Screen printing process

The ink is printed to the surface of the glass, and then the ink curing measures are used, and the printed pattern is strong and durable.

The process flow is as follows: sizing→ sizing→→→ drying developing→ drying ↓ flat glass → cutting→ edging→ cleaning and drying→ printing sintering

1. Suitable for printing glass According to user requirements, cut the glass, which can be regular shape or irregular shape, and then inverted edge grinding processing, then washing, drying for use. Special attention should be paid here that there should be no water traces on the glass surface.
2. Selection of screen Screen printing plate for glass printing is the same as general screen printing plate, and the glass screen printing plate adopts synthetic fiber screen, stainless steel wire mesh, and natural fiber wire mesh. When printing general pigments, the above wire screens can be used, generally using cheap synthetic fiber wire mesh; When used as gold and silver decoration, stainless steel wire mesh cannot be selected. The specifications of wire mesh generally use 270~300 mesh.

3. The choice of mesh frame is currently more formal, the deformation of the mesh frame is aluminum alloy mesh frame, its size should be larger than the pattern, the specific size should be the outer edge of the pattern should be between 70~100mm from the mesh frame. In addition, choose the mesh frame, its strength is very important, the key is that the horizontal rigidity is sufficient.

4. The bandage net chooses the wire mesh and the mesh frame, and combines the two, which is the bandage net. There are many ways to bandage the net, you can use manual, motorized, pneumatic methods, the current more advanced, can stretch high-quality mesh plate is pneumatic bandage machine. The requirements of the bandage net are uniform tension, the warp and weft lines of the mesh are kept vertical, and the adhesive should be firm and not relaxed.
