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.
