The main materials for screen printing are nylon mesh and polyester mesh. Although the current polyester material has been widely used. Screen printing and other printing methods are basically the same. It is necessary to control more parameters in screen printing. The actual printing is quite simple. From cloth, mesh, screen frame to the tension of the screen, these must be determined according to the needs of the printed matter.
In the actual use of screen printing, nylon mesh printing screen and polyester screen. According to the actual investigation, it is found that more nylon printing meshs are currently used.
Due to its dimensional stability, polyester screen printing screens are very suitable for printing jobs requiring high
register accuracy, such as printed circuit boards. The disadvantages of nylon mesh printing screens are elongation and poor tension retention. After a period of use, the tension of the screen will weaken, and the screen will be loosened, and the printing accuracy will be reduced. Therefore, the nylon mesh printing mesh is not suitable for printed circuit boards and other fine products.
Screen printing is a wet printing process, and certain absorption of moisture must be considered. Nylon materials absorb up to 5% of moisture, while polyester meshes stretch 19% to 23% before breaking.
