Thermal transfer printing is a digital printing process in which material is applied to paper (or some other material) by melting a coating of ribbon so that it stays glued to the material on which the print is applied. It contrasts with direct thermal printing where no ribbon is present in the process. It was invented by SATO corporation around the late 1940s.
Thermal transfer printing produces crisp images onto labels. Heat is still used in this process except the heat does not come in contact with the label. Instead the hot print head causes the resin of a ribbon to form a high quality image on a label.
