The thermal cash register rolls are divided into three layers according to the chemical properties of each layer of paper. The bottom layer is the paper base. After some surface treatment of ordinary paper, it can be used for the attachment of heat sensitive substances. The second layer is the thermal coating. This layer is the aggregate of various chemicals, which are coloured after being heated. The third layer is the protective layer, which protects the text or pattern from being damaged by the outside world.
Thermal layer is mainly composed of three chemical components, colorless dyes, color reagents and adhesives. At normal room temperature, these three components will not undergo chemical reactions, but when the thermal paper meets the heated printing head, the colorless dyes will react with the developer, and then present the information we see in the text and so on.
These text messages will appear black, blue, purple and other colors according to the different colorless dyes selected. This is why we may receive different font color tickets in different occasions.
