Dust-free thermal paper for Xinlitai supermarket cash register

The small receipt thermal paper is used for cash register printing receipts. It is a special printing consumable. What is the difference between it and the general paper we use in our daily life? Editor Today Let's analyze it for everyone.

The principle of thermal paper is to coat a general paper base with fine particles, which are composed of leuco dyes, phenols or other acidic substances, separated by a film. When heated, the film melts and the powder mixes to cause a color reaction.

Thermal paper is a printing paper specially used for cash registers. Its quality directly affects the printing quality and storage time, and even affects the service life of the cash registers. The thermal paper on the market now has mixed good and bad, and the country has not issued relevant policies. Many users are not clear on how to distinguish the quality of thermal paper. This has provided many merchants with inferior thermal paper supply convenience, which constitutes a loss for users. The light storage time is shortened, the handwriting is blurred, and the heavy damage to the printer.

The thermal printing paper used in cash registers on the market 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 is the first to affect its quality. Or protective layer.

If the coating of the thermal paper is uneven, it will cause the color to be dark in some places and light in some places during printing, and the print quality will be significantly reduced. If the chemical formula of the thermal coating is unreasonable, it will cause the printing paper The storage time becomes very short. Good printing paper can be stored after printing.(under normal temperature and avoiding direct sunlight)5years, Nowadays, there are more long-lasting thermal papers that can be stored 10, but if the formula of the thermal coating is unreasonable, it can only be stored for a few months.

The protective coating is also very important for the storage time after printing. It can absorb some light that causes the thermal coating to react chemically, slow down the degradation of the printing paper, and can protect the thermal element of the printer from harm, but if it is protected The uneven coating will not only greatly reduce the protection of the thermal coating, but even the fine particles of the protective coating will fall during the printing process, which will interfere with the thermal element of the printer and cause damage to the thermal element of the printing.
