A printer I want to use only handles files which use CMYK colorspace/model.. I tried building my mkiv file using cmyk=yes, as shown below: \setupcolors[state=start, rgb=no, cmyk=yes, overprint=yes] Using ImageMagick's identify program to check the resulting file it show the following: Resolution: 72x72 Print size: 3.58333x2.16667 Units: Undefined Type: PaletteMatte Endianess: Undefined Colorspace: RGBde delegate for this image format `/home/user_a' @ error/constitut Depth: 16/8-bit. Channel depth: red: 8-bit green: 8-bit blue: 8-bit alpha: 1-bit GIMP also shows an RGB model for the resulting pdf file. Also is this mention of pixel resultion of 72x72 correct or useful? I tried to get a 300 dpi resolution for output. Any ideas and advice would be appreciated.
