Silk screen glass in the process of selection of stretched screen: using the correct stretched screen process, screen tension uniform stability is very important, tension changes will affect the ink through the degree of difficulty, resulting in the change of dot shape. If the screen tension is not uniform, in screen printing, ink will produce different penetration. Dot will produce different deformation in different areas and appear moire. In order to ensure the accuracy of overprint and the stability of screen printing process parameters, four-color screen screen printing requires four screen screen tension not only to reach an appropriate level, and the tension value should be consistent as far as possible, just stretched good net can not be immediately applied to production, to be placed for more than two days, so that the tension tends to be stable. The choice of mesh size should also be consistent and the best choice of metal mesh frame. At the same time, ensure that the mesh and the mesh frame as horizontal and vertical as possible.
