Glass screen printing materials need how to choose?

Glass is widely used in our lives, there are many kinds of glass, and its performance and material characteristics are not the same, but the glass needs screen printing in the production process, when the screen printing glass, the glass screen printing material needs how to choose? Let's get to know each other.

1, suitable for printing glass

According to the user's requirements, the glass can be cut in regular shape or irregular shape, and then the edge grinding, cleaning, drying and waiting for use. Special attention should be paid to the fact that there should be no water marks on the glass surface.

2, the choice of wire mesh

The screen plate for glass printing is the same as the general screen plate, and the glass screen plate uses synthetic fiber screen, stainless steel screen, and natural fiber screen. When printing general color, the above screen can be, generally choose cheap synthetic fiber screen, as gold and silver decoration, you can not choose stainless steel screen, screen specifications generally use 270 ~ 300 mesh.

3, the choice of mesh frame

At present, the more regular and deformation of the mesh frame is an aluminum alloy mesh frame, and its size should be larger than the pattern, and the specific size should be the outer edge of the pattern from the mesh frame should be between 70 and 100mm. In addition, the strength of the mesh frame is very important, and the key is that the horizontal rigidity is enough.

4. Stretch the net

Choose the mesh and the mesh frame, and combine the two, which is the stretched net. There are many ways to stretch the net, you can use manual, mechanical, pneumatic methods, the current more advanced, can stretch high quality screen is the pneumatic stretching machine. The requirements of the stretched net are uniform tension, the longitude and latitude lines of the net remain vertical, and the adhesive should be firm and not slack.
