What are the special features of the coating on the surface of colored copperplate label paper?

The coating on the surface of colored copperplate label paper has the following special features:

1、 Coating material

The coating on the surface of copperplate paper generally uses white and delicate clay minerals, such as talcum powder, or glossy paste, matte paste, resin based coatings, etc. These materials can make the surface of paper smoother and more delicate, and give it specific glossiness and color effects.

2、 Coating function

Improving glossiness and smoothness: Coatings can significantly enhance the glossiness and smoothness of copperplate paper, making printed images and text more vivid and clear. This characteristic is crucial for printed materials that require fine images and vivid colors.

Enhanced printing effect: Coatings can provide better ink adhesion and color reproduction, ensuring long-lasting bright colors in printed materials and reducing ink diffusion and penetration, thereby improving the quality of printed materials.

Increasing wear resistance: Resin based coatings and other coating materials have good adhesion and wear resistance, which can protect printed materials from damage and extend their service life.

3、 Coating type and effect

Gloss: It gives the surface of copperplate paper a bright luster and increases the visual impact of printed materials. Suitable for high-end brochures, posters, and other printed materials that require vivid colors to be displayed.

Matte paste: It creates a soft matte effect on the surface of copperplate paper, reduces reflection, and improves reading comfort. Suitable for printed materials such as books and magazines that require long-term reading.

Resin based coating: mainly provides protection and can prevent problems such as wear and fading of printed materials. Suitable for printed materials such as packaging and labels that require long-term storage and use.

4、 Coating selection factors

When selecting the coating for the surface of colored copperplate label paper, the following factors need to be considered:

Usage of printed materials: Select appropriate coatings based on the purpose and scene of the printed materials. If you need high brightness and bright colors for printed materials, it is suitable to choose glossy paste; For printed materials that require long-term reading, matte paste is suitable for selection.

Printing process: Different printing processes have different requirements for coatings. Printing processes such as offset printing and gravure printing have high requirements for coatings, and it is necessary to choose coatings with good adhesion and wear resistance.

Cost budget: The price of coatings varies depending on the type and quality, and suitable coatings need to be selected based on the cost budget.

In summary, the coating on the surface of colored copperplate label paper has significant advantages in improving glossiness, smoothness, printing effect, and wear resistance. By selecting appropriate coating materials and types, it is possible to meet the needs of different printed materials and improve the overall printing quality.
