Yea, separate it to print.
We work 99% of the time in Illustrator.
I had my guy drop it in PS to start with but I thought it was raster. Then when his DCS file wasn't working for him I sat down and saw it was an embedded smart object and thought... wait it's vector? And then he told me it was PDF... so I went back to vector and started working it that way.
Should I just stick with standard PS seps?
