In the bag customization, a variety of logo production processes are often used, and the thermal transfer process is a popular pattern printing process in recent years.
Thermal transfer is an emerging printing process that has been introduced abroad for more than 10 years. The printing method of the process is divided into two parts: transfer film printing and transfer processing. The transfer film printing adopts dot printing (resolution up to 300 dpi), and the pattern is pre-printed on the surface of the film. The printed pattern is rich in layers, colorful, and ever-changing. The color difference is small, the reproducibility is good, the effect of the design pattern can be achieved, and it is suitable for mass production.
The transfer processing transfers the delicate pattern on the transfer film to the surface of the product through one-time processing (heating and pressing) of the heat transfer machine. After the molding, the ink layer is integrated with the surface of the product, which is realistic and beautiful, greatly improving the grade of the product.
