Prepress preparation: In order to achieve good printing results, screen production must be done. The tension of the mesh, the stability of the mesh frame, the error of the pattern making can not exceed 0.05mm. Mesh mesh can be more specific requirements, choose the right mesh, appropriate when some nets also need to do 45 degrees of cable-stayed plate.

High temperature ink needs to reflect good adhesion after glass tempering.

The printing requirements are relatively high, requiring that half perspective window has no fine particle points, no scraper pull lines, and the required transmittance index can not change too much.
