Generally, glass can be divided into physical tempering and chemical tempering. However, for the printing industry, the printing processes of both have many things in common, and the same glass screen printing machine production line can be used to completely screen the glass printing process. You introduce the price of the flat screen dual-use screen printing machine.
Screen printing machines are prone to failure when printing, some are unilateral reasons, but more are complicated reasons, so the operator of the flat screen printing machine should pay special attention to the cause of the failure, so as to take corresponding countermeasures.
1. Blocking, that is, the part of the image with mesh can not transfer ink during printing. This phenomenon will affect the printing quality. In severe cases, normal printing will not be possible.
The solution adopted is as follows: change the printing material that is not easy to drop powder, reduce the viscosity of the ink, thereby avoiding blocking. When selecting the ink, the weather influence should be considered, the viscosity of the ink should be appropriately reduced, and the fluidity of the ink should be improved.
2. The ink does not adhere to the substrate of the flat screen printing machine
Solution: Regularly clean the flat screen printing machine to remove oil and dust, corona and plasma on the surface of non-polar products, improve the adhesion of the ink on the surface of the screen printing machine, and replace the ink with high viscosity, when appropriate. You can add new ink.
3. Ink film edge defects, when printed with a flat screen printing machine, the edge of the saw is broken, the general quality of the screen printing plate, the edge should be smooth.
The thickness of the flat screen printing mechanism plate can be ensured by selecting a high-mesh screen and a high-resolution photosensitive material to reduce the occurrence of defects.
Of course, different glass products have different printing processes, so our glass screen printing machine production line plan will also change, so it is determined by the customer's actual situation, because some customers only need to print a pattern on the glass screen. The customer is required to print a variety of colors, then at this time, the entire machine has to be redesigned to fully meet the customer's product printing process needs.
