Screen material selection
Currently the most used nylon mesh and polyester mesh.Nylon wire mesh heat resistance is poor, heat is easy to produce thermoplastic deformation, so that the tension is not uniform, affecting the quality of screen printing.Bonded wire mesh or screen template production is not suitable for high te...Read more -
How to control the pressure in screen printing?
Answer: the effect of pressure is to ensure network edition and printing surface full line contact, under the premise the as small as possible. Because of the pressure, the greater the scraper, though a good contact with the screen, but the mesh flattening and scraper embedded net hole degree is ...Read more -
