How to choose printing mesh for glass printing?

On the one hand, we must be familiar with the technical requirements of different products. On the other hand, we must understand the technical parameters of the screen and its influence on the screen printing effect. By understanding the structure and physical properties of the printing mesh and its performance attributes. Make the right choice.

Common glass screen printing products include: automotive side window and windshield decorative screen printing, architectural curtain wall glass label screen printing, home appliance furniture glass decorative panel screen printing.

In order to achieve reasonable screen printing results according to different process requirements, we must pay attention to the following points.

For glass printing, the printed surface should be flat and even, mainly made of polyester mesh. Polyester screen can be used for printing accuracy, print resistance, acid and alkali resistance and organic solvent resistance. Meet the requirements of glass printing.

As far as the color of the printing net is concerned, there are currently two main types on the market, one is white and the other is yellow. The white polyester mesh reflects and scatters light during exposure, and the ultraviolet light diffuses to the edges of the image to expose the photoresist film. For fine line and shade printing on glass, since the glass surface is a non-absorbent surface and the material is transparent, it is preferred to use a white screen for plate making. However, defects such as the jagged edges of the lines after white screen printing and the differential resolution of the tonal images are more pronounced. The yellow screen prevents light from scattering during exposure, which helps maintain the sharpness of the edges of the image. Therefore, the yellow screen can be used to print solid color block patterns and general graphic lines for thin lines requiring high precision, such as automobiles. Rear windshield heating line printing, home appliance panel glass logo printing, decorative glass tone pattern printing, etc., we recommend using a yellow screen for plate making.
