How do I determine the screen printing mesh pitch?
What is the screen printing mesh distance? An important indicator in the screen printing process is the screen distance, in layman's terms, the screen distance is "the distance between the screen printing mesh and the substrate", you must not underestimate this screen distance, if not set properly will cause a lot of screen printing failure, today Duoyang Screen Printing will tell you how to determine the screen printing mesh and what conditions will occur if not set properly Today, DuYan Screen Printing will tell you how to determine the screen and what will happen if it is not set properly.
What do we base on to determine the screen distance?
4. the surface material of the screen printing item
5. the thickness and viscosity of the ink
6. the size of the inner warp of the screen printing mesh plate.
As can be seen from the above screen distance due to the diversity of the printing environment, and set the mesh distance should be different, due to the different viscosity of the ink, if the smoother surface, the mesh distance should be appropriately increased, if the screen printing plastic and other items require high precision, the mesh distance should be adjusted appropriately small, the general mesh distance should be controlled between 2mm-6mm.
What problems will occur if the screen distance is not appropriate
Screen distance is too large: due to screen printing mesh plate tension restrictions, the screen distance will be too large will cause printing graphics blurred, overflowing ink phenomenon.
Screen distance is too small: will cause the screen printing mesh plate in the printing is completed when lifted and printed text friction and cause the phenomenon of ink pulling and printing is not fine.
