What should I do if the coating on the wax based carbon ribbon falls off during the printing process?

Coating detachment of wax based carbon ribbon during printing is a common issue that may be caused by various factors. Here are some solutions to this problem:

1、 Analyze the reasons

Improper printing conditions:

Low printing temperature: may result in insufficient adhesion between the carbon ribbon and the paper.

Excessive printing pressure: It may also affect the bonding effect between carbon ribbon and paper.

Poor storage environment:

High temperature environment: may cause the wax based carbon ribbon to soften and the coating to easily peel off.

High humidity environment: may cause moisture to the carbon ribbon coating, affecting the printing effect.

Direct sunlight: Prolonged exposure may cause oxidation and deterioration of the carbon ribbon coating.

Carbon ribbon quality issues:

Poor quality carbon ribbon: may use low-quality wax or ink, which is prone to detachment during the printing process.

Unreasonable formula: Poor adhesion and stability of the pigment, affecting the printing effect.

Printer or ribbon installation issues:

Printer thermal head aging or damage: may result in poor printing performance.

Incorrect installation method of carbon ribbon: If the tension is uneven, it may cause the coating to peel off during the printing process.

2、 Solutions

Choose high-quality carbon ribbon:

Choose well-known brands and channels when purchasing to ensure reliable quality of carbon ribbon.

High quality carbon ribbon uses high-quality wax and ink, with strong coating adhesion and not easy to peel off.

Reasonably adjust printing parameters:

Adjust parameters such as printing temperature, speed, and pressure according to actual needs.

Appropriate printing parameters can ensure the adhesion between carbon tape and paper, reducing coating peeling.

Properly store carbon ribbon:

Store the carbon ribbon in a cool, dry, and dark place.

Avoid prolonged exposure to high temperatures, high humidity, or direct sunlight.

Check and maintain the printer:

Regularly check the thermal head and other components of the printer to ensure their proper functioning.

If the thermal head is found to be aged or damaged, it should be replaced in a timely manner.

Correctly install carbon ribbon:

Install the carbon ribbon correctly according to the instructions.

Ensure even tension of the carbon ribbon and avoid situations where it is too loose or too tight.

3、 Consideration of special application scenarios

For some special application scenarios, such as labels that require long-term storage or outdoor use, better weather resistant carbon tape or special printing processes can be considered to improve the durability of the labels.

In summary, solving the problem of coating peeling off during the printing process of wax based carbon ribbons requires starting from multiple aspects, including selecting high-quality carbon ribbons, adjusting printing parameters reasonably, storing carbon ribbons properly, inspecting and maintaining printers, and installing carbon ribbons correctly. At the same time, corresponding measures can also be taken to improve the persistence of labels for special application scenarios.
