In catalogue printing process, printing and fading should be noticed. If the ink in the ink pan contains moisture, dust and incompatible solvents to enter the ink, these substances will not only gel, but the gelatinization ink will not only reduce the binder content, but also reduce the adhesion of the ink. Pigment causes uneven distribution of pigment in ink, and can not be used on the upper roller. If the whole ink is light, the quality of the ink is problematic.
