How many levels is the surface gloss of colored copperplate label paper?

The surface gloss of color copperplate label paper can be divided into several levels according to the treatment method, coating material and calender process. In general, gloss is determined by the flatness of the surface of the paper, and is related to the type of fiber, the degree of beating and calendering, the content ratio of the filler and the sizing method. The following is an overview of the surface gloss level of colored copperplate label paper:

Gloss level classification

1.Highlights:

High gloss, excellent surface smoothness, can reflect bright light.

Common high-gloss coated paper includes mirror coated paper, glossy paper and so on.

This grade of paper is usually used for prints requiring high gloss and bright color effects, such as high-end packaging boxes, album covers, etc.

2.Semi-highlights:

The gloss is moderate, between highlight and matte.

Common semi-gloss coated paper, such as ordinary coated paper, has a certain gloss on the surface, but it is not as strong as the highlight paper.

Suitable for prints that need a certain gloss but do not want to be too harsh, such as book covers, posters, etc.

3.Matte (or no light) :

The gloss is low, the surface is relatively rough, and the light reflects less.

Matte coated paper, such as offset paper, gives a soft, low-key feeling.

Suitable for prints that need to reduce reflection, protect eyesight or create a specific atmosphere, such as textbook pages, notebook covers, etc.

Gloss is a specific numerical indicator, usually measured by a gloss meter. For coated paper, the gloss can range from dozens to more than one hundred. In general, the common gloss range of coated paper is 70-90, and the gloss of high-grade coated paper can reach more than 100. These values are for reference only, the actual gloss may vary depending on the paper brand, production process and other factors.

Matters needing attention

When selecting color copperplate label paper, the appropriate gloss level should be selected according to the specific application scenarios and needs.
