Method for identifying thermal cash register paper

The thermal cash register paper is a roll paper produced by simple processing using thermal paper as a raw material. Also known as: roll-type thermal cash register paper, thermal printing paper. The thermal cash register paper is mainly used in the thermal printer of the cash register system. The thermal cash register paper has uniform color, good smoothness, high whiteness, long storage period, no need to print consumables, no ribbon, ribbon or ink cartridge. Therefore, in the cash register system, the thermal cash register paper has a tendency to replace the ordinary cash register paper. Thermal cash register paper is now widely used in supermarkets, hotels, banks, telecommunications, medical and other industries.
The cash register paper thermal printing paper is generally divided into three layers, the bottom layer is paper base, the second layer is heat sensitive coating, the third layer is protective layer, and the heat sensitive coating is a special capsule, which is exposed to heat. . The main effect of its quality is the heat-sensitive coating or protective layer.
Paper thermal paper features, purchase method:

Thermal paper is specially used for printing on thermal printers and thermal fax machines. The quality of the paper is directly affected by the quality of the print and the storage time, and even affects the service life of the printer and fax machine. At present, the thermal paper on the market is not uniform, and the country has not yet issued a national standard. Many users are not sure how to identify the quality of thermal paper. This provides convenience for many merchants to keep inferior thermal paper, causing losses to users. The storage time is shortened, the writing is blurred, and the printer is damaged. The top electronics here tell you how to identify the pros and cons of thermal paper so as not to be fooled again.

The cash register paper thermal printing paper of the cash register is generally divided into three layers, the bottom layer is paper base, the second layer is heat-sensitive coating, and the third layer is protective layer, which mainly affects the quality of the heat-sensitive coating or protective layer. If the coating of the thermal paper is uneven, it will cause darkness in some places, light color in some places, and print quality will be significantly reduced. If the chemical formula of the thermal coating is unreasonable, it will cause the paper to be stored. It has become very short. Good printing paper can be saved after printing (at normal temperature and avoiding direct sunlight) for 5 years. Now there are more long-lasting thermal papers that can be stored for 10 years, but if the formula of heat-sensitive coating is unreasonable, it may only be Save for a few months. The cash register paper protective coating on the cash register of the mall is also critical for the storage time after printing. It absorbs some of the light that causes the thermosensitive coating to react chemically, slows down the deterioration of the paper, and protects the thermal element of the printer from damage, but if the protective coating is not uniform, it will not only greatly reduce the thermal coating. The ground protection, even during the printing process, the fine particles of the protective coating fall off, rubbing the thermal element of the printer, causing damage to the printed thermal element.
Thermal paper quality identification

1. Appearance: If the paper is very white, it means that the protective coating and heat-sensitive coating of the paper are unreasonable, and too much phosphor is added. The better paper should be slightly greenish. The paper finish is not high or looks uneven, indicating that the paper coating is uneven. If the paper looks very reflective, it adds too much phosphor and the quality is not good.
2, fire roast: the method of roasting with fire is also very simple, use a lighter to heat the back of the paper, if heated, the color on the paper is brown, indicating that the thermal formula is not reasonable, the storage time may be shorter, if The black part of the paper has small streaks or uneven color patches, indicating uneven coating. The paper of better quality is black green (with a little green) after heating, and the color is even, and the color gradually fades from the center to the periphery.
3, sunlight exposure contrast identification: the printed paper is painted with a highlighter and placed in the sun under the sun (this can accelerate the thermal coating response to light), which paper is the fastest black, indicating the more time can be saved short.
