Rick and Morty - Rick Einstein mug

Mug printing: The porcelain mug is printed using the Sublimation method.

Dye sublimation printing has become a popular and versatile process. An image is printed on a transfer paper which is brought into contact with the porcelain mug and with the help of a heat press. Under heat and pressure, the solid pigment sublimates and diffuses over it, causing it to stabilize on its surface. So the image becomes part of the mug.
