What is the color stability of the hanging tag copperplate paper? Will it fade?

The color stability of hanging tag copperplate paper is relatively good, but fading may still occur under specific conditions. The following is a detailed analysis of the color stability of hang tag copperplate paper:

1、 Overview of Color Stability

The color stability of hang tag copperplate paper mainly depends on its paper quality and ink quality. High quality copperplate paper and high-quality ink can ensure that printed patterns and text have bright and long-lasting colors that are not easily faded. In addition, printing and post-processing techniques can also affect the color stability of hang tag copperplate paper.

2、 Factors affecting color stability

Light exposure: Prolonged exposure to strong sunlight may cause the printed color on the copper plate paper of the hang tag to gradually fade. This is because ultraviolet radiation can damage the pigment molecules in the ink, causing the color to become lighter.

Dampness: If the hanging tag copperplate paper is exposed to a humid environment for a long time, the ink may expand and fall off due to water absorption, thereby affecting the stability of the color.

Chemical substances: Certain chemical substances, such as acids, bases, oxidants, etc., may react with ink, causing color changes or fading.

Physical friction: Long term physical friction may also cause ink layer wear, thereby affecting the durability of color.

3、 Methods to improve color stability

Selecting high-quality materials: Choosing high-quality copperplate paper and ink is the foundation for ensuring color stability. These materials usually have better properties such as light resistance, moisture resistance, and chemical corrosion resistance.

Optimizing printing process: Reasonable printing process parameters, such as ink viscosity, printing pressure, drying temperature, etc., also have a significant impact on color stability. By optimizing these parameters, the adhesion and color saturation of ink can be improved.

Post processing technology: The printed hang tag copperplate paper is subjected to post-processing techniques such as film coating and polishing, which can form a protective film to prevent direct contact between ink and the external environment, thereby improving color stability.

4、 Prevention of fading phenomenon

To prevent the fading phenomenon of hanging tag copperplate paper, the following measures can be taken:

Avoid prolonged direct sunlight: Store the hang tag copperplate paper in a cool, dry environment and avoid prolonged exposure to strong sunlight.

Keep dry: Ensure that the hang tag copperplate paper is in a dry environment and avoid prolonged exposure to moisture.

Avoid contact with chemical substances: Avoid direct contact between the hanging copper plate paper and chemicals such as acids, alkalis, oxidants, etc.

Handle with care: During transportation and storage, avoid physical friction and damage to the copper plate paper of the hang tag.

In summary, the color stability of hang tag copperplate paper is relatively good, but fading may still occur under specific conditions. By selecting high-quality materials, optimizing printing processes, conducting post-processing techniques, and taking preventive measures, the color stability of hanging plate copperplate paper can be effectively improved, and its service life can be extended.
