How to prevent the contents of thermal label paper from fading after printing on small rolls?

To prevent the contents of the small roll of thermal label paper from fading after printing, you can start from the following aspects:

First, choose high quality thermal label paper

1.Look at brands and word-of-mouth: Choose brands with good word-of-mouth and reputation, which are usually more focused on product quality and stability.

2.Check the quality of the paper: ensure that the paper has a high whiteness, uniform paper quality and high heat resistance. High quality thermal label paper has clearer color and slower fading under the same conditions.

Second, the correct use and storage of heat-sensitive label paper

1.Keep the label dry and clean: Avoid placing the label in a place that is damp or in direct sunlight. Moisture will accelerate the fading of the paper, and direct sunlight will make the paper yellow and brittle. At the same time, be careful not to wipe or smear the surface of the label paper forcefully during use to prevent wear and fading.

2.Storage away from light: Place the printed paper in a place away from light and avoid direct sunlight, because ultraviolet rays in sunlight will accelerate the fading of the paper. Keep the paper properly stored in a dry and clean environment, maintain a stable temperature and humidity, and avoid excessive or low temperature and humidity to cause damage to the paper.

3.Physical isolation: You can consider using a transparent plastic bag or folder to wrap the printed paper to avoid contact with dust or other contaminants to provide some protection.

Third, control the appropriate printing temperature

1.Reasonable setting of printing temperature: the thermal label paper needs to generate a certain temperature through the thermal printer to make the thermal layer on the paper color reaction, so as to form the printed content. However, too high a printing temperature will cause the paper to locally turn yellow or black, while too low a printing temperature will cause the printing content to be unclear and easy to fade. Therefore, the printing temperature should be correctly set according to the requirements of the specific thermal label paper and printing equipment during use to avoid too high or too low printing temperature.

Fourth, reasonable design of label content and printing layout

1.Stable color selection: When designing the label content, you should choose some ink with a more stable color to print the label content, and avoid using too much color to reduce the risk of fading.

2.Optimize the layout: In the layout should try to avoid dense content or typesetting confusion, so as not to cause the local temperature of the paper is too high and damaged.

Fifth, regular maintenance of printing equipment

1.Clean the print head: The print head is the core part of the thermal printer, and its state directly affects the print quality. Regular inspection of print head wear and cleaning can ensure good contact between print head and paper and reduce the occurrence of fading.

In summary, to prevent the fading of the printed contents of small roll thermal label paper, it is necessary to select high-quality thermal label paper, correctly use and store thermal label paper, control the appropriate printing temperature, rationally design label content and printing layout, and regularly maintain printing equipment. Through the implementation of these measures, the storage period of the printed content of thermal label paper can be effectively extended.
