Can the heat-sensitive label paper be reused?

Three heat-proof label paper generally can not be reused. This is mainly because of its working principle and material characteristics.

Working principle

The surface of the heat-resistant label paper is coated with a special heat-sensitive coating, which reacts with the chemical substances in the coating when subjected to the heat of the heat-sensitive print head, thereby displaying the required text and images. This color development process is irreversible, that is, once the thermal paper is heated to develop color, it can not be restored by heating.

Material characteristics

1.Stability: Although the three thermal label paper is more stable than ordinary thermal paper, with waterproof, oil and alcohol (or scratch) resistant characteristics, but these characteristics are mainly to protect the printed content in a specific environment from being destroyed, rather than support reuse.

2.Durability: After special treatment, the heat-sensitive label paper can resist the influence of the external environment to a certain extent, but its heat-sensitive coating will still have a chemical reaction after heating, resulting in color change, which is irreversible.

Effects of reuse

Print quality: The repeated use of three heat-resistant label paper can not obtain satisfactory printing results, because the heat-sensitive coating has undergone chemical reactions, reheating may not be uniform color, or even blurred.

Equipment damage: Every time you print, the printer will heat the paper, and the heat-sensitive coating may deteriorate after several times of heat, resulting in blockage or wear of the print head, which affects the normal operation of the printer.

Environmental and cost considerations

From an environmental point of view, the reuse of thermal paper is not wise. With the increase of printing times, the text and images on the thermal paper will gradually blur and cannot be clearly displayed, which not only affects the transmission effect of information, but also may cause unnecessary waste. At the same time, considering the relatively high cost of heat-sensitive label paper, repeated use does not bring significant cost savings.

In summary, the three heat sensitive label paper generally can not be reused. In order to ensure the printing quality and accuracy of information transmission, as well as to protect the printer equipment and save resources, it is recommended to follow the principle of one-time use when using the three heat-resistant label paper.
