Can anyone share their settings for ek rip. I am getting good colors and using Andy's icons profile the white lays down nice, but when I press (cold peel) the white areas are dark and color vibrancy goes. I have tried adjusting the white output but then it just puts too much down and runs. My ink is fine well shaken all four white channels printing fine...just can't seem to get it. I press at 325 for 10 seconds then peel paper to press again but even after first press the white and colors look bad. Also using dtfsuperstore.com hot peel roll paper and powder. Thanks
