Hi, i've tried it, and it is true that the black channel is not set to 0. But, i've opened the original PDF and the JPG resulting from the conversion with Illustrator and Photoshop (non free, but can handle CMYK).
And i get this colors : for a vector drawed item in PDF: PDF C: 0, M: 0, Y: 0, K: 77 -> JPG C: 70 , M: 70, Y: 70 , K: 0 And for a Text: PDF c: 75, M: 5, J: 100, K: 0 -> JPG: C: 65 , M: 36, Y: 76, K: 0 using the convert command line you gave me or the one i've first posted make no difference in the result. For me, it look like a CMYK -> CMY conversion, but i'm no specialist. I use Image Magick v 6.3.7 from Ubuntu Hardy Heron. Have you an idea of what is the source of the problem ? Thank you :) Pierre-Yves Landuré [EMAIL PROTECTED] a écrit : >> convert -colorspace CMYK original_cmyk.pdf result_cmyk.jpg >> > > Try > > convert original_cmyk.pdf -colorspace CMYK result_cmyk.jpg > identify -verbose result_cmyk.jpg > > Does the black channel show a standard-deviation other than 0?
