Heat transfer ribbon refers to a printing method that transfers the pictures and texts on the intermediate carrier film to the substrate by corresponding pressure. According to the different pressure, heat transfer ribbon technology can be divided into water transfer, heat transfer, air transfer, screen transfer, low temperature transfer and so on. Among them, thermal transfer printing is to use thermal transfer ink (i.e. thermal sublimation ink) to print any image such as portrait and landscape on color inkjet paper (or special inkjet printing paper for thermal sublimation), or ordinary ink to print on adhesive film thermal transfer paper, and then heat it to a certain temperature within a few minutes through thermal transfer heating equipment to transfer the vivid color of the pattern on the paper to porcelain, glass, metal It is a special printing process for plastic, cotton, textile and other materials.
　　It can be seen that using thermal transfer technology, even for patterns of multiple colors, since thermal transfer is only a process, customers can shorten the work of printing patterns and reduce the loss of materials (finished products) caused by printing errors. In other words, using the thermal transfer ribbon film printing, the multi-color pattern can be mapped at one time without chromatic registration, and the realistic pattern can be printed even with some simple equipment. In this way, its applicability and transfer operation can be greatly improved.
