How to Choose Thermal Cash Register Paper?

Cash register paper, as the name implies, refers to the paper roll used in the cash register to record cash register details. It is mainly used to provide customers with a list of shopping details and can be replaced after use. Generally, the material of the cash register paper is the corresponding material suitable for the internal printing parts of the cash register. For ordinary stylus printers, ordinary 1-3 layers of printing paper can be used for printing; for thermal head printers, only thermal printing paper can be used for printing.

Ordinary cash register paper and carbon-free cash register paper are produced and processed by double offset paper. The quality of cash register paper depends on the quality of the double offset paper used. In order to achieve a better use effect, first look at the material. The paper with white surface and no impurities is generally wood pulp paper. The cash register paper produced has better tensile strength and clean appearance; paper made of mixed pulp paper or straw pulp paper has more or more There are few noises. Obviously, the pulling force is also poor, and it is easy to break during printing; in fact, it is smoothness. Cashier paper with better smoothness can reduce the wear of the print head and achieve better printing results.

Thermal cash register paper is a printing paper specially used for thermal printers. Its quality directly affects the print quality and storage time, and even affects the service life of the printer. Thermal cash register paper is generally divided into three layers, the bottom layer is a paper base, the second layer is a thermal coating, and the third layer is a protective layer. The thermal coating or protective layer mainly affects its quality. If the coating of the thermal cash register paper is not uniform, printing will result in different shades of color; if the chemical formula of the thermal cash register paper coating is unreasonable, the storage time of the thermal cash register paper after printing will be shortened. The protective layer is also critical to the storage time after printing. It can absorb part of the light that causes the chemical reaction of the thermal coating to slow down the deterioration of the thermal cash register paper.

The method of identifying thermal cash register paper: Firstly, look at the appearance of the paper. A good quality thermal cash register paper has uniform color development, good smoothness, high whiteness, and a little greenish color. If the paper is very white, the protective coating and thermal coating of the paper are unreasonable, and too much phosphor is added. If the paper is not smooth or looks uneven, then the paper coating is uneven, if the paper looks reflective The light is very strong and too much phosphor is added. Secondly, bake with fire and heat the back of the paper with fire. If the color that appears on the paper is brown, it means that the heat-sensitive formula is not reasonable and the storage time may be relatively short. If the black part of the paper has small streaks or color blocks Uneven, indicating uneven coating. The paper with better quality should be black and green after heating, and the color block should be uniform, and the color gradually fades from the center to the surroundings.
