Pages produces PDFs that don't display consistently
So I have a pages document that has some photos with picture frame masks (I think some transparency masks). When I make a PDF from them they display fine on Preview, but the photos are messed up (masks either missing or the original photo and the mask are shown) when I open them in Illustrator CS5 for the Mac or on a PC. What gives? How do I create PDFs that display consistently?
Thanks!
