What are the printing methods of self-adhesive coated paper?

There are a variety of printing methods of self-adhesive coated paper, mainly including the following:

1. Lithography printing

Principle: Graphic information is engraved on a flat printed plate, and then the pattern is transferred to the surface of the material by coating ink to form a printed matter.

Features: printing speed, low cost, and high color reproduction, suitable for monochrome and multi-color printing.

Application: Widely used in the printing of self-adhesive coated paper, can meet the printing needs of most labels.

2. Relief printing

Principle: The graphic information is thickened and raised in the printing plate, so that it is flat with the part outside the printing plate. When printing, the graphic information on the relief plate shall prevail, and the printing ink shall be pressurized to transfer the pattern to the surface of the material to form a printed matter.

Features: large printing thickness, strong color, suitable for products requiring high visual effects.

Application: Although the cost is relatively high, letterpress printing is still an important printing method in the printing of self-adhesive coated paper that requires strong visual effects.

3. Screen printing

Principle: The use of gauze brush ink printing, brush coating, roller rotation and other ways to transfer the ink to the surface of the material, the formation of printed matter.

Features: Suitable for labels with small printing amount, and the application of screen printing is wide, and can print delicate and uniform patterns and text.

Application: Screen printing has unique advantages in small-batch self-adhesive coated paper printing that requires high-precision printing.

4. Other printing methods

In addition to the above three main printing methods, the printing of self-adhesive coated paper may also involve intaglio printing, flexo printing and other printing methods. These printing methods have their own characteristics and are suitable for different printing needs and scenarios.

Matters needing attention

Ink control: Because the surface of the coated paper is specially treated, it has good inking, but the ink absorption is moderate, so it is necessary to control the ink amount during printing to avoid printing problems caused by too much or too little.

Drying treatment: The self-adhesive coated paper after printing needs to be properly dried to ensure that the ink is completely dry and attached to the surface of the paper, improving the durability and beauty of the print.

Die-cutting and laminating: After printing is completed, self-adhesive coated paper usually needs to be die-cutting and laminating and other subsequent processing processes to meet different use needs.

In summary, there are a variety of printing methods of self-adhesive coated paper, each of which has its own unique characteristics and scope of application. In practical applications, the appropriate printing method should be selected according to the specific printing needs and scenarios.
