Any transparencies should be converted to bitmaps via Gimp, imagemagick etc. Of course you should always use CMYK colors instead of RGB for printing. When excessive ink coverage is involved I use an icc profile SWOPcoated5_240.icc which limits the ink coverage to coverage to 240%. I will post it at http://wexfordpress.net/SWOPcoated5_240.icc It was created for my use years ago by one of the experts on the icc_users mailing list.
