Hi, First-time poster hear. Haven't run into this problem and could use some help. I have a Ricoh GX5050N and am trying to sublimate on white vapor t-shirt. The Ricoh prints are beautiful but when I try to sublimate the paper leaves a yellow tone where it touches the garment. tried even just the paper with no ink and it still leaves a yellow tint. I have tried reducing heat, reducing time, even spraying peroxide/water mix but no luck in not having that yellow tint. I have tried new paper and am waiting for the TextPrintR in the mail (which Conde recommended). Does tnis sound familiar to anyone. We started with a vaseline of 180-190 degrees at 40psi for 40 seconds, keep going low enough for sublimation ink not to take but still there is a yellow tint. Thanks in advance y'all!
