Thermal transfer printing processing is also called thermal sublimation. It uses heat transfer ink to print portraits, landscapes and other pictures on printing paper, and then heats it within a few minutes through the corresponding thermal transfer equipment. It is a special process to transfer the color of the image on the paper to materials such as porcelain cups, porcelain plates, clothes, and metals at a certain temperature. Thermal transfer processing machines can be divided according to the type of machine.
Divided into: Heat Transfer Machine, ironing machine, high-pressure heat transfer machine, shaking head heat transfer machine, cup baking machine, baking pan machine, and lid baking machine. Thermal transfer printing is a new method of printing patterns on products of various materials. It is especially suitable for the production of small quantities of personalized and customized products, as well as the printing of patterns containing full-color images or photos. The principle is to use a printer to print the digital pattern on special transfer paper with special transfer ink, and then use a special transfer machine to accurately transfer the pattern to the product surface under high temperature and high pressure to complete product printing.
Thermal transfer technology can also use a variety of different transfer materials to achieve different printing effects, including film transfer and sublimation transfer. The Heat Transfer Paper for glue film transfer contains glue, and then the glue pattern is printed on the surface of the product through high temperature and high pressure. Sublimation transfer is a new generation technology that uses special Sublimation Ink and Sublimation Transfer Paper. The patterns printed on the product will not produce glue. If transferred to clothing, the ink is directly sublimated into clothing fibers, with the same durability as cloth dyeing and bright colors, making it more suitable for colorful patterns.
Products that can be heat transferred. Not all products can be thermal transfer printed, which involves factors such as the heat resistance and flatness of the product. Due to the continuous advancement of technology, products developed using thermal transfer printing technology include: clothes, bags, hats, pillows, mugs, ceramic tiles, watches, mouse pads, coasters, calendars, medals, and hundreds of other products.
Textile transfer printing: Common textile transfer printing technologies include film transfer and sublimation transfer. Sublimation transfer printing technology is mainly only suitable for clothes with polyester fiber (polyester) on the surface, such as quick-drying shirts and physical comfort shirts. White clothes are fine (the position of the printing pattern is white, but other parts of the clothes can be other colors , such as colored sleeves). After colored clothes undergo digital sublimation, the ink and colored fibers will fuse, making the color of the pattern different from the original color, so it is not recommended.

Film transfer printing technology is mainly used for clothes with extremely high cotton content. Film transfer can use various colors, but dark clothes require the use of higher-priced "dark clothes special transfer paper", the glue is heavier and the quality is unstable. Dark-colored clothing will not be released for transfer at the moment and will be released after the technology matures. Transfer printing of ceramic products Ceramic products use sublimation transfer printing. At high temperatures of around 200 degrees Celsius, the ink is sublimated onto the product, resulting in bright colors and high pattern reliability. However, ordinary mugs cannot be directly transferred and require a specially treated coating (coating) to transfer the pattern.
