Trust me, been doing this dance for quite awhile. 1. PDF with 100% of the fonts imbedded. Be careful of truetype some image-setters/digital presses hate them. or 2. Do everything in Illustrator and change ALL of the fonts to outline. or 3. Get all your files as .PS files and just drop them into the imagesetter. Again ALL fonts imbedded. Going thru and converting the fonts is a mistake. Time consuming and not 100% reliable. Puts waaaay too much responsibilty on you. Creates files that hafta be reproof read and approved. Might as well just create them directly on the PC. Good luck, this has been an ongoing problem for years. Hate to say it but your best bet would just buy a mac. Hope this helps Jon
