Creating spot color PDFs with InDesign CS2

[cloudshift]

First off, this is my first post. Lots of great, helpful information here... So, thanks in advance, hopefully you can help me with my issue.

A little background about me. I'm the one and only prepress guy at a small print shop in FL. We do stuff for the music industry; CD packaging, record covers, posters, CD replication, DVD plackaging/replication etc. etc. We have a plate setter and an image setter... I mostly go direct to plate now, but we farm out some stuff and that's when I need to create PDFs.

I'm trying to create spot color PDFs from InDesign CS2, and I'm having some problems. Here's the setup:

I'm placing a DCS 2.0 spot color image, with 3 spots. I want to export a press optimized PDF to upload to a printer we use for larger runs, or other spot color type stuff. I could always just export from InDesign CS and not have a problem, but now in CS2, the PDFs don't look right at all, and the plates look nothing like they should... The same files export from CS fine, it's CS2 that's giving me hard times. I'm hoping to phase out CS, so I'd like to figure this out. Any information about creating spot color PDFs from InDesign would be appreciated... I must be doing something wrong.

This stuff will be run on an offset press on Neenah Paper - Environment - Sedona Red (in case you would like to know ;-)

Thanks much!
