In the silk screen printing machine, the screen printing screen can not be decontaminated, but we often use silk screen printing machine to screen different kinds of products, resulting in frequent cleaning of the screen dirt is not clean, the result This has caused waste, affected printing quality and shortened the service life of the template. This article will introduce you to the screen printing machine tuning skills.
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.
More user-friendly screen printing machine manufacturers: humanized operation of the screen printing machine, can make a technician easier to get started, so that the operation is mature in the shortest time, a good screen printing machine, the first time to adjust a common screen printing machine A technician may take up to 30 minutes, but with a user-friendly, flexible machine, a technician may be able to adjust and enter the production phase in 10 minutes.
