What's the easiest way to force select pages of a PDF file from rich black objects to straight K? I know some RIP drivers provide this option, but my fiery does not so I either have to manually turn the pages and print one side color, one bw to the driver or find a way to easily modify them in the pdf itself so I can duplex or booklet print and not get clicked color for the "bw" sides because of the rich black objects that should be straight black.

Enfocus Pitstop Professional (Acrobat plugin) has this option.
