I donno. Best ask your printing house what they prefer in this case.

Just an additional comment about prepress. A very good and gratis pdf 
book (only in german!) about prepress basics can be found here:

http://www.cleverprinting.de/ratgeber2009.html

Simply press

"Jetzt als kostenloses PDF herunterladen"

at the end of the page to get a copy. If you like it, buy it (as it's 
also very cheap for technical literature).

Best wishes,  Peter
