Did you know that black is the last color to sublimate during the heating process? Determine your optimal pressing technique by printing an RGB black image (0,0,0) and then transfer onto the desired substrate. If you get a great black, you are dialed in. If you don’t, adjust your press’s time and/or temperature until you get it right.
