Using postscript for ink management...

Greetings,
Suppose I have an illustrator, photoshop or indesign file with 3 colours in
it as follows:

A medium red:
C 0%
M 100%
Y 100%
K 010%

A dark red:
C 0%
M 100%
Y 100%
K 040%

And black:
K 100%

I want to have this file print with two inks on a press: Black and Pantone
Red 032C.

How do I control the Print options when I print to a (adobe) Postscript file
to get my output file to be rendered with the two inks (black and red 032c)?

Can I do this by Printing to a postscript file? Can I use the Output tab to
render my document to my predefined inks?
How else can I render my file to limited inks, e.g. spots instead of CMYK?

Thank you very much for your help!

It very much depends how your file was authored. You say "Illustrator,
Photoshop or InDesign" but the solutions differ somewhat in each, and
depend on details of the art.

One solution in Illustrator and InDesign is to use the existing custom
inks facility. Another solution valid in all three programs is to
assign a process plate (say M) to PMS Red 032 and assign say K to
Black, and colour elements accordingly. In fact it looks as if your
file would separate more or less correctly taking M and K from the
above breakdowns unchanged, as the two inks.
