Screen printing is one of the most popular printing methods in the modern era. It can be understood as the screen printing mesh method of hanging the sky. It is more convenient and easy to operate. Screen printing is also common in glass. Because you can print interesting and vivid patterns and texts on the glass. The way glass printing was used has been eliminated, and its method of operation is a waste of time and manpower. And the efficiency is also extremely low.
Today's glass-etched screen printing screen printing process makes etching easier and less time-saving. There are two kinds of silk screen etching processes:
1, cold printing. Glass silk screen etching can also be carried out using a cold stamping method. The resist print can be made of a special asphalt paint plus a resist powder, or a commercially available anti-ink can be purchased. After the printing is completed, the hydrofluoric acid is corroded after the resist film is completely dried. Cold stamping is suitable for etching of individual patterns.
2, hot stamp. The hot stamping method for glass silk screen etching is to add a small amount of anti-corrosive powder to a binder prepared by paraffin, asphalt, stearic acid, etc., and prepare a resist printing material by hot stamping screen printing, according to the design pattern. The printed material is smeared onto the surface of the glass to form a resist film. The portion of the resist film on which the glass is exposed, that is, the pattern to be etched. The etching is carried out using chlorofluoric acid, and after etching, the resist layer printed on the glass is washed away with boiling water. Hot stamping is suitable for etching suitable for two-sided continuous, tetragonal continuous pattern patterns. ,
In addition to the above glass etching screen printing screen printing process, there are other methods of glass ice pattern silk screen printing, glass frosting silk screen printing, glass silk screen ion exchange coloring method, and the like. Here Xiaobian is a relatively common screen printing network. I want to make my glass products more quality and improve economic efficiency. I need to change my old way of printing.
