Identification method of heat-sensitive cashier paper: first look at the appearance of the paper, good quality of heat-sensitive cashier paper with uniform hair color, good smoothness, high whiteness, a little greenish. If the paper is very white, the paper protective coating and thermal coating is unreasonable, adding too much phosphor, if the paper is not smooth or looks uneven.

Then the paper coating is not uniform, if the paper looks very reflective light, but also added too much phosphor. Secondly, the paper is baked by fire and heated by fire on the back of the paper. If the color on the paper is brown, the heat-sensitive formula is not reasonable and the storage time may be shorter.
