Thermosensitive cash register paper is a roll type printing paper made from thermal paper as raw material through simple production and processing. So, do you know that general printers can print thermal cash register paper? How to choose thermal cash register paper? Let me introduce you in detail later! Can a typical printer print thermal cash register paper? Of course not, it must be a thermal printer. Moreover, the small notes printed by thermal printers are not easy to store, and as they grow, the words on top slowly disappear. However, thermal printers print relatively quickly.
The following is the selection method for thermal cash register paper: Thermal cash register paper is specifically used for printing paper on thermal printers, and its product quality directly affects the printing quality and storage time, and even affects the service life of the printer. The thermosensitive cash register paper can generally be divided into three layers, with the bottom layer being the paper base, the second layer being the thermosensitive coating, and the third layer being the protective layer. The key factor affecting the quality of its products is the thermosensitive coating or protective layer.
If the coating of the thermosensitive cash register paper is uneven, it will cause different color tones and shadows during the printing process; If the organic chemical composition of the coating on the thermosensitive cash register paper is unreasonable, it will cause a reduction in the storage time of the printed thermosensitive cash register paper. The protective layer is particularly important compared to the storage time after printing. It can absorb some light, which can cause chemical changes in the thermosensitive coating and alleviate the deterioration of the thermosensitive receipt paper.
The method for distinguishing thermal sensitive cash register paper: The first step is to check the appearance of the paper. High quality thermosensitive cash register paper has uniform hair color, good smoothness, high whiteness, and a slight emerald green tint. If the paper is very white, then the protective coating and thermosensitive coating on the paper are unreasonable, and too much fluorescent powder is added. If the smoothness of the paper is not too high or looks uneven, then the coating on the paper is uneven. If the paper appears to reflect light strongly, then too much fluorescent powder is also added.
Afterwards, bake over fire and heat the opposite side of the paper with fire. If the color tone appears brown on paper, it indicates that the thermal secret recipe is unreasonable, and the storage time is likely to be reduced. If the black part of the paper page has fine stripes or uneven color blocks, it indicates that the coating is uneven. High quality thermosensitive cash register paper should turn black green after heating, with uniform color blocks and a gradual fading of color from the center to the periphery.
