://cue.yellowmagic.info/software...lus/index.html

my Gimp not have any "Adobe RGB" in source color space. How can I solve it?

Cheers.

Sounds like the installation instructions for separate+ weren't followed correctly, or you didn't download one of the requirements. Did you get the required Adobe ICC profile, from the Adobe site? Since you had to compile and install this from source, the README and the README_ICC_COLORSPACE contain the link to that requirement.

You can also use ImageMagick to convert a CMYK PSD file, to an RGB PNG file. Trying to convert PSD file to other image formats like .xcf, .tiff, etc. will create errors in the color profile, and maybe corrupt the output image totally.

a word of advice
using psd in gimp

--- forget about using it ---
the newer propitiatory formats will NEED ( for a small 200 meg psd image)
OVER 12 gig of ram and over 12 gig of swap space and EVERY CPU to open
and if you are LUCKY it will NOT crash your workstation

then if you are REALLY lucky and the workstation is still running
it will NOT open and display correctly

PhotoShop .psd is for INTERNAL USE IN PHOTOSHOP




WHAT version Adobe Photoshop propitiatory internal format of "psd" is this

Adobe uses the psd format for INTERNAL ONLY use
just like Gimp uses .xcf format for internal use

the current gimp will not be able to open a OLD xcf format( nor a xcf from cinepaint)
and the same goes for adobe photoshop

they are somewhat VERSION specific

also gimp needs a plugin for working with cmyk color format

if you really MUST convert a rgb to cmyk

i would use Imagemagick

or the better the tool in G'mic one of the hundreds of tools -- "rgb2cmyk"
supports 8 bit,16 bit and 32 bit image formats
