Common cash register paper and carbon - free cash register paper with double - adhesive paper production and processing, the quality of the cash register paper depends on the quality of the double - adhesive paper; In order to achieve a better use effect, first look at the material, the surface of the white paper without impurities is generally wood pulp paper, the production of cash register paper tension is better, clean appearance; The paper with mixed pulp paper or straw pulp paper has more or less miscellaneous spots on it. Obviously, the pulling force is also poor, and it is easy to break during printing. In fact, the paper with better smoothness can reduce the wear of the printing head and achieve better printing effect. 

Thermal cash register paper is a kind of printing paper specially used in thermal printers. Its quality directly affects the quality of printing and storage time, and even affects the service life of printers. Thermo-sensitive cash register paper is generally divided into three layers, the bottom layer is paper base, the second layer is thermal sensitive coating, and the third layer is protective coating, which mainly affects its quality. If the coating of the heat-sensitive cash register paper is not uniform, the color of the printing will be different when printing. If the chemical formulation of the coating on the thermal cash register paper is unreasonable, the storage time of the thermal cash register paper will be shortened after printing. The protective layer is also critical for the preservation time after printing. It can absorb part of the light that causes the chemical reaction of the thermos-sensitive coating and slow down the deterioration of the thermos-sensitive cash register paper.

Method for identification of heat sensitivecash register paper: First of all, look at the appearance of the paper. Good quality heat-sensitive cash register paper has uniform color, good smoothness, high whiteness and a little green. If the paper is very white, the protective coating and thermal coating of the paper are unreasonable and excessive phosphor is added. If the paper finish is not high or looks uneven, then the paper coating is uneven. If the paper looks very reflective, it also adds too much phosphor. Secondly, bake with fire and heat the back of the paper. If the color of the paper is brown, the heat-sensitive formula is not reasonable and the storage time may be shorter. If the black part of the paper has fine stripes or uneven color patches, the coating is uneven. The paper of better quality should be black-green after heating, and the color block is uniform, and the color gradually fades from the center to the surrounding.
