Whew, a great help Peter - thanks! I was beginning to think that maybe I'd 'backed the wrong horse' in choosing Scribus, and that I'd have to start again with a commercial DTP program, with several weeks work wasted! The pages look OK without bleed and crop marks, so maybe they'll be OK for the printer. I think what I'll do is copy a test pair of pages to a USB drive and take it to the printer for checking. You state: "The PDF contains bleed and trim boxes that the printers imposition software adheres to, and crop marks are added for the final spreads." I don't see these marks. Are they invisible to a viewer, then? Thanks again for the help. Jim
