How to avoid the color fading of the printed content of thermal label paper?

To avoid the color fading of the printed content of thermal label paper, you can start from the following aspects:

First, choose the appropriate thermal label paper

1.Paper quality: Choosing heat-sensitive label paper with good paper quality and durability can significantly reduce the possibility of fading. Good thermal paper can last longer, some can even reach 30 years or more.

2.Special coating: Consider using thermal paper with waterproof, oil-proof, scratch-proof and other characteristics, such as true three-proof paper, which can also keep the printed content clear in harsh environments.

Second, the correct printing and storage methods

1.Avoid high temperature and direct sunlight: Writing on thermal paper tends to fade in high temperature and direct sunlight. Therefore, the printed heat-sensitive label paper should be placed in a cool place away from light and away from heat sources.

2.Humidity control: Keep the environment dry to avoid excessive humidity resulting in moisture on the paper, which will affect the clarity of the printed content.

3.Avoid chemical contact: Thermal paper should avoid direct contact with chemicals, because some chemicals may destroy the coating on the surface of the paper, causing the printing content to fade.

Third, proper packaging and storage

1.Use a transparent plastic bag or folder: The printed heat-sensitive label paper is sealed in a transparent plastic bag or folder, which can effectively prevent the intrusion of dust and other pollutants.

2.Layering: The printed thermal labels should be stacked in layers to prevent glue penetration and adhesion, which may affect storage effect.

3.Sealed packaging: After each use, the remaining heat-sensitive label paper should be resealed and packaged to maintain its good preservation state.

Fourth, regular inspection and maintenance

1.Check the printing equipment: Check and clean the printing equipment regularly to ensure its cleanliness and normal operation, to avoid the deterioration of print quality caused by equipment problems.

2.Pay attention to the quality of the paper: During the printing process, pay attention to the quality change of the thermal label paper. If the printing is not clear or the color is uneven, replace the paper or check the device in time.

Fifth, other precautions

1.Avoid glue paste: For non-adhesive printer paper, avoid using glue or transparent adhesive paste methods, as these methods may accelerate the disappearance of the writing.

2.Choose the right printer: If you need to store labels or documents for a long time, consider using a thermal transfer label machine/printer or inkjet, laser printer, etc., which is more durable.

In summary, to avoid the fading of the printed content of thermal label paper, it is necessary to select the appropriate paper, correct printing and storage methods, proper packaging and storage, regular inspection and maintenance, and pay attention to other related matters. By taking these measures, the storage time of thermal label paper can be extended to ensure the clarity and readability of the printed content.
