The back coating of the all-resin carbon strip plays a crucial role in the printing process. The following are the main functions of the back coating:


1. Protect the print head

Reduce wear: The back coating is located on the side of the carbon strip in contact with the print head, and its main function is to prevent direct contact between the carbon strip and the print head, thereby reducing the wear of the print head during the long printing process. This helps extend the life of the print head and reduce maintenance and replacement costs.

Prevent print residue: During the printing process, the contact between the carbon strip and the print head can create mechanical friction, which may lead to residual toner, ink and other impurities on the print head. The back coating can effectively prevent the transfer of these residues to the printing medium, keeping the print head clean, thus ensuring print quality.

2. Enhance heat transfer

Optimize the printing effect: The printing method of thermal transfer relies on the heat energy released by the print head to transfer the ink on the carbon strip to the printing medium. The back coating helps dissipate electrostatic charges and prevent static buildup, thereby effectively regulating and optimizing the heat transfer process. This helps to avoid heat waste or uneven ink printing, improving print quality and efficiency.

3. Improve the stability of carbon belt

Protection against environmental factors: The back coating provides additional protection to the carbon strip, allowing it to resist the intrusion of moisture, dust and other particles. These environmental factors can negatively affect the quality and performance of the carbon strip, and the back coating helps maintain the stability and durability of the carbon strip.

Keep flat and undeformed: The back coating can also enhance the structural stability of the carbon strip and help the carbon strip remain flat and undeformed during the printing process. This helps the ink to remain evenly distributed throughout the printing process, further improving print quality.


In summary, the back coating of the all-resin carbon strip plays an important role in protecting the print head, enhancing heat conduction and improving the stability of the carbon strip. Together, these features ensure high-quality printing results and extend the life of the printing equipment and the carbon strip. Therefore, when selecting the carbon strip, the performance and quality of its back coating should be paid attention to.
