The effect of static electricity on print quality

1. Affect the printing quality of the product The first is the surface of the substrate charged, such as paper, polyethylene, polypropylene, cellophane, etc. They will absorb paper dust or a lot of dust, impurities, etc. floating in the air, thus affecting the transfer of ink, so that the print Flowering, etc., caused the quality of printed matter to decline.

Second, the ink is charged. If the charged ink is discharged during the move, it may appear as “static ink spots” on the printed matter. It looks like the ink is not very active and the ink is not evenly distributed. This is often the case in thin-layer printing. Happening. In the field printing, if the charged ink is discharged on the edge of the printed matter, it is easy to cause "ink whiskers" on the edges.

2. Influencing the safety of production In the printing process, due to high-speed friction, peeling can generate high static electricity. When static electricity accumulates, it easily leads to air discharge, resulting in electric shock or fire. When the voltage is high, the charged ink may cause the ink, solvent to catch fire, or shock the staff through the ink, directly threatening the safety of the staff.
