I process ads for a magazine. We received an ad supplied as a PDF which had been constructed in FreeHand MX on a Mac and exported to PDF. Using Acrobat 9 Pro for the first time I used “Analyze and fix” (previously Acrobat 8 flagged up errors in preflighting without correcting them). The effect of “Analyze and fix” was to wreck the tracking and justification of the Helvetica Neue body copy (see attachment - before and after examples of an affected area). The font shows as properly embedded. This seems to be taking “fixing” a stage too far. What is happening?
