3 Paper quality
Paper as a printing material, its quality has a direct impact on the quality of printing and printing plate printing rate. If the paper quality is not good, the surface strength of the paper is poor, and the phenomenon of powder dropping and pulling is liable to occur during the printing process. After the paper powder and paper hair adhere to the ink roller or the water roller, the normal ink absorption, ink application, and water absorption are affected on the one hand. And the effect of water transfer, on the other hand, attached to the ink roller or water roller on the impurities will increase the friction of the printing plate, and even adhere to the printing plate, resulting in off plate and paste the ills.
