Hello all, My local printers only accepts PDFs (which is fine), and has recommended I flatten my 40 page PDF book design I exported from Adobe Indesign. Can this be done in Adobe Indesign before / during exporting? In a similar way I would in Adobe Photoshop for example? They suggested I use Adobe Distiller, but I haven't had any luck with that. This suggestion came after they printed a copy of the book: The cover was given to them as a separate PDF file which was saved from Adobe Illustrator. Problem is, the cover was printed to the correct size, but the actual 40 page interior of the book came out about an inch shorter, both in width and height? It should be a simple A4 book, I have no idea how or why this has happened? They had a look at my files and they said I had set everything up perfectly fine, with bleed and crop marks etc. They couldn't see any problems with the files. From what they said it sounds like the issue is on their end, but I just want to make sure I have crossed all the t's and dotted all the i's on my end first, before going back to them. Could flattening it be the solution? Another 'explanation' I was given is that it could be an issue with going from Mac to PC. I use a Mac, they use PC's... Any thoughts?
