The Quality Of Thermal Cash Register Paper Directly Affects The Printing Quality And Storage Time

Thermal cash register paper is a kind of printing paper specially used for thermal printer. Its quality directly affects the printing quality and storage time, and even the service life of the printer. The thermal cash register paper is generally divided into three layers, the bottom layer is the paper base, the second layer is the thermal coating, and the third layer is the protective layer. The thermal coating or protective layer mainly affects its quality. If the coating of thermal cash register paper is uneven, it will lead to different color depth during printing; If the chemical formula of the coating of the thermal cash register paper is unreasonable, the storage time of the thermal cash register paper after printing will be shortened. The protective layer is also key to the storage time after printing. It can absorb part of the light that causes the chemical reaction of the thermal coating and slow down the deterioration of the thermal cash register paper.
