How to maintain the color brightness of colored thermal sensitive synthetic paper?

To maintain the color brightness of colored thermal sensitive synthetic paper, it is necessary to start from multiple aspects. Here are some effective methods:

1、 Choose the appropriate paper

High quality materials: Choose colored thermal sensitive synthetic paper using high-quality BOPP film as the substrate. This material has better physical and thermal properties, allowing it to maintain bright colors for a longer period of time.

Special coating: Choose thermal paper with waterproof, oil resistant, scratch resistant and other properties that help protect printed content from external environmental damage, thereby maintaining the brightness of colors.

2、 Correct printing settings

Suitable printer: Choose a printer suitable for color thermal synthetic paper and ensure that it has good printing quality and stability.

Printing parameter adjustment: Adjust printing temperature, speed, pressure, and other parameters based on the characteristics of the paper and the performance of the printer to achieve the best printing effect.

3、 Reasonable storage conditions

Avoid high temperature and direct sunlight: High temperature and direct sunlight can accelerate the reaction of chemicals in the thermosensitive coating, making the color unstable or even fading. Therefore, the printed color thermal sensitive synthetic paper should be placed in a cool and dark place.

Control humidity: Keep the environment dry and avoid excessive humidity that can cause paper to become damp. A humid environment may accelerate the process of color change, affecting the vividness of colors.

Avoid contact with chemicals: Some chemicals may damage the coating on the surface of the paper, causing the printed content to fade. Therefore, direct contact between thermal paper and these chemicals should be avoided.

4、 Adopt protective measures

Transparent plastic bag or folder sealing: Seal and package the printed color thermosensitive synthetic paper in a transparent plastic bag or folder to effectively prevent dust and other pollutants from entering, thus protecting the brightness of the color.

Use protectants: There are some protectants on the market specifically designed to protect the color of thermal paper, which can be applied to the surface of the paper to form a protective film and extend the color retention time. But please ensure compatibility between the protective agent and the paper before use.

5、 Regular inspection and maintenance

Check printing equipment: Regularly inspect and clean printing equipment to ensure its cleanliness and normal operation. To avoid a decrease in print quality caused by equipment issues, which can affect the brightness of colors.

Observing paper quality: During storage and use, pay attention to observing the quality changes of colored thermosensitive synthetic paper. If uneven color or fading is found, timely measures should be taken to deal with it.

In summary, maintaining the color brightness of colored thermal sensitive synthetic paper requires starting from multiple aspects such as selecting suitable paper, correct printing settings, reasonable storage conditions, adopting protective measures, and regular inspection and maintenance. By taking these measures, the service life of colored thermosensitive synthetic paper can be extended while maintaining its vibrant color and readability.
