creating CMYK PDFs on Mac
If you use the Mac OS X feature of printing to a PDF, you are quite a long way towards selfpublishing and POD (print on demand)... only thing you might run into a hurdle is the fact that all these PDFs are in RGB color mode, and your POD provider will most likely demand you deliver print ready CMYK colors. So, how?
Turns out that the ability to converst any RGB PDF to CMYK is built into any Mac in the form of ColorSync and it's Quartz Filters. I won't describe the details here, but following this HowTo got me all set up (the concepts apply to any App, not just Pages):
