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 >>> Can you test the following?
