Tasty! :-) they have fantastic RIPS built in.. part of what contributes to the hideously expensive price tags that go with them. I had the pleasure of playing with a $260,000 hardware RIP for a few weeks some time back* - terabytes of hard drives and 8 processors.. it could do magic tricks! As my first trial I had it rendering a 1800 x 2000 pixel image up to a 48" x 53 " monster print - no one could believe it came from something as small as a 4" print! it really was quite remarkable.. fine hairs were 'enlarged' to look very sharp and with a great degree of apparent detail. I *know* the resulting print was to all intents and purposes a fictitious rendering based on a given input image, but hey, it looked GOOD.. still I suspect if *I* had $160,000 I'd spend it on something else.. (*it was part of my brief foray into being the state sales distribution manager for Canon wide format printers :) k
