The correct choice of screen in glass screen printing (3)

Today, I will continue to introduce you how to choose the right screen printing mesh for glass. However, this article is the last one. I hope these three articles can solve some problems for you. If you have other problems, please feel free to contact us.

The opening of the screen mesh is mainly for two aspects. The one hand is the uniformity of the screen opening. The opening of the screen can be observed with a high magnification magnifier. The ideal screen opening is square and Uniform size, the opening of the low-quality mesh mesh will have irregular shape and inconsistent size; on the other hand, the size of the mesh opening, when using some special ink with larger particles, in order to meet the printing of ink Suitability, the opening size of the mesh mesh must be considered. The opening size of the mesh is three times that of the solid particles of the ink. The stability of the printing screen tension of the large-area solid color ink on the glass surface is relatively required. Not high, the printing of such products is mainly two aspects: the mesh number and the wire diameter of the screen. If the mesh size and the wire diameter are too thick, the glass surface is not absorbent to the ink after printing, which is not conducive to the ink surface. Smooth and flat, the surface of the ink film is left with a silkscreen imprint; if the mesh number and the wire diameter are too thin, it is difficult to ensure the thickness of the ink layer during printing, and it can only rely on the plate when making the plate. Increasing the thickness of the photosensitive film to increase the thickness of the ink layer after printing. After printing, the ink layer is too thin, and the hiding power of the ink is not guaranteed. According to our many years of production experience, the solid color block printing is performed on the glass surface, and the screen is used. The screen printing effect was 180 mesh, the wire diameter was 50 mm, and the screen printing with an opening of 91 mm was the best.

In order to choose the screen suitable for itself, it is only one aspect to consider the technical parameters and performance indicators of the screen. On the other hand, we must also consider the minimization of production cost, in the case of satisfying the customer's requirements for printing quality. Choose a more affordable screen from a wide range of screens.

Whether the screen tension of the screen tension stability has a stable tension has a great influence on the printing effect, we recommend using a screen with a stable tension. To determine the stability of the tension of two different screens, the following test can be used to use the same aluminum frame and the same mesh of mesh and wire diameter. The screen is the same as before the separation.
