For print I always use an output format of pdf
X/1-a:2001 which doesn't allow transparencies. 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

It was created for my use years ago by one of
the experts on the icc_users mailing list.
