  • the sublimation printing is a relatively new printing process in which the ink is evaporated (sublimed) into the carrier and thus diffused into the carrier. After transferring to the material to be printed, the sublimation printing does not cause any inking since the ink completely evaporates into the material. Beforehand, a corresponding carrier is printed with the sublimation ink and then transferred by heat and under pressure to the material to be printed with a transfer press.
