2. Screen printing mesh selection
The screen plate used for glass printing is the same as the general screen plate, glass silk printing plate selection of synthetic fiber screen, stainless steel wire mesh, natural fiber screen. When printing general colors, the screen can be, generally choose cheap synthetic fiber screen. Mesh specifications generally 270 ~ 300 mesh. As gold and silver decoration, can’t choose stainless steel wire mesh.
3. Selection of mesh frame
At present, the more regular, small deformation of the mesh frame is aluminum alloy, its size should be larger than the pattern, the specific size should be the pattern of the outer edge of the mesh frame should be between 70 ~ 100mm. In addition, the choice of mesh frame, its strength is very important, the key is the horizontal direction of the rigid enough.
4. Stretching mesh
Selects the screen printing and the mesh frame, combines the two, this is the stretching mesh. There are many ways to stretch the mesh. Manual, motor and pneumatic methods can be adopted. At present, the more advanced stretch high quality screen plate is pneumatic stretch screen machine. The stretch of the mesh is uniform, the mesh's warp and weft lines are kept vertical, and the mesh glue should be firm and can not be relaxed.
5. The printing
Plate glass printing machine has manual, semi-automatic, automatic several types. Manual printing machine is suitable for small batch, small specifications of flat glass. Semi-automatic and full-automatic printing machines are suitable for large quantities and large specifications of multi-color printing, with the advantages of accuracy and speed. The largest semi-automatic printing press can print glass in the size of 2000×1500mm. Automatic printing presses are generally used for printing car windshields.
