Will the tag coated paper fade after long-term storage?

After long-term storage, the tag coated paper may fade, but the degree and speed of fading will be affected by a variety of factors.

First, the characteristics of coated paper itself

Coated paper, also known as printing coated paper, has the characteristics of whiteness and gloss are very good, which makes it in printing or printing can make the picture and picture reflect the three-dimensional sense. However, coated paper is not inherently waterproof, and the coating on its surface can be affected after encountering a wet environment, causing the silty to peel off or fade in color. Therefore, the coated paper tag stored in a humid environment for a long time is more likely to fade.

Second, ink performance and technology

1.Ink performance: The fading and discoloration of printed products are closely related to ink performance. Factors such as light resistance, weather resistance and chemical resistance of the ink will affect the long-term stability of the printed matter. If the ink quality is poor or the formula is not suitable for coated paper, then the image and text printed on coated paper are more likely to fade after long-term storage.

2.Printing process: Some factors in the printing process, such as the acid and alkali of the wetting fluid, drying temperature, etc., may also affect the adhesion and stability of the ink, which will affect the long-term preservation effect of the print.

Third, Storage environment and conditions

1.IlluminationExposure to strong sunlight for a long time, ultraviolet rays will accelerate the decomposition of pigments in the ink and the aging of the paper, resulting in the fading of the coated paper tag.

2.Temperature and humidity: the high temperature and humidity environment will accelerate the aging of paper fibers and the oxidation of ink, thereby shortening the storage life of coated paper tags. On the contrary, a dry and low temperature environment helps to extend the shelf life of printed matter.

3.Air pollutants: acid and alkali gases in the air, oxidizing gases, etc., will also have an adverse effect on coated paper tags, accelerating their fading and aging.

Fourth, Other factors

In addition to the above factors, the chemicals in the paper, additives in the production process, etc., may also have an impact on the long-term stability of the coated paper tag. For example, dark substances such as lignin in paper may gradually appear after prolonged exposure, causing the paper to turn yellow or affecting the color effect of the print.

Fifth, Conclusions and Suggestions

In summary, the long-term storage of the tag coated paper may fade, but the degree and speed of fading is affected by a variety of factors. In order to extend the shelf life of coated paper tags and maintain their color freshness, it is recommended to take the following measures:

1.Select high quality ink and suitable printing process;

2.Avoid prolonged exposure to strong sunlight and humidity;

3.Control the temperature, humidity and air quality of the storage environment;

4.Check and maintain the status of coated paper tags regularly.
