How does the surface gloss of self-adhesive coated paper affect printing?

The surface gloss of self-adhesive coated paper has a significant impact on printing, mainly reflected in the following aspects:

1. affect the gloss of printed matter

Gloss performance: The self-adhesive coated paper is super calender, and the surface gloss is high, which makes the ink better attached to the paper during the printing process, and reflects a brighter and brighter color. High-gloss coated paper prints can give people a visual enjoyment and enhance the overall texture of the product.

The relationship between gloss and smoothness: The gloss of a paper is usually closely related to its surface smoothness. The surface smoothness of coated paper is high, which can reduce the diffusion of ink in the printing process, making the printing pattern more clear and sharp. At the same time, the smooth surface of the paper also helps improve the color saturation and contrast of the print.

2. affect the drying speed of printing ink

Ink absorption and drying speed: The ink absorption of coated paper is moderate, neither too strong nor too weak, which helps the ink to adhere evenly on the paper and dry quickly. If the ink absorption of the paper is too strong, the ink is easy to be quickly absorbed into the inside of the paper, resulting in a slow drying speed and ink infiltration on the surface of the print; On the contrary, if the ink absorption is too weak, the ink is difficult to adhere to the paper, affecting the printing effect.

Gloss and ink absorption balance: High gloss coated paper is often specially treated to improve the balance between its surface smoothness and ink absorption. This balanced state helps the ink maintain a stable adhesion and drying rate during the printing process, thus ensuring the quality of the print.

3. affect the visual effect of printed matter

Color reproduction: high-gloss coated paper can better restore the color of printed matter, making the pattern and text more vivid and vivid. This enhancement of color reproduction ability helps to enhance the attractiveness and market competitiveness of the product.

Texture enhancement: In addition to color restoration, high-gloss coated paper can also enhance the overall texture of the print. Smooth, bright paper gives people a high-grade, refined feeling, help to enhance the brand image of the product and added value.

4. Precautions

Choose the right printing method: Different printing methods have different effects on the gloss and printing effect of coated paper. Therefore, when selecting the printing method, it is necessary to comprehensively consider the specific needs and characteristics of the coated paper.

Control of printing parameters: In order to give full play to the gloss advantage of coated paper and ensure the stability and consistency of print quality, it is necessary to strictly control the parameters in the printing process such as ink viscosity, printing pressure, speed and so on.

In summary, the surface gloss of self-adhesive coated paper has many effects on printing. In practical applications, it is necessary to select the appropriate printing methods and parameters according to the specific needs and characteristics of coated paper to give full play to its advantages and ensure the quality of printed matter.
