Great job by http://www.envisionprinting.com/ in highlighting these technical prepress issues and how to tackle finding them to preflight Adobe Acrobat PDFs. OK, but did you notice that most of the items he was checking for, are best checked and corrected well before the PDF stage? The main issues were:
* Non embedded fonts (missing fonts in native file)
* RGB images instead of CMYK
* Low Resolution Images
These common issues and more would have to be fixed by the graphic designer, back within their native files. Yes, it is utterly important to preflight Adobe Acrobat PDF you have created, however, by first preflighting and then creating a PDF, you will be ahead of the game. Not only that, but tools like Markzware‘s FlightCheck will not only check Adobe InDesign, Illustrator, QuarkXPress, etc, but also the resulting PDF through one VERY easy to use drag-and-drop interface. Furthermore, you can also package fonts and images together for archiving or compressing and sending to someone else the full job; it will even preflight Adobe Acrobat, check a PDF and collect non-embedded fonts used but not placed within a PDF!
