I'm putting together a little event programme and some ads have been supplied as PDF with >300% ink coverage in some areas. The high ink areas were highlighted with InDesign's separation preview. I can fix this in Photoshop, but I want to reduce the amount of tinkering with the original files - is there a way to reduce high ink coverage areas in Acrobat? Running CS5.5 on OSX10.6. Cheers!
