受像紙の受像層に転写する。The printing principle of the thermal transfer method is that the ink layer provided on one side of the transfer sheet substrate and the receiving layer provided on one side of the receiving substrate are opposed, and the printing is performed using, for example, a thermal head of a printer. The color material in the ink layer of the transfer sheet is transferred to the image-receiving layer of the image-receiving paper by heating the transfer sheet from the base side (the side opposite to the side with the ink layer).

られるという大きな特長を有している。There are two types of thermal transfer printers: a sublimation type that uses a heat-sublimable dye as a coloring material, and a melt-type printer that uses a heat-melting binder containing a pigment as a coloring material. Among these, the sublimation type is inferior to the melting type in terms of light resistance and sensitivity, but it has the great advantage of being excellent in single-gradation resolution and producing commercial quality recorded images.
