Hello all,

How can I make CMYK color seperations in cs2, can't find anything on
tthe subject.

You have a right to expect some guidance from either the printer, or the
shop that is doing the prepress. After using the Custom CMYK options in
Color Settings to specify the correct dot gain, total ink, and black
generation, or assigning an appropriate CMYK profile, convert your document
to CMYK mode.

The printer may be able to provide a dot gain and total ink limit numbers.
If no such numbers are available you can arrive at a good approximation
depending on the stock, whether glossy or newsprint, etc. Absent any
information about press conditions, the Euroscale or ISO CMYK profiles
provided with Photoshop are useful approximations. It is unusual for the
printer to be in a position to provide you with a profile for a particular
press.

If your work has line art you must use trap to prevent color fringing. Type
must be separated to the black plate only. Generally you will save the
image in TIFF format.

Probably the best book on this subject is Professional Photoshop by Dan
Margulis. It has guidelines for various printing conditions, and a wealth
of information and examples. The Pocket Pal from International Paper is an
inexpensive guide to terminology, printing processes, and basic procedures.
Consider posting any further questions to comp.publish.prepress, where there
are professionals familiar with printing.
