In all major supermarkets, they are indispensable. To buy a good thermal cash register paper brand, we must first learn how to judge the quality of thermal cash register paper.
Thermal cash register paper is used in thermal printers. The principle of thermal paper is to apply a layer of “heat-sensitive paint†(thermographic color-changing layer) on the base paper. The thermal head of the thermal printer is equipped with a semiconductor heating element. The print head can be printed after heating and contacting the thermal printing paper. The pattern you need. The thermal paper has the side of the paint that is opposite the print head. In the process of use, pay attention to the direction of the paper can not be reversed. So how to choose a good thermal cash register paper brand, how to judge their quality is good or bad? Mainly divided into the following steps:
1. Identification of sunlight exposure:
Apply the highlighter to the printed paper and place it in the sun (this will speed up the thermal coating's response to light), which paper will turn darker the fastest, indicating the shorter the time to save.
2, paper appearance:
Some papers look very white, indicating that the paper's protective coating and heat-sensitive coating are unreasonable, adding too much phosphor, and the better paper should be slightly greenish. Paper finish is not high or looks uneven, indicating uneven paper coating. If the paper looks very reflective, it is not ideal because it adds too much phosphor.
3, fire roast identification:
This method is very simple. 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. If the black part of the paper is small, Uneven stripes or color blocks indicate uneven coating. Paper of better quality should be black-green (with a little green) after heating, and the color blocks are even, and the surrounding colors gradually fade to expand outward from the center.
At present, the well-known thermal cash register paper brands are:
