Effect of Surface Sizing on Printing Paper Properties

1 increase the paper's water resistance and surface strength, can reduce offset printing paper in the phenomenon of hair loss;

2 Improve the printability. If the surface material is too small, the printing paper will absorb too much of the link material in the ink, causing the print to be dull. On the other hand, if the amount of surface material is too much, the drying rate of the ink will be slowed, resulting in smearing and bright stains;

3 increase the scratchability of the paper, surface sizing can reduce the penetration of ink, so it is easy to wipe off the ink, increasing the paper's anti-friction ability;

4 increase the strength of the paper, such as burst, bending and tensile strength; 5 reduce the two sides of the paper and deformation.
