Ahh, love those Surecolors - and good to hear you're on the S70. ONYX offers the "AccuPhoto GSX" "Contone" mode that utilizes preset calibration parameters that leads to an easy, 1 step profiling process. This will be "good enough" for many, but since these preset parameters aren't optimal for most media, advanced users will want to go through the more advanced procedure using the "Stochastic" mode, determining optimal ink limits, linearization curves, and total ink limiting for each media prior to profiling. I was at Epson's office earlier this year and they were telling me about how they optimized the AccuPhoto GSX for their canvas. They were blown away that I could beat the AccuPhoto GSX mode with a custom setup in Stochastic mode. Profile as CMYK in AccuPhoto GSX, and profile in CMYKO in Stochastic mode. i1Profiler is great in this mode especially with a few tweaks. In order for ONYX to recognize i1Profiler's DCS targets, you’ll need to edit the ONYX Quick Set, click “Advanced”, go the PS/Postscript tab, enable separations and add the appropriate channels. Use “All ICC Profiles OFF” when printing the target in ONYX. Of course, the Achilles heal of ONYX is knowing how to find the sweet spots for Ink Restrictions and Ink Limiting prior to profiling. That's a topic for another day! Scott Martin www.on-sight.com On Nov 4, 2013, at 12:42 PM, Randy Zaucha <zbet66@yahoo.com> wrote:
Yes, Epson Surecolor with Epson Elegant canvas. We are trying Matte, Satin and and Aurora AC Gloss and semi-gloss. Randy

Also tell us what media you're using as well as the media's ability to hold ink can dictate our usage of the Orange (some media will see a better gamut if you restrict the O and load up on the others inks while other media will benefit from O). The media plays a huge role in how successful the process and end results are.

I'm profiling a CMYK, lm, lc and Orange printer with an Onyx Rip, plus I also have i1 Profiler.
Both the Rip and i1 Profiler support 5 color schemes. The Rip has profile making ability too.
Do I set the Rip as CMYK+O and supply a CMYKO profile with i1 profiler? Do I set the as CMYK+O and supply a standard CMYK profile from i1 profiler? Do I set the Rip to CMYK+O and use the Onyx profile generation for a CMYK profile? Do I set the Rip for CMYK and install a CMYKO profile?
I'd like to optimize the use of the Orange ink for gamut expansion of course. Any ideas on the best way to go?
If I create the CMYKO profile using i1 Profiler, then I should measure a solid Orange ink patch on my media (canvas) and enter that into i1 Profiler. Should I enter the Lab values of an Orange patch that has the highest saturation I can print or highest density?
Thanks, Randy Zaucha
