I've spent the afternoon searching theinternet but to no avail.
I'm trying to see if it's possible to script a process to take a color CMYK postscript file and convert it into color seperated files. From all the infromation I can find this is always done in Quark or Latex etc. but is it possible to get the seperations out of a color postscript file?
If I can't do that then I'll settle for this method, taking a seperated postscript file (from quark) and combine it into a composite. I saw that this should be possible in version 8 of GhostScript, it's not available yet is it?
Have a look at Aurora at http://www.cs.adfa.edu.au/~gfreeman/#Aurora
It allows you to separate files but is limited to Level 1 code. This probably won't worry you with Quark because I think its code is all Level 1 anyway
