The industry used by Polyester Screen Printing mesh is very much. Pinholes may also occur during use. How can we deal with it?
The regular manufacturer maishi of polyester printing mesh gives us help:
1. When making plates, there will be some sol in the wash and development. In addition, when the emulsion is applied, dust is also mixed in, and pinholes are formed by adhering to the screen. These can be found and can be repaired in time when the test is carried out. If dust and foreign matter adhere to the screen, blocking th
e screen opening will also cause pinholes. Before the official printing, if you use a strong ink-absorbing paper, after several printings, you can remove the dust from the plate.
2. Cleaning and detergent may mix oil and broken fibers. Pinholes may be dust and
other debris on the screen. Aluminum plates, glass plates, acrylic plates, etc. should be printed immediately after pre-treatment before printing. In multicolor printing, a method of rubbing with alcohol before printing is generally employed. In addition, semi-automatic and fully automatic ultrasonic cleaners can be used. Pre-treatment removes dirt such as grease and, at the same time, removes dust adhering to the surface.
The above is the pinhole phenomenon that may be seen when the maishi manufacturer provides us with the printing of polyester. It is worth reminding that there is a lot of complexity when printing, so we need to combine the actual situation when we think about the problem.
