ABSTRACT:
A method and apparatus for thermal transfer of a picture pattern or a letter on a printing surface of a material formed of metal or ceramics exhibiting high heat dissipating properties. The thermal transfer apparatus, by which the thermal transfer method may be carried out, includes a holding unit for holding the material and having a heater for heating the material, a thermal transfer head for heating the thermal transfer film for transferring the printing layer onto the material, a cooling unit for cooling the thermal transfer film, a peeling unit for peeling the base film of the thermal transfer film, and a control unit for pressing the thermal transfer head against the thermal transfer film as the material is heated by the heater for transferring the printing layer onto the material. The control unit causes the thermal transfer film to be cooled by the cooling means after separation of the thermal transfer head from the thermal transfer film. The control unit also causes the peeling unit to peel the base film off from the material.
