How To Choose The Correct Thermal Cash Register Paper?

What is the use of thermal cash register paper?

First of all, we have to understand that this type of paper is widely used in hotel catering systems, shopping mall POS terminal systems, telecommunications systems, medical systems, banking systems and other fields. It is mainly made by applying fine particle powder on plain paper. The components of these powders are mainly leuco dyes such as phenols or other acidic substances, which are separated by a film. Under heat, the film melts and the powder mixes to develop a color reaction.

Moreover, the thermal paper is generally divided into three layers, the bottom layer is a paper base, the second layer is a heat-sensitive coating, and the third layer is a protective layer, and the heat-sensitive coating or protective layer is mainly affected by the quality thereof. If the coating of the thermal cash register paper is uneven, the color of the printing will be uneven when printed; 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 layer is also critical for the shelf life after printing, which absorbs some of the light that causes the thermosensitive coating to react chemically, slowing the deterioration of the thermal cash register paper.

When using the thermal paper, the profitable writing tool should pay attention to the fact that the color writing on the thermal paper is unstable and easy to fade, which makes the file content difficult to read. Our commonly used lottery tickets are generally thermal cash register paper.

How to choose the correct thermal cash register paper?

First of all, you should carefully observe the appearance of the paper. If you find that the paper is very white, you should pay attention to this type of paper. Because the paper is too white, it is because the protective coating and the thermal coating are unreasonable, and too much phosphor is added. Better paper should be slightly greenish. The paper finish is not high or looks uneven, indicating that the paper coating is uneven. If the paper looks very reflective, it adds too much phosphor and the quality is not good.

Secondly, you can choose to use fire to bake, that is, you use a lighter to heat the back of the paper. If it is heated, the color on the paper is brown, indicating that the heat-sensitive formula is not reasonable and the storage time may be short.

Even you can use sunlight to compare and identify, print the printed paper with a highlighter and put it in the sun. The paper which turns black at the fastest can be preserved shortest.
