Here is something that i believe is odd! Im working on an Illustrator file on CS6. Then i save it as PDF (press quality). Then i open the pdf file on Illu CS5. I get a msg that its generated by newer version etc. And finally, although its worked in CMYK color mode (in CS6), when opened in Illu CS5 its converted auto, in RGB color mode. Is that right? Shouldn't it keep the CMYK profile?
