Smoothness of printing paper for handbag: smoothness is the most important printing performance of paper. Which printing method is not wet. The outline of the printed bag and the image printed on smooth paper are clearly visible. This is because the smooth paper can better contact with the printing plate, so you can get the ink on the printing plate. These layers are evenly transferred to the surface of the paper. Due to the instability of the paper surface, the paper with low smoothness can not contact the printing plate evenly, and the ink layer can not be transferred to the paper surface well, which leads to the false printing and affects the printing quality.
Moisture content of printing paper for handbag: the moisture content of printing paper for handbag will also affect the printing quality. If there is more water in the paper, the strength of the paper will decrease. Under the action of external force, the fiber is pulled out and the plasticity is enhanced, which affects the drying speed of the imprint. If the water content of the paper is too small, the paper will be brittle, easy to cause damage, and handbag printing will also produce static electricity.
Ink absorption of paper: ink absorption of paper refers to the degree of ink absorption of paper. The more ink paper absorbs, the more ink paper absorbs, and vice versa.
The absorptivity of paper to ink mainly depends on the size of the gap between the paper fibers, that is, the compactness of the paper. If the space between the paper fibers is too small, ink absorption will be very poor, and vice versa. In the printing process, the ink absorption of the paper should be moderate. Because when the paper ink absorption is too small, it is easy to appear unclear or not obvious, too often produce mold burn, through printing phenomenon.
