I have created a catalog page (CMYK) in InDesign CS4 and a title "Adventures" in yellow, font outlined with a dropshadow. Somehow the PDF looks fine on screen but when printed, it shows the "A" of adventures darker, sort of behind the shadow but the other letters are fine. That said, the A in question is right on the edge of a cloud on the photo.
I wonder what is causing this problem, any clue?
