Thermal paper is a processed paper product manufactured by coating a layer of “heat-sensitive coating” (heat-sensitive color-changing layer) on high-quality base paper. It has certain thermal induction characteristics and is widely used in supermarkets, banks, etc. , logistics and other application scenarios to improve printing efficiency and ensure printing quality.
Thermal paper is mainly composed of paper base, thermal coating and protective layer. Thermal paper is mainly used in supermarkets, banks, logistics and other fields or scenarios. The use of thermal paper in the supermarket scene can prevent the color from being unclear, the use of the bank scene can prevent the printing from being too slow, and the logistics scene can prevent the color fading caused by long-term storage.
Thermal paper is generally sold in the form of rolls, generally 80mm×Φ60mm, 57mm×Φ50mm and other specifications are the most common, the front number indicates the width of the paper roll, and the back is the diameter. If the width generally has an error of 1 or 2mm, it will not affect the use, because Printers generally cannot print on the edge, but the diameter of the paper roll has a greater impact on the purchaser, because the total length of the paper rolled by the paper roll is directly related to the cost performance of the roll of paper. If the diameter is 60mm, but the actual If it is only 58mm, the length of a roll of paper will be reduced by about 1 meter (the specific reduction depends on the thickness of the paper), but the thermal paper rolls sold on the market are generally marked with X0, and the actual diameter is often less than X0. There is another thing that we need to pay attention to is the diameter of the die in the middle of a roll of paper, some merchants will play a trick on the die, they will choose bigger die, the length of the paper will be shortened a lot. The simple way is that the purchaser can take a small ruler to measure whether the diameter is consistent with the diameter marked on the packaging box. The diameter of the die also needs to be paid attention to, so as not to cause the purchaser to suffer a loss due to unscrupulous merchants.
