White printed Five proof receipt paper Five proof ATM machine printing paper The working principle of thermal printing labels is mainly based on the special chemical properties of thermal paper and the working mechanism of thermal printers
Five proof receipt paper Five proof ATM machine printing paper White printed The structure and characteristics of thermal paper
White printed Thermal paper is the core part of thermal printing labels and is generally composed of three layers. The bottom layer is the paper base, which provides support; the middle layer is the thermal coating, which is the key part of printing and is mainly composed of chemical substances such as thermal colorants and developers; the top layer is a protective layer, which is used to protect the thermal coating and prevent it from being affected by the external environment. White printed The thermal colorants and developers in the thermal coating are in a stable state at room temperature, isolated from each other, and will not react chemically. However, when the thermal coating is subjected to a certain temperature, the thermal colorants and developers will react chemically, resulting in color changes, forming visible text, images or barcodes and other information.
Five proof receipt paper White printed The working process of thermal printers
White printed White printed Data transmission: When a thermal label needs to be printed, the computer or other device will transmit the content to be printed to the thermal printer in the form of digital signals. These digital signals contain the encoding of various information such as text, images, barcodes, etc.
Five proof ATM machine printing paper Five proof receipt paper Print head heating: There is a print head inside the thermal printer, which is composed of many tiny heating elements. After receiving the data signal, the printer's control circuit controls the various heating elements on the print head to heat in a specific order and time according to the data content.
Five proof receipt paper TWhite printed hermal reaction: The thermal paper passes under the print head.White printed When the heating element is heated to a certain temperature, the chemical substances in the thermal coating of the thermal paper in contact with the heating element react to change the color of the coating at the corresponding position. By controlling the heating time and temperature of the heating element, the degree of color change can be controlled, thereby achieving the printing of text and images of different shades and shapes.
Five proof receipt paper White printed Complete printing: As the thermal paper continues to move, the print head continues to heat, and all the information in the data signal is printed on the thermal paper in sequence, finally forming a complete thermal print label.
