For many customers, identifying the quality of thermal paper may only focus on the price and feel of the paper, and do not know how to correctly identify the thermal paper. Today, I will popularize the method for identifying thermal paper and how to identify it. What is the quality of the thermal paper you use?

  First from the appearance, ifthe paper is very white, it means the paper The protective coating and thermal coating are unreasonable, and too much phosphor is added. Really good quality thermal paper should be slightly greenish. If the paper is not smooth or looks uneven, it means that the thermal paper coating is not uniform. If the thermal paper seems to reflect strong light, too much phosphor has been added, and the quality is not good, and paper scraps will appear. Excessive and excessive dust.

  Second, you can use fire roasting method. The method of roasting with fire is also very simple. Use a lighter to heat the back of the paper. If the color that appears on the paper is brown after heating, it means that the heat-sensitive formula is not Too reasonable, the storage time may be relatively short, if the paper appears black, and there are some small streaks or uneven color blocks, it means that the coating is uneven. The paper of better quality should be black and green (with a little green) after heating, and the color block should be uniform, and the color gradually fades from the center to the periphery. This kind of thermal paper has good color development and long storage time.

   Third, you can use the method of sunlight contrast identification: smear the printed paper with a highlighter and put it in the sun (this can accelerate the reaction of the thermal coating to light), which paper The fastest it turns black, the shorter the storage time.

  So when you buy thermal paper, you need to see the value of thermal paper instead of price.
