I've used Onyx a lot to make profiles and I agree that setting ink limits has much to do with it. Onyx is a powerful tool but can easily mislead us when we're setting ink limits and restrictions. Glossy canvas in particular has issues due to reflections. I find Onyx profiling to be more like alchemy than science. Recent versions have added some automated simplicity, but I still don't trust it first time around. Let us know how you make out.

I'm using an Isis spectro with Onyx Thrive. My goal is to get the maximum printer gamut on canvas.Ink restrictions were set by reading the Onyx target into the Onyx Thrive. Pre-linearization is done on the printer, the Epson 80600. Ink limits were set by visually inspecting the Onyx target.Delta E is determined by measuring a custom 24 patch target I made and comparing it to the reference values in Colorthink. I agree that I would not want to use an editor. I displayed the ICC profile in Color think and put the 24 patch target up. All the patch points fit into the gamut except the violet patch. The Magenta has the highest Delta E which is 7.35. I'm going to try and increase the ink limits and see if the Delta E's go down.
