You're overthinking this exercise. Perhaps to you, a graphics person, this data is important. To the average user who just needs the document, they don't care about this metadata if they expect it in read-only form. I haven't cared a bit about the font information in any contract or other form I've received as a pdf and no one has ever complained about a scanned pdf I've sent them. They just want what's in the document itself. It's a good, compact and portable format that most people know what to do with. Few people outside of graphics departments have encountered a tiff; even fewer know what to do with it. ************************************************************************* ** List info, subscription management, list rules, archives, privacy ** ** policy, calmness, a member map, and more at http://www.cguys.org/ ** *************************************************************************
