Overprints in Illustrator not correct in PDF

[William_Everhart@adobeforums.com]

I am trying to get a pdf of a print job that has elements told to overprint in the attributes window. The pdf looks great in Acrobat pro 6 with overprint preview turned on but most of my customers have only Reader and the overprints don't show up in Reader only the element that is told to overprint. I hope that explains my situation. I have tried printing the job to a pdf printer to no avail though I did get a six page pdf that contained a black and white image of each color when printing separations. If I could get that into a single page pdf with color it would be perfect. I have tried saving the job as an Illustrator 8 eps hoping for some help during the flattening process but I guess that only applies to objects with transparency effects applied. This job is too complex to have to dig through and create the overprints with transparency effects not to mention the other 20+ jobs I have to produce pdfs on everyday. Any HELP?

Many people are after overprint preview but without purchasing Acrobat
full version.

Have you attempted to print from the PDF and choose 'Simulate
Overprinting' in the ADVANCED section of Acrobat 6 Professionals' print
menu? The transparency will also bve flattened to your choice within
this menu as well .... Though Adobe DO NOT recommend you make a PDF of a
PDF ... but this might help you with your search for a 'Reader' with
'Professional' reading capabilities.

Although 'overprinting' and 'transparency' are different things - you
will find that once flattening occurs, you will have to rely upon the
'overprinting' features even more ...
