There are many manufacturers of screen printing meshs, some are merchants, some are middlemen. Business is an important issue affecting quality, but the reason for affecting quality is not this one. There are still many influencing factors.
Maishi experts teach you solutions:
1. Carefully analyze the causes of the quality impact, and solve the problems caused by the causes. As for the quality problems caused by non-scratch operations, such as stretcher problems, optimal distance problems, silk screen stencil problems, workpiece surface treatment problems, and printing materials selection. Matching and so on will affect the quality of silk screen printing.
2. A solution to the problem with patterns or lines. The printing material is too thin, and the printing force is too strong; the printing material is not evenly adjusted; the solvent or cleaning agent on the net mold is not dry after the netting, or the surface cleaning agent is not
dryor dirty when the workpiece is reworked; After the squeegee printing, the printing net sealing force is too large, so that a small amount of printing material is extruded into the mesh; the moving speed of the squeegee in the printing is too different within the effective area of the printing material, pause or repeat printing, etc.; The degree does not match the selected mesh size.
3, the surface of the substrate is not clean, and there is oil; the printing material is too sticky, the dirt on the net mold is not removed, the particles of the printing material are large, the mesh of the high mesh is not passed; the drying speed of the silk screen is too fast, and the screen printing mesh workplace is exhausted; The quick-drying printing material failed to seal the net in time to produce a netting; the unevenness of the printing was uneven, or large or small; the surface of the substrate was uneven。
