What is the production process of TTO high-speed coding carbon tape?

The production process of TTO high-speed coding carbon tape mainly includes the following steps:

1、 Prepare the basement film

Firstly, it is necessary to prepare high-quality base film, usually using polyester (PET) film. This material has excellent mechanical strength and thermal stability, capable of withstanding the heat and pressure during the printing process while ensuring the clarity and durability of printed information.

2、 Coating ink layer

Coating ink layer on the base film is one of the key steps in producing TTO high-speed coding carbon tape. The ink layer is usually composed of resin based, mixed based, or wax based inks, which soften and transfer to the surface to be printed when heated. The application of ink layer needs to be carried out in a well controlled environment to ensure that the ink layer is uniform and consistent. The coating process may involve multiple techniques, such as screen printing and gravure coating, depending on the required ink layer thickness and uniformity.

3、 Coating release agent layer

The release agent layer is usually coated on the back of the ink layer to prevent ink from sticking to the print head during the printing process. The selection and coating quality of the release agent layer are crucial for the protection of the print head and the stability of print quality. The coating of release agent layer also needs to be carried out in a well controlled environment to ensure its uniformity and adhesion.

4、 Apply back coating

The back coating is another important component of TTO high-speed coding ribbon, which mainly serves to lubricate the print head, protect the print head, and prevent static electricity accumulation. The back coating is usually composed of special lubricants, anti-static agents, and other materials. When applying the back coating, it is necessary to ensure that the coating is evenly and firmly attached to the base film.

5、 Drying and curing

After coating each layer, the carbon ribbon needs to be dried and cured. The purpose of this step is to remove the solvent and solidify the ink layer, release agent layer, and back coating to ensure their stability and adhesion. The drying and curing process needs to be carried out under appropriate temperature and humidity conditions to avoid adverse effects on the performance of the carbon ribbon.

6、 Cutting and rolling

Finally, cut the dried and cured carbon ribbon into appropriate widths and roll it onto a drum. The purpose of this step is to meet the needs of different models of printers and ensure that the ribbon can be smoothly conveyed and printed during use.

In summary, the production process of TTO high-speed coding carbon tape includes steps such as preparing the base film, coating the ink layer, coating the release agent layer, coating the back coating, drying and curing, as well as cutting and rolling. The precise control and optimization of these steps are crucial for ensuring the printing effect, adhesion, and wear resistance of carbon ribbons.
