What are the common printing methods of self-adhesive copper plate label paper?

Self-adhesive copper plate label paper is commonly printed in a variety of ways, mainly including the following:

1.Letterpress printing: Letterpress printing is a common way of self-adhesive label printing. It uses a raised graphic part for printing, the graphic part is higher than the blank part, when printing, the graphic part is dipped in ink, and then transferred to the substrate. Letterpress printing has the characteristics of full ink, bright color, clear graphics and so on, which is very suitable for printing text, line or field color block.

2.Lithography (offset printing) : Lithography is also a common printing method in self-adhesive label printing. It uses the principle of insolubility of oil and water to keep the graphic part oilophilic and the blank part hydrophilic, so as to realize the graphic printing. Lithographic printing has the advantages of fast printing speed, stable printing quality and suitable for mass printing.

3.Gravure printing: Gravure printing is a deep printing method, the graphic part is lower than the blank part, when printing, the ink is filled into the pit, and then the excess ink is scraped away by the scraper, and finally transferred to the substrate. Intaglio printing has the characteristics of thick ink layer, bright color, strong layering, etc., especially suitable for printing high-quality pictures and complex graphics.

4.Screen printing: Screen printing is a way of printing through silk mesh. When printing, the ink is poured on the screen, and the scraper is used to scrape and press, so that the ink is transferred to the substrate through the mesh. Screen printing has the characteristics of wide printing range, thick ink layer and strong three-dimensional sense, especially suitable for printing labels on large patterns, special materials or curved objects.

5.Combination printing: In practical applications, in order to improve the printing effect and meet different printing needs, combination printing is often used. It is to combine a variety of printing methods, such as letterpress plus screen, flexible printing plus screen, offset printing plus screen, etc. Through combination printing, you can give full play to the advantages of various printing methods, so that the label graphics are more beautiful and three-dimensional.

It should be noted that the choice of printing method mainly depends on the specific requirements of the label, printing costs and production efficiency and other factors. Due to its good printing adaptability and inking, self-adhesive copper plate label paper can adapt to the above various printing methods, so as to meet various printing needs.
