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:

First, the gloss and visual effect of printed matter

Gloss enhancement: The surface of the self-adhesive coated paper is specially treated to have a high gloss. This high gloss allows the print to reflect a bright gloss when exposed to light, thereby enhancing the overall visual effect of the print, making it look more exquisite and upscale.

Color brightness: The high gloss surface can better reflect the light, making the color of the print more vivid and full. This helps to increase the appeal and recognition of the print, making it stand out among many products.

Second, ink absorption and drying speed

Ink absorption: The smoothness and gloss of self-adhesive coated paper will affect its absorption of ink. In general, coated paper with high surface smoothness and good gloss has relatively weak ink absorption, which helps to avoid excessive ink penetration into the inside of the paper, resulting in reduced gloss or powder phenomenon of the print.

Drying speed: Because the surface of the self-adhesive coated paper is smooth and the ink absorption is moderate, the drying speed of the ink on the surface is relatively fast. This helps to improve printing efficiency and reduce printing quality problems caused by poor ink drying.

Third, printing accuracy and dot reproducibility

Printing accuracy: The high smoothness and gloss of the self-adhesive coated paper allow it to be in close contact with the plate, thus ensuring the accuracy of the printing process. This helps to achieve fine printing results and reduce problems such as blurring and ginning caused by insufficient printing accuracy.

Dot reproducibility: The surface particles of high-gloss coated paper are small and evenly distributed, which makes it have good dot reproducibility. In the printing process, it can clearly reproduce small dots and image details to ensure the clarity and layer of the print.

Fourth, practical application scenarios

High-grade printing: Because the self-adhesive coated paper has excellent gloss and printing effect, it is widely used in the field of high-grade printing, such as cosmetics labels, drug labels, food packaging labels, etc. These areas have high requirements for the quality and visual effects of printed matter, and self-adhesive coated paper can meet these needs.

Special needs scenarios: In some special needs scenarios, such as the need for high gloss promotional labels, certificate labels, etc., self-adhesive coated paper is also an ideal choice. Its excellent gloss and printing effect can attract the attention of consumers and improve the market competitiveness of products.

In summary, the surface gloss of self-adhesive coated paper has many effects on printing. When selecting self-adhesive materials, it is necessary to comprehensively consider its gloss and other related properties according to the specific printing needs and application scenarios.
