Okay. 1. PDF/X plus does not mean "more stringent" - it is simply someone who builds a profile that checks to see if a PDF file meets the requirement of PDF/X and then checks for something else that may not be required by everyone. An example is Time Warner - simply accepting PDF/X files would allow low resolution images and the potential of a spot color in the PDF - in automated workflows, that might mean that you would run an entire set of plates that needs to be thrown out, or that spot colored object simply go missing. So, the Preflight profile rejects PDF files that have Spot colors, even though they be perfectly valid PDF/X files. There is no one 'right way' - and many people who have older systems (or poorly implemented PostScript interpreters, as you suggested) can't process PDF files that contain CID fonts in them. Worse, since Time Warner can't control where the files get made into plates at the 50 or so printers they use world wide, well, hey, they did their tests, and they came up with a procedure that works 100% of the time, despite some inexpensive prepress or print service provider that has old or bad RIPs. So, one can be academic and say "hey, CID font encoding works, and I can prove it" and I can walk you into a printer in Mubia, India or Bogata Columbia and say "you are Meshungina" - hey don�t be such a kvetch! LOL Anyway, have a great weekend everyone, and happy valentines day. ========================================= Cheers, Michael Jahn H: 310 540 6950 1104 Esplanade F: 310 540 8369 Suite 102 I: http://www.jahn.org/ Redondo Beach E: [EMAIL PROTECTED] California 90277 ========================================= To change your subscription: http://www.pdfzone.com/discussions/lists-pdf.html
