What are the general specifications of thermal printing paper?
Thermal printing paper has now been widely used in various industries. High-quality thermal printing paper has uniform color, good gloss, high whiteness, and a small amount of green. If the thermal printing paper seems to reflect light strongly, it is likely that too much fluorescent pigment has been added. If the black part of the thermal printing paper has fine streaks or uneven color blocks, it indicates that the coating is uneven. So, what are the general specifications of thermal printing paper?
The most common ones are 80mm×Φ60mm and 57mm×Φ50mm.
Thermal printing 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 is generally 1 or 2mm, it has no effect on the use, because the printer 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 roll is directly related to the cost-effectiveness of this roll of paper, if the diameter is 60mm, but the actual diameter 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 printing paper rolls sold on the market are generally marked with X0, and the actual diameter is often less than X0.
The commonly used specifications and models of thermal printing paper are as follows: 57x50, 57x60, 57x80, 75x50, 75x60, 75x80, 80x50, 80x60, 80x80, 80x140, etc.
At the same time, we need to pay attention to the diameter of the tube core in the middle of a roll of paper. Some businesses will also make manipulations on the tube core, and choose a larger tube core, and the length of the paper will be much shorter. The simple way is that the purchaser can bring a small ruler to measure whether the diameter is consistent with the diameter marked on the packaging box. The diameter of the tube core also needs to be paid attention to, so as not to be deceived by the unscrupulous merchants.
