Simply Analyze the Effect of Filler on the Performance of Printing Paper

The addition of fillers to printing paper can improve the printability of the paper, such as increased paper whiteness, smoothness, opacity, and stiffness. Improves the affinity, softness, and stability of paper for ink, which helps improve the quality of prints. Of course, too much filler added to the paper also brings some undesirable effects. The main manifestations are the decrease of the paper strength and the decrease of the sizing effect. In the printing, the phenomenon of falling powder and hair loss occurs easily. The filler particles are transferred to the printing plate and the eraser. There will be scumming and other phenomena on the cloth; due to the friction of the filler, the printing plate will be worn out, but filling with precipitated calcium carbonate can reduce the wear plate to a minimum.
