PANTONE colors are expressed in PostScript as a pair, the Spot color,
and the Process color.  The CMYK array provides for things like
translation into RGB for the display or  for 4color ink-jet printers and
the spot color is the actual premixed iink.  If you know the name of the
spot color, the easiest way to get the CMYK values is to set a
rectangle, using the swatch library in Adobe Illustrator, and save it in
EPS.  The Custom colors appear among the first lines of the EPS file,
The example above plays a couple of games with the stack, but I don't do
that any more.  If I have 0 values in the process color I just write dup
0.0 mul exch
