How to do RGB to CMYK conversion for PS output? [message #49318]

Hello there,

A colleague produced a colour X-Y plot for a paper and saved it to a regular old PS file.
The editor mailed back stating that the file contains RGB colours and could we please
create the file in CMYK colours.

How does one do this? Using
DEVICE,/CMYK
produced exactly the same PS file.

Doing,
TVLCT,r,g,b,/GET
CMYK_CONVERT,c,m,y,k,r,g,b,/TO_CMYK
produced the appropriate c, m, y, and k arrays, but how does one "load" the CMYK arrays to
be used? Doing
TVLCT,c,m,y
produced exactly what I thought would happen - no black.

Any ideas?

Thanks,

paulv
