How to improve the durability of colored copperplate label paper?

To improve the durability of color copperplate label paper, you can start from the following aspects:

First, choose high-quality materials

Paper selection: high-quality coated paper is used as the base material to ensure that it has a high coating strength and uniformity to reduce the phenomenon of depowder and hair loss during the printing process. Consider using double-tape paper with good toughness or other special materials.

Ink selection: Select light, heat and chemical resistant inks to ensure that the label can maintain a clear printing effect in a variety of environments.

Second, optimize the printing process

Adjust the printing pressure: ensure that the printing pressure is uniform and appropriate to avoid deformation or damage to the paper caused by excessive pressure.

Control the amount of ink: the printing method of "deep ink thin printing" is used, that is, the appropriate darkening of the ink color, while reducing the thickness of the ink layer to improve the printing effect and durability.

Strengthen anti-stick treatment: Add an appropriate amount of anti-stick agent in the printing process to prevent ink adhesion and poor drying, and improve the cleanliness and durability of the label.

Third, strengthen post-processing

Glazing treatment: After the printing of the label is completed, it can increase the gloss and smoothness of the label surface, and improve the wear resistance and scratch resistance of the label.

Coating treatment: Cover the label surface with a layer of protective film, can effectively prevent moisture, oil and scratch damage to the label, extend the service life of the label.

Fourth, use special technology

UV curing technology: The use of UV curing ink and UV curing equipment can make the ink quickly dry and cure on the surface of the paper, forming a hard protective layer and improving the durability of the label.

Hot stamping technology: For labels that require higher durability, hot stamping technology can be used to hot print metal foil or other special materials on the surface of the paper to form a strong protective layer.

Fifth, pay attention to the storage and use environment

Storage environment: Store the labels in a dry, cool, and well-ventilated environment to avoid direct sunlight, high temperature and humidity.

Use environment: In the process of use, avoid long-term contact with water, oil and sharp objects that may cause damage to the label.

To sum up, improving the durability of color copperplate label paper needs to start from many aspects such as material selection, printing process, post-processing, special technology application and storage and use environment. By comprehensively considering these factors and taking corresponding measures, the durability of the label can be significantly improved and its service life can be extended.
