Printing and sublimation
Dye sublimation is the ideal method for printing on fabric because the graphics can be machine-washed or dry-cleaned and still maintain fresh and vibrant colors. The principle of dye sublimation is simple: a strip of paper is printed (offset) in reverse so that the printed message will appear the right way once it is copied onto the desired material.
The paper and the fabric are overlaid and pressed against a heated cylinder (around 210°C) for a few seconds. The effect of the heat forces the ink to adhere to the fabric, and then the only thing left to do is separate the paper and the fabric when removing from the machine.
