Certified PDF SlideShare for ROC Friese Poort (Dutch)

I was asked to do a presentation for one of our clients, the ROC Friese Poort (a Graphic Design education) some time ago. The topic they’d like me to talk about was “what are Certified PDF files and how do you create them. I stumbled up on the Keynote files a few weeks ago and decided to put them up on SlideShare. I talk about the basics, the costs of ads in newspapers and what the main advantage of Certified PDF is.
