[magick-users] CMYK PDF read as CMY (without K channel).

[Pierre-Yves Landuré]

Hi,

I believe that :

convert -colorspace CMYK -profile ISOcoated_v2_eci.icc    INVIT_210x100_Vide.pdf  test.jpg

do what you are talking about. Please tell me if i'm wrong.

I think that the profile was applied to the jpg (as far as i can tell 
with my low knowledge of Photoshop).

I think that the fact that there is or not a profile is not the source 
of my CMYK -> RGB-> CMYK conversion problem. I want CMYK-> CMYK exact 
match, but i can't achieve it.

Thank you for the tip anyway,

Pierre-Yves
