What problems should be paid attention to when printing nozzle bags?
1. The temperature and humidity of the printing workshop will affect the drying speed of the ink: if the humidity is too high or the humidity is too low, the drying speed of the ink will be accelerated. .
2. Problems with gravure printing equipment: If there are some problems in the design of the gravure printing equipment, such as the large diameter of the cylinder, the shallow immersion of the printing plate cylinder in the ink tank, etc., the hot air leaking from the drying box will blow the printing plate directly. The layout then causes the ink to dry in the cells, causing the layout to clog. In addition to laundry detergent packaging bags, the printing of various plastic flexible packaging should also be paid attention to. For factories integrating design, plate making, printing, compounding, and bag making, it is necessary to pay more attention to the adverse effects of some details.
3. Ink drying speed: When the ink dries too fast, a part of the ink will form a film before it is transferred to the printing substrate. The poor solubility of the ink film will inevitably lead to poor ink transfer. Plate blocked.
