So I feel like I have asked this before but I couldn't find it on the previous posts. I am printing a booklet for a customer who is using indesign cs6. She then exports as a pdf for printing. I have attempted to print it now using just my rip software( Fiery ) and through acrobat. Each time there are curtain elements that have transparent boxes around them. I tried flattening it and messing with the out out color in Acrobat X pro. Problem changes but still presists. It only shows up when printed though so I can show any examples. Does any one have a good method for dealing with this problem. Keep in mind this a large book.
