Title:
HEAT TRANSFER SYSTEM AND HEAT TRANSFER METHOD
Document Type and Number:
WIPO Patent Application WO/2021/060549
Kind Code:
A1
Abstract:
[Problem] To enable the surface of an overcoat layer on an image receiving paper to be made smooth, and to simplify a manufacturing process. [Solution] A heat transfer system 10 comprises: an ink ribbon supply unit 11; a thermal head 20; a platen roller 15; and an ink ribbon winding unit 12. The thermal head 20 includes a heating resistor 22 and a line heater 23 provided from the upstream side toward the downstream side. The heating resistor 22 of the thermal head 20 transfers a colored layer 3 and an overcoat layer 4 of an ink ribbon 1 to an image receiving paper 5. The line heater 23 heats and smooths the overcoat layer 4. Either one of the thermal head 20 and the platen roller 15 can move in a conveyance direction of the ink ribbon 1.
