It's only a Trick to Distinguish the Good from the Bad of the Thermal Cash Register Rolls

1. Pay more attention to the appearance of paper when purchasing thermal cash register rolls. From the color, we can distinguish the quality of the protective coating and the thermal sensitive coating to a certain extent. If the paper is very white, it shows that the protective coating and thermal coating of the paper are unreasonable, and it is likely to add too much phosphor. If the paper is slightly greenish, its quality should be better. If the paper looks smooth and flat, the coating of the thermal paper is more uniform. On the contrary, the uneven coating of the paper will seriously affect the printing effect. At the same time, if the paper looks very reflective, but also because of the addition of too much phosphor, it is best not to choose such a thermal paper.

2. Contrastive identification of sunshine exposure: This method is very simple, just use the same fluorescent pen to smear different printed papers and put them in the sun (which can accelerate the reaction of thermal coatings to light). Eventually, they will become dark. The longer the time required for blackening, the longer the paper in this thermal cash register rolls will be preserved.

3. Barbecue: In fact, the method of barbecue and sunshine to identify, its principle is similar. You can use a lighter to heat the back of the paper slowly, and the color of the paper will change with the heating. If the final color is brown, it means that the heat-sensitive formula is not reasonable and the storage time may be shorter. If there are small stripes or dispersed color blocks on the paper, it means that the coating is not uniform. On the contrary, the heat-sensitive paper with better quality will eventually appear black-green (with a little green) after heating, and the color block is uniform. The color gradually fades from the center of heating to the surrounding area.
