transparancy IS the root of all prepress evils

(notice proper reaction to left) You must be working on some majorly complex files man. What sort of press is it printing on? Are you doing imposed films or plates? You may be able to cut your trap amount way back as well as use a lighter percent in teh trap mix to make tehm less noticable? Can ya cheat and rasterise some of the artwork that is using transparancy in PhotoShop and place it back in to the AI file? If your strokes have teh same color as teh fill I have found Rampage tends to treat it as a seperate object from the fill and you'll get a thin line between them when it traps. If that's the case outline the art then combine it into one object. or edit the trap and make the fill spread.
