Installed Linux and caldera on one machine. We are using GrandRip+ and print on Seiko is good (no banding at all!!!!), but (in my opinion) not better than onyx and photoprint.
there are some advanced options and some fine solutions. but on the first look i think i'll stick to the onyx because it is most powerfull RIP, and for scanvec amiable software (FlexiSign, PhotoPrint, ...) i think it's also powerfull (not as ONYX), but way easier to learn and handle. So if you can't (want) master onyx then i reccomend scanvec tools...
I will post again in few days when i look caldera bit more
I don't know which Onyx you are using but compared with the standard Onyx, Scanvec is just so much clearer and easier to use. So much more logical. And Caldera takes it all even a step further with being so powerful it's unimaginable. We've run both Onyx and Scanvec on the same computer, now with Caldera all the ripping and opening and all operations are just so much faster. And i know that even with big versions of Onyx the whole system is just less logical, less user friendly. All my employees want Caldera now. But sorry, they cannot run it on other machines.
Oh, and i've seen Colorburst last week. It's also less clear and less intuitive than Scanvec and Caldera.
nothing terrible about it. I guess I'm just more familiar with onyx and colorburst so finding things wasn't as easy. i also had trouble getting my DTP41 to work on the MAC properly so I wasn't able create profiles. I was able to manually linearize and create ink limits but not create ICCs.
Made in France.. the Interface is quite pretty.. prints well if you can find/build profiles. one of the most fustrating times of my life, Caldera CANNOT print dense enough for backlits! We made our own profile - got crap, had media supplier make profile - got crap, sent samples to France - got crap and excuses, switched to Onyx PosterShop and now print sellable backlits.

Yeah, we had same problem. Bought a USB to RS232 converter and it worked, but the ICC builder is WAY too pricey.
With Caldera there are no real problems so far. Sure, if i'd want to position multiple prints or do some cropping and stuff from within Caldera, i still can't figure out how to. But so far so good, works flawlessly. If only the ColorPainter was USB or TCP/IP... SCSI is a pain in the butt...
not going to happen unless you buy the hp. not overly fussed about scsi, cos i like the stability. cable length is a major pain but that's life and we have to work around it.
i've used caldera for our xerox colorgraphx x2 for several years. i really like arranging prints on a sheet the way i want them, better than onyx lining them up automatically. the linux pc rips really fast (it's a pentium 4 2.2ghz pc).
BUT... no one in our office really knows much about linux os, so WOE IS US when something goes wrong! good thing we have some unix knowledge.
we've had mysterious troubles when our color profiles went all out of whack. i gave up trying to get help from the company in france. but on the whole it is a good package and easy to use.
we wanted to connect our x2 to the onyx rip along with our seiko, but 6.5 apparently won't support the xerox. <sad face>
SERIOUS PLEA FOR EXPERT HELP... does anyone here really know a lot about using caldera? the printer used to work beautifully with the xerox 720 presentation profile, on that xpress 54 paper.
then the profile seemed to go haywire, and even though we made our own custom curves, it still prints way too dark.
hi we use caldera were we work and all the coulours have gone wrong if we print in black and white it comes out tinted red has any one had this problem and if so did any one sole it any help or advise about caldera would be most appreciated
