It has only been more than 10 years since thermal transfer was introduced from abroad. The printing method of this process is divided into two parts: transfer film printing and transfer processing. Transfer film printing adopts dot printing (resolution up to 300dpi), and the pattern is pre-printed on the surface of the film. The printed pattern is rich in layers, bright in color, ever-changing, with small color difference and good reproducibility, which can meet the requirements of the designer and is suitable for mass production; transfer processing uses a thermal transfer machine to transfer the exquisite pattern on the transfer film to the surface of the product in one process (heating and pressurizing). After molding, the ink layer and the product surface are melted into one, which is realistic and beautiful, greatly improving the grade of the product. However, due to the high technical content of this process, many materials need to be imported.

The thermal transfer process is applied to the surfaces of various ABS, PP, plastics, wood, coated metal and other products. Thermal transfer can be designed and produced according to customer requirements. Thermal transfer film, the pattern is transferred to the surface of the workpiece by hot pressing to improve the grade of the product. Thermal transfer technology is widely used in plastics, cosmetics, toys, electrical appliances, building materials, gifts, food packaging, stationery and other industries. The equipment used in thermal transfer technology includes: cup baking machine, cap baking machine, baking tray machine, direct pressure heat press machine, shaking head heat press machine, etc. The consumables required are professional thermal transfer paper and thermal transfer ink, plus printers, computers, and digital cameras to do the thermal transfer process.
