RGB color management

[KellyT]

Hi all,

I just joined the site today...

I'm working with RGB files on Epson 11880's. I create custom color profiles which have always worked fine. Lately I've noticed a color shift, it's slight but there. I'm wondering if anyone can recommend a RIP software that works with RGB or any way to relinearize the printers so that I can maintain color consistency?

Thank you!

My vote is for Oynx.

Onyx would be a fine choice as production RIP even though their density based linearisation is outdated in my opinion and surpassed by many Lab based iterative based re-calibrating RIP's (mostly to be found in the proofing enviroment to be fair). However if you don't need all the bells and whistles on a RIP such as tiling, nesting, step & repeat, pre-flight/colour correction etc. etc .etc then why not just re-build an RGB output ICC as your problem seems to relate to the natural drift of the device. Alternatively you could invest in a package like XRite Monaco Profiler amongst others which allow for a pre-linearisation of RGB or CMYK ICC's which then allows for updating later.

You need to be mindful that a RIP will simply deliver values that are then sent to a marking engine. CHange paper, change your ink cartridges - color shifts. Temperature, humidity - these create shifts too. The pros use color management and often print control strips to make adjustment to get the device back into calibration - there are some that create / adjust / change profiles and a few that update tables, but these all require some device that measures the control strip.

I use the X-Rite ColorMunki (i need OCCATIONAL color adjustments) - others who do this several times a day have strip readers.

Hope this is helpful
