ColorBurst is really only useful for doing CMYK proofing. That's what it's designed for.
Hi Jeff.
Have to disagree here - yes, it's great for proofing, but not limited to that (not designed to be limited to that, either).
It can output excellent presentation prints, fine art prints, pretty pictures - whatever you want to call them. In my experience, the key difference is control - *if the user has a spectro (UV-cut, unfortunately) and is willing to devote some time, linearizing & building custom profiles provides really comprehensive control of the print process - and great output. I think you need to "roll your own" custom profiles though - just using the RIP with supplied "canned" profiles has the same limitation as using Epson's driver with only the supplied profiles.
Granted, it's not as simple as printing straight out of LR to the Epson driver. But then you don't get "bit" as often by OS updates messing with color management in the print stream, either...
Regards,
John
