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 high, so the small amount of ink, the greater the deformation of the scraper, it will have a great influence on oil filling state, will also make network version of the deformation increases, and the friction between the blade and screen also increases, increase the attrition of silk screen already so, also affects the line of printing speed.
