What are the printing processes for copperplate adhesive labels?

The printing process of copperplate adhesive labels mainly includes the following:

1、 Offset printing process

Offset printing is one of the commonly used printing processes for copperplate adhesive labels. It uses rubber blankets to transfer ink to the surface of paper, achieving printing of graphic and textual information. Offset printing technology has the advantages of high printing quality, good color reproduction, and strong adaptability, making it very suitable for printing exquisite and detailed graphic and textual information.

2、 Flexographic printing process

Flexographic printing technology uses flexographic plates for printing and is suitable for various types of paper and substrates. The flexographic printing process has the characteristics of high printing pressure, thick ink layer, and bright colors, making it particularly suitable for printing large areas of solid and dot spaces. In addition, flexographic printing technology also has the advantages of environmental protection, energy saving, and low cost, so it is widely used in copperplate adhesive label printing.

3、 Gravure printing process

The intaglio printing process uses intaglio printing, where the graphic and textual parts on the intaglio are lower than the non graphic parts. The ink is scraped into the pits by a scraper and then transferred to the surface of the paper. The gravure printing process has the advantages of high printing accuracy, full ink color, and rich layers, making it particularly suitable for printing high-quality, high value-added copperplate adhesive labels.

4、 Film coating process

The laminating process is to cover a layer of transparent plastic film on the surface of printed materials to enhance the waterproof, oil resistant, wear-resistant and other properties of the label. The laminating process is divided into two types: bright film and matte film. Bright film can increase the glossiness and brightness of the label, while matte film makes the label look more stable and high-end. The laminating process is widely used in the production of copperplate adhesive labels, which can greatly improve the durability and aesthetics of the labels.

5、 Hot stamping/silver stamping process

The hot stamping/silver stamping process utilizes the principle of hot press transfer to transfer metal coatings onto the surface of the substrate, creating a special metallic effect. This process is commonly used for printing key information such as logos and product names, which can increase the aesthetic and high-end feel of labels.

6、 Die cutting process

Die cutting process is to use molds to cut labels into different shapes and sizes according to the design requirements of the labels. The die-cutting process ensures that the edges of the label are flat and smooth, making it easy to stick to various items. In the production of copperplate adhesive labels, die-cutting process is one of the essential steps.

7、 Other printing techniques

In addition to the main printing processes mentioned above, copperplate adhesive labels can also use special processes such as UV printing and embossed printing. UV printing can increase the glossiness and three-dimensional effect of labels; Embossed printing can create various textures and patterns on the surface of labels, increasing the tactile and visual effects of the labels.

In summary, there are various printing processes for copperplate adhesive labels, which can be flexibly selected based on factors such as the specific purpose of the label, design requirements, and cost budget. Different printing processes have their own advantages and disadvantages, and in practical applications, they need to be comprehensively considered and combined according to the actual situation.
