The printer is a ten color Epson Surecolor 80600 so I am sure it has enough gamut. I run a custom 24 patch color check with Colorthink spreadsheet and I have matched these colors on printers with smaller gamuts like color copiers. The Magenta is 46L, 57a and -9b. The ink restrictions were done by measuring the Onyx target so you are correct, I should look there. Also, I will plot the problem colors in Chromix to see if they indeed do fall within the gamut of the resulting profile. The problem could well be in the ink restrictions!Thanks, I will report back.
