Heat transfer printing method and device

Abstract

The invention discloses a heat transfer printing method and device. The heat transfer printing method comprises the following steps of: 1. designing negative images with required patterns; 2. printing the negative images with the patterns on a transfer printing roller by heat transfer printing ink; 3. transferring a pattern bearing area of the transfer printing roller to the surfaces of to-be-received-patters of a printed material so as to enable the pattern bearing area of the transfer printing roller and the surface of to-be-received-patters of the printed material to be in contact; and 4. removing residual ink in the pattern bearing area after the pattern bearing area and the surface of the to-be-received-patters of the printed material are out of contact. The method can be used for printing the patterns directly, and the time is saved and the material cost is lowered. The heat transfer printing device comprises an ink sprayer, the transfer printing roller, a heating mechanism and a cleaner. The transfer printing roller has the functions of receiving the patterns and transferring the patterns on the printed material. The device can simplify the heat transfer printing flow, can lower the printing cost, and can provide the useful help for products with individual decorations.

Description

technical field [0001] The invention relates to printing operation technology, in particular, to a thermal transfer printing method and a thermal transfer printing device suitable for the thermal transfer printing method. Background technique [0002] Transfer printing is a printing method that transfers the pattern on an intermediate medium sheet such as a carrier film to the substrate, that is, the final product, using corresponding pressure and temperature. According to the difference of transfer pressure and thermal conductive material, transfer printing can be divided into water transfer printing, thermal transfer printing, air transfer printing, screen transfer printing, low temperature transfer printing and so on. Among them, thermal transfer printing is to print any pattern such as portraits and landscapes with thermal transfer ink, that is, thermal sublimation ink, on a carrier film such as color inkjet paper or special inkjet printing paper for thermal sublimation,...
