Can the long-term thermal paper pos machine be used
The appearance of long-lasting thermal paper has reassured many people who use it, because its long-term storage time perfectly complements the shortcomings of ordinary thermal paper, but some people ask, long-lasting thermal paper pos machine can use?
Long-lasting thermal paper can be stored for 5 years after printing (under the conditions of room temperature and avoid direct sunlight), and long-lasting thermal paper can be stored for 10 years, but if the formula of thermal coating is unreasonable, it may only be Save for a few months. The protective coating is also critical to the shelf life after printing, it absorbs some of the light that causes the heat-sensitive coating to react chemically, slowing down the deterioration of the printing paper.
Pos paper roll, also known as thermal fax paper, thermal recording paper, thermal copy paper, is a communication carrier for fax machines and pos machines to transmit text and graphics, that is, fax paper, receipts.
Ordinary pos thermal paper is not suitable for long-term storage, but good thermal paper can be stored for 30 years or more. There are three ways to identify the quality of thermal paper:
1. Appearance: If the paper is very white, it means that the protective coating and thermal coating of the paper are unreasonable, and too much phosphor is added, and the better paper should be slightly greenish. If the paper has a low finish or looks uneven, it means that the coating of the paper is uneven. If the thermal paper is very reflective, it means that too much phosphor is added, which will also reduce the quality of the thermal paper.
2. Fire roasting: Use a lighter to heat the back of the paper. If the color on the paper is brown, it means that the thermal formula is not reasonable, and the storage time may be relatively short. If the black part of the paper has small stripes or color blocks Uneven, indicating that the coating is uneven. Better quality paper should be dark-green when heated, with uniform patches of color, gradually fading from the center to the periphery.
3.Comparison and identification of sunlight exposure: Apply the printed paper with a highlighter and place it in the sun to accelerate the reaction of the thermal coating to light. The faster the paper turns black, the shorter the shelf life of the paper.
