The notepaper that tearing out from a small printer machine is thermal paper or heat-sensitive paper. It is used in small print machines and fax machines.
Thermal printing paper is generally divided into three layers: paper base, thermal coating, protective layer. However, thermal coating and protective layer have a great impact on the final effect. The more uniform the thermal coating, the more uniform the color printed out, the better the visual effect. If the thermal coating is not uniform, it will lead to different colors and lower print quality. Whether the chemical formula of thermosensitive coating is reasonable or not directly affects the preservation time of printing paper.
