Dr. Freeley,
first, put rubber sheets on your bed.
second, create B&W ps files, do not convert. Colors that are
very different can convert to the same greyscale, and cause
confusion in the b&w output (and you might not even notice).
as for CMYK, in the past I have opened the PS in photoshop of
paintshop pro and just converted to CMTK Tiffs for publication,
although it did run into various problems.
Cheers,
bob

You can look at my ps_on and ps_off routines (idl.tamu.edu) or Liam
Gumley's similar routines. Add the keywords you need and you're set.
Beware, the PS device driver only supports 8-bit color for lines
and the like (24-bit is only for images).
