When I export a newsletter from inDesign CS5 to .pdf, certain B&W graphics show as inverted in Preview. The same file displays properly in Acrobat 9 Pro. These graphics were downloaded from the web, then changed to B&W mode. The settings for export are High Quality Print, compatible with Acrobat 8/9 (PDF 1.7).
Is this a problem with Preview?
I'm using OSX 10.8.4.
