I am working with Linux and it seems to be a littlebit difficult to test if a resulting PDF from Context is cmyk (I don't have Adobe). With the frontend "display" from Imagemagick I get the following information about the pdf: Type=PaplatteMatte Colorspace=RGB Debth=16/8-bit Hasn't the PDF to be Colorspace=CMYK? Here is what I did: \setupcolors[state=start] \definecolor[myc] [c=.30, m=.60, y=.60, k=0] \starttext {\color[myc] Only some words} \page \stoptext Ho can I say to ConText: This PDF has to be CMYK?

You did, the tool you specified isn't doing a good job verifying that. The folio is Gray Color, brightness 0, the colour text is c30 m60 y60 k0 as expected (as checked w/ Enfocus PitStop). Acrobat Reader has some preflight capabilities --- check that. See: http://beckerprint.com/resources/ which has: Preflighting your PDFs In many cases, issues within PDF files can be found through Acrobat and Acrobat Reader's Preflight tool. The Preflight tool analyzes your PDF and returns a report listing potential problem areas within the file, including images in non-CMYK color spaces, colors within the document that are not CMYK, low-resolution images, layers that don't knock out, and so on. Preflighting on a Mac: • Open your PDF in Acrobat or Acrobat Reader. • Go to Advanced → Preflight. • Choose your desired Profile preset. • Hit Preflight. • Adjust your source files accordingly. Preflighting on a Windows computer: • Open your PDF in Acrobat or Acrobat Reader. • Go to Document → Preflight. • Choose your desired Profile preset. • Hit Analyze. • Adjust your source files accordingly. Not sure if the Linux version of Acrobat Reader has such capabilities or no --- perhaps Ghostscript has some facility at this?
