Question

Ghostscript changes colospace to RGB when converting CMYK eps to jpeg.The problem is to keep colorspace untouched during conversion. Thanx in advance.

Answer 1

Assuming you want to convert any RGB that may be in the EPS to CMYK, use this command on Windows:

gswin32c.exe ^
   -o c:/path/to/output-cmyk.jpeg ^
   -sDEVICE=jpegcmyk ^
    input-rgb.eps 

and this on Linux/Unix/MacOSX:

gs \
   -o /path/to/output-cmyk.jpeg \
   -sDEVICE=jpegcmyk \
    input-rgb.eps

Note, by default Ghostscript uses a resolution of 72 dpi for the JPEG output. If you want to change that to, say, 300 dpi, then add -r300 to the commandline.
