The piled plates caused by de-powdering on the surface of the paper appear honeycomb gypsophila, caused by the shedding of countless fillers, glues, pigments, and auxiliary materials, which seriously affects the quality of printed products. It takes one scrubbing plate once to print about 1000 sheets The reason is similar to that of paper piles, which is mainly caused by the de-powdering of the paper caused by the loose fiber structure on the surface of the paper. This phenomenon is mainly due to the poor printing quality of the paper. However, the solution is different. The specific gravity of paper wool and powder is different. The large area of ​​paper wool is light and the powder is extremely fine and heavy.
Solution:
Increase the fluidity of the ink, add a relatively thinner ink to the ink, increase the viscosity of the ink and the amount of ink delivery, increase the amount of ink stored on the ink roller, and deepen the color of the blotting ink. In addition, you can add a pad under the printing plate The thickness of the paper increases the printing pressure.
