Thanks for this excellent guide! I was quite successful with my Epson TW-3200 aka 8350, but am having troubles with green saturation.
I calibrated green to 75%, and was able to achieve exactly 133% green, 15% blue, 15% red as prescribed. I double-checked the x and y values, and they are also as per the spreadsheet, as are values at 25% saturation.
Now, when I run Measures/Saturations with Color HCFR, I get the attached result (updated, see below). DeltaEs are good or not too bad, but green is way out there, peaking at deltaE of 13 at 50% saturation.
Gamma is 2.2, color temp 6500k, RGB levels around 1 deltaE from 30% grey onward. Any tips on what's going on and how to fix green saturation, or is that just the way things are?
edit: I neglected to calibrate Y for each of the colors. After re-calibrating with them I get the attached results. Much better
Green is still the main offender at 25%, 50% and 100%, but improvement is significant. I even tried calibrating green only at 50%, but then the other points were even more off.
