During the dye-sublimation printing process, a digital printer prints a mirror image on special transfer paper using sublimation ink. Under consistent pressure (45 sec) and at a consistent temperature (210 ° C), this transfer paper is inserted into the thermo transfer printing press together with the fabric to be printed on. 

Through the heat and the pressure of the press, the sublimation ink transitions into its gaseous state and sublimates into the polyester. Through this process the dyes are directly diffused into the polyester fabric. No imprint can be felt, since the dyes are directly in the fabric. 

By sublimating the ink with the polyester fabric, the fabric becomes extremely wash-resistant. The colors can even withstand the boiling of the fabric in the washing machine (boiling can lead to a slight fading of colors).

Since the chemical reaction only occurs when sublimating polyester fabrics, this printing technique can only be performed using polyester fabrics or blended fabric materials (at least 35% polyester).
