What is the principle of mixed base carbon strip printing?

The principle of mixed base carbon strip printing is mainly based on heat transfer technology. Specifically, its printing process can be summarized as the following steps:

1. Carbon tape and medium through the print head

In a thermal transfer printer, the mixed base carbon strip passes through the print head along with the medium that needs to be printed (such as label paper, plastic labels, etc.). Inside the printhead is a series of ceramic heating elements that control the temperature very precisely.

2. Heat the carbon strip to melt the toner

When the print head receives a print command, the ceramic heating element quickly heats up to a preset temperature. As the mixed base carbon strip passes through the heated zone, the toner layer on it is heated and melted. The mixed base carbon strip adds more resin components on the basis of the wax base, so it has a high melting point and excellent scratch resistance and chemical resistance.

3. Toner transfer under pressure

At the same time as the toner melts, the printer applies a certain pressure to transfer the melted toner from the surface of the carbon strip to the medium. This process requires very precise control of temperature, pressure and speed to ensure that the toner can be uniformly and clearly transferred to the medium to form the desired graphic information.

4. Cooling and curing to form a printing effect

After completing the toner transfer, the toner on the medium gradually cools and solidifies, creating a long-lasting and clear print effect. The graphic information printed by the mixed base carbon tape has excellent properties such as high temperature resistance, stain resistance, friction resistance and corrosion resistance, which can meet the needs of various application scenarios.

To sum up, the principle of mixed-base carbon strip printing is to melt the toner of the carbon strip and transfer it to the medium through the heat transfer technology, and then to form a lasting and clear printing effect through cooling and curing. This process requires precise control of several parameters such as temperature, pressure and speed to ensure print quality.
