How to choose a good thermal cash register paper?Update: 2022-12-20

1. Observation: When purchasing thermal paper, pay more attention to the appearance of the paper. From the color, we can distinguish the quality of its protective coating and thermal sensitive coating. If the paper is very white, it indicates that the protective coating and thermal sensitive coating of the paper are unreasonable, and it is likely that too much phosphor has been added. If the paper is slightly green, its quality should be better. If the paper looks smooth and flat, the coating of thermal paper is more uniform. Otherwise, it indicates that the paper coating is uneven, which will seriously affect the printing effect. At the same time, if the paper seems to reflect light very strongly, it is also the reason that too much phosphor is added. It is recommended not to choose such a thermal paper.

 

2. Comparison and identification of sunlight: This method is very simple. Just smear different printed papers with the same fluorescent pen and place them in the sun (this can accelerate the reaction of the thermal sensitive coating to light). They will all turn black. The longer it takes to turn black, the longer this thermal paper will be kept.

 

3. Fire baking: In fact, the method of fire baking is similar to that of sunlight. You can use a lighter to slowly heat the back of the paper. The color of the paper will change with the heating. If the color is brown, it indicates that the thermal formula is not reasonable and the storage time may be short; If fine stripes or scattered color blocks are visible on the paper, it indicates that the coating is uneven. On the contrary, the heat sensitive paper with good quality will appear dark green (with a little green) after heating, and the color blocks will be uniform. The color will gradually fade from the heating center to the surrounding.
