This post has disturbed me because one shouldn't have to jump through so many hoops to perform a simple task. I tested this problem on my Mac with Illustrator 10.x, Quark 6.01 and Acrobat 6.01. First, in Illustrator, I made two squares, filled them with black, used the attributes palette to apply overprint to the black, moved one of the squares so it overlapped the other, selected both squares, and used the Make Compound command which created a white hole where the squares overlapped. I saved the drawing as an eps file. Second, in Quark, I made an object container and filled it with cyan. I made a second container on top of the first one. I placed the EPS file in that container, and changed the fill from white to none. I saved the file. Third, I printed the file using the Acrobat Create PDF printer. I checked the EPS overprint box. I did not export the PDF. Fourth, I printed a separated version of the PDF to my HP LaserJet 4200. The PDF separated properly. Try this simple test. Rich P.S. By the way, how are you testing your overprint to conclude that it isn't working properly. If you want to privately send me a simple Quark file, the Illustrator file, and your PDF, I will be happy to look at it for you. -----Original Message----- From: On Behalf Of Richard Eystad Sent: Thursday, April 29, 2004 7:56 AM To: [EMAIL PROTECTED] Subject: Re: [PDF] Retain Black Overprint I also apologize for picking this up in the middle, but a couple of things come to mind. Have you communicated to the prepress people at the newspapers your desire to overprint black. The reason I say that is we operate in a Creo/Scitex Brisque composite color prepress workflow in which black overprint and "honoring" postscript overprints in general are not automatic. In the Creo/Scitex Brisque prepress workflow, there are two rip settings affecting overprints. First, there is a black overprint setting that can be turned on (or left off). Doing so causes all 100% black lineart (vector art) to overprint regardless of what is called for in the file. We turn this setting on over 50% of the time (we look at the page elements and make a decision). Second, we have a postscipt overprint setting that can be turned on or off. Turning it on, causes the overprints set in the file to be honored. Turning it off, all overprint settings are ignored. In a Creo/Scitex Brisque composite color prepress workflow this setting is seldom turned on. The reason is trapping. If we honor PS overprints, all Quark/InDesign/Pagemaker, etc. traps (which are simply overprints) will be reflected in the ripped file. Once again, in a Creo/Scitex Brisque composite color prepress workflow world that is bad, because Creo/Scitex has an excellent trapping program that does a much better job. The reason I bore you with all this, is your problem might be with the rip workflow your vendor is using and not in your settings. If you print your file to a .ps file with separations turned on and then distill it, you should see each separation on a different PDF page and be able to see whether the overprints are being recognized. Once again, this is no guarantee a composite PDF will work. That is enough, back to work.
