It's not you, your ICC profiles or the printer. It's the sublimation ink. It's always low contrast and dark from what you see on your monitor. No amount of colour management will change the capabilities of the ink. The only way to "correct" this issue of dark colours is to get a printer that can convert to sublimation ink with a minimum of 6 colours. The more, obviously the better.I have an Epson WF-7710 that I recently converted for sublimation printing but my colors are not vibrant and it just looks dull and faded.. Not really sure what I'm doing wrong but I did about 12 nozzle checks and 2 head cleanings after converting and the nozzle checks come out perfect every single time. It's just when I try to print images that the colors look really faded and inaccurate. Ex: an image of myself in front of a green screen background printed out with my face being too bright and the green screen fabric looking more blue than green.. Any ideas???
