Just like buying a mobile phone, many friends will find that the price of the screen printing machine is also uneven. The price of the same type of screen printing machine will be very different. This difference is even big, so why do you look like a screen printing machine? , its price will be so different, this article will introduce you to the second-hand automatic screen printing machine offer. 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 serious 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, so as to avoid blocking. In the selection of ink, the climate 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 ink on the surface of the screen printing machine, and replace the ink with high viscosity. 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. By selecting a high-mesh screen and a high-resolution photosensitive material, the thickness of the flat screen printing plate can be ensured to be uniform, and the occurrence of defects can be reduced. When cleaning a circular screen printer, different situations are encountered. Due to the design structure, it is not possible to wash the dirt on the absorbent paper like a conventional screen printer. Fortunately, due to the faster printing speed, it is less likely that the ink will dry in the mesh. Article source address: http://
