David, I'm afraid it a good bit more complicated. In ONYX you need to set the per channel ink limits, linearize, determine the total ink limiting all before making the profile. It kinda takes a PHD to get it all perfectly optimized. Simply going in and relinearizing and/or making a new profile likely isn't seeing the bigger picture. It might get them back to where they were earlier but chances are a fresh calibration from scratch could enable better quality than they've seen before. If it's the GS6000 we're talking about , the methodology we use to optimize color has evolved over the years and the newer approach yields incredible results. Which printer are you dealing with?

Good point Terry, thank you for reminding me. Larger patches? I don't follow, an increase in the patch count, or do you mean a physically larger patch size?
Scott, yes I am using Onyx which I used to use much more often, someone else prints from this printer and I get thrown in once in awhile to build a profile. Always a bit rusty on returning and need to refresh on the correct workflow. I see Ink Limiting was set in Onyx but the Lin file was not built there the last time.
So, lovely MediaManager, fine I will build the Linearization there and then print ICC targets generated from i1Profiler.
So, in the future when I update the linearization in Onyx how do I then update the ICC profile made from i1Profiler? Can I run new Onyx Linearization with the old profile? Seems an invalid approach, or do I need to print new ICC patches and make a new profile?
Thank you, David

David, I don't believe i1P's linearization step is what you would call a "linearization" in the traditional sense (tone curves of some sort)....I believe it's like MonacoPROFILER's linearization function where all it does is look at the tone/colorimetric distribution of the device and then produces an optimized patch set with device values meant to better model the device.....it does NOT modify device behavior like a traditional linearization/calibration curve.....for that you'd need a RIP.
As far as averaging more readings, if you're using an iSis or i1Pro, just build your chart with larger patches....as it scans, it should grab more readings per patch and average them.

I''ve been doing a lot of Epson GS6000 and Surecolor calibration the past 6 months and a working on an article about it. If you don't mind me asking, why are you linearizing in i1Profiler? Are you calibrating the printer in ONYX? If so, I know how ONYX can be a little funky especially in the black measurements in the linearization phase. I find that I get better readings wish I read patch-by-patch on the linearization step in ONYX with the i1Pro2 device. No so with the iSis or DTP70. With these spot measurements I'm getting a great linearization in the RIP and don't see a need to linearize in i1Profiler. I do like i1pP's profiles over NYX profiles...
As for i1Profiler, you can save as many measurement data sets as you like and drag and drop them on to the Measurement Icon to average them.
But again, I think it's important to get to the route of your problem. Linearization is best done in the RIP, not in i1Profiler, so if you're not getting a good lin in the RIP let's address that.
