Thermal transfer printing method and thermal transfer printing system

Abstract

The invention provides a thermal transfer printing method and a thermal transfer printing system. The thermal transfer printing method is used for printing foaming ink of a thermal transfer printing film on an object in a transferring mode, and the foaming ink is foamed to form salient points. The thermal transfer printing system comprises a supporting member and a temperature control device, wherein the supporting member supports the object, the object is jointed with the thermal transfer printing film, and the temperature control device heats the thermal transfer printing film to lead the foaming ink on the thermal transfer printing film to foam and attach on one surface of the object. The thermal transfer printing method and the thermal transfer printing system break through the bottleneck of the traditional plane foam printing, attach the foaming ink on the curved surfaces of various objects, increase the adhesive force between the foaming ink and the object surfaces, use a mature thermal transfer printing technology to largely and stably produce and manufacture and avoid the unstable phenomenon of the traditional salient point processing technology.

Description

technical field [0001] The invention relates to a thermal transfer printing method and a thermal transfer printing system. And particularly, the present invention relates to a thermal transfer method and a thermal transfer system using a thermal transfer film printed with foaming ink. Background technique [0002] With the diversification of the consumer market, consumers' demand for commodities is also increasing. At present, single-color plastic injection molding is mostly used for products. To increase the diversity of the appearance of injection parts, printing is a better way. However, traditional printing is mostly carried out on flat surfaces, and the printing effect is slightly worse for surfaces with ups and downs. Therefore, for non-flat surfaces, thermal transfer printing or in-mold decoration technology is often used to increase the appearance diversity of injection parts. In order to meet the needs of appearance or functional design, the surface of the inject...

Problems solved by technology

However, for the bumps formed by secondary processing and stamping, the nearby structures may be damaged or even destroyed, and the pass rate in mass production is not high; the method of forming bumps by one-time direct injection molding requires Prepare different molds for different bump configurations, thereby increasing manufacturing costs, and the injection parts with different bump configurations are not high in commonality with each other, which also increases inventory costs; pasting the printed bumps on the surface of the injection parts method, the bumps are often loose due to long-term use, and it is difficult to locate when pasted again, and the pass rate is reduced
