Thermal transfer printing is a new printing technology, which has been introduced from abroad for more than 10 years. The printing method of this process is divided into two parts: transfer film printing and transfer processing. The transfer film is printed by dot printing (resolution up to 300dpi), and the pattern is printed on the surface of the film in advance. The printed pattern is rich in layers, colorful, ever-changing, with small color difference and good reproducibility, which can meet the requirements of designers and is suitable for mass production. In the transfer printing process, the exquisite patterns on the transfer printing film are transferred to the product surface through one-step processing (heating and pressurizing) by a thermal transfer printing machine, and the molded ink layer is integrated with the product surface, which is vivid and beautiful, and greatly improves the product grade.
Screen printing belongs to stencil printing, and it is called four printing methods together with lithography, gravure printing and gravure printing. Stencil printing includes copying stencil, engraving stencil, stencil printing and screen printing. The principle of stencil printing is that when printing, the ink is transferred to the substrate (paper, ceramics, etc.). ) pass through the perforation of the template with a certain pressure to form an image or text.
The screen is squeezed by the scraper, so that the ink is transferred to the substrate through the mesh of the graphics part, forming the same graphics as the original. Screen printing equipment is simple, easy to operate, simple in printing and plate making, low in cost and strong in adaptability.
