Hello All, The CMYK RIP product from ColorBurst seems to be at the end of its life, at least the Mac version of XProof anyway. All the signs seem to indicate this: The company says it will not be updated to a 64-bit version, will never support new hardware like the i1Pro 2. They have removed the user-to-user support postings from their website, and have sent out emails offering existing users an incentive to crossgrade to their RGB RIP, Overdrive. I have been a satisfied user of XProof for years, both for proofing and for my own art, "presentation prints" if you will, and have installed & supported XProof at other companies as well. Maybe I will move to Overdrive, but I wanted to ask here on this list first. Especially if anyone has made the jump from XProof, I would love to hear about your experience. A few questions that come to mind: Is (RGB) Overdrive as capable for proofing (for offset repro) as (CMYK) XProof? I assume Overdrive does not provide linearization capabilities like XProof - if RGB profiling must include ink limits & linearization, does this limit the quality of output achievable? I assume Overdrive uses the same Postscript interpreter (Jaws?) as XProof - pretty good for RIPing PS output, but for raster output, does Overdrive offer any advantage over simply using the Epson RGB driver for my SP7880? I also found much better success soft proofing with my custom CMYK profiles for XProof than with custom RGB profiles - not exactly sure why, I speculated that it might be related to the behind-the-scenes "extra" conversion supplied by the Epson RGB driver (to the CcMmYKk inkset), as compared to the XProof "drive the printer as a CMYK device" approach -- sorry, that's a long preamble to asking how well Overdrive RGB profiles soft proof. Feel free to respond off-list if this is too narrow a topic. I just thought this group might have some folks who can speak to my questions. Thanks, John Lund JWL Images Emeryville, CA
