Toast Titanium 5.1.3 should work fine, particularly in OSX. However, older Toast versions on OS9 gave us no trouble either. Make sure you are using either "MacOS/Windows Hybrid" in Titanium, or pure ISO 9660 in other older toast versions. On the Mac use the eight dot three PC (DOS) naming convention. It only helps because there are still a LOT of ancient Windows machines out there. Long file names are not handled well in much of the world, even today. Next, when migrating down the food chain to a PC, always keep things as simple as possible. Flatten all layers in Photoshop and send the thing as a TIF file, uncompressed. All PC's should be able to read them. Even more bulletproof, and way simpler in OSX, is to use press ready PDF as your export medium. Everybody can ready them too. Above all, DO NOT USE the MacOS CDR utility. We encountered non-Windows readable discs with it. NEVER with Toast. It also does a weird job at making things ISO 9660 as to long file name truncation. Even older Toast iterations allows "Joliet" file naming convention, meaning certain PC's will read the long file names, though you should not be using them when going Mac -> PC. We go down the food chain everyday, because while the magazines we submit to are about 99.5% Mac-only, our clients are PC users, way too often for what they do with computers, and tragically often AOL dialup users as well. So it goes. ANOTHER CAVEAT: Never send a Windows user a CMYK jpeg image. Chances are, they will have utterly no clue what to do with it. Always convert CMYK to RGB JPG for non-printing client proofing, with a color caveat statement as to shift from said conversion. Richard Brown
