If you are just doing basic monochrome text, no images, you can probably ignore 99% of this stuff. But any moderately complex document needs to be preflighted to make sure that it gets printed the way you intend. cf http://help.adobe.com/en_US/acrobat/using/WS58a04a822e3e50102bd615109794195ff-7b81.w.html http://help.adobe.com/en_US/acrobat/using/WS58a04a822e3e5010... http://tv.adobe.com/watch/learn-acrobat-9/preflighting-for-creative-pros/ http://tv.adobe.com/watch/learn-acrobat-9/preflighting-for-c... Generally when preflighting, I'm shooting for PDF/X or PDF/A compliance as well as, even without being strictly compliant, making sure that there are no document structure issues that are going act like a hangnail when the printer is trying to either digitally print the file or prepare it for offset printing. It's easy to think that a PDF is a PDF, but there are so many different things that can be stuffed into one and so many variations on how graphics and text containers format and interact that results can be surprising, particularly at 7pm on Friday with an expected Monday delivery. E.g. should that text with an opacity value be flattened? What if there is an image behind it? And a gradient? (actual recent example). I've had cases where the document "just won't print past page 40" (again, this past year). Why? No one knew. The technician handling the document was not good at troubleshooting. Acrobat preflight had passed it fine. There was an empty text frame on that page that the digital printer was choking on. I won't even touch on color issues here, but they can be equally thorny.
