What are the common processes of self-adhesive label printing

There are a variety of common processes for self-adhesive label printing, and each process has its own unique characteristics and application scenarios. The following are some common self-adhesive label printing processes:

1. Printing method

Letterpress printing: photosensitive resin letterpress, using water-based ink or UV ink suitable for flexographic printing. This printing method is suitable for large-area, solid color block printing, which can present bright colors and patterns. (Source: Hundred)

Intaglio printing: The use of short ink path ink delivery system, suitable for web printing. Gravure printing machine speed is high, but the plate making cycle is long, expensive, suitable for mass label production. (Source: Baidu Encyclopedia)

Lithography (offset printing) : The use of ink and water on the printing plate mutually exclusive principle of printing, fine graphics, rich layers. Film labels are mostly roll-to-roll printing, which requires volatile drying inks and is suitable for mass printing. (Source: Baidu Encyclopedia)

Flexographic printing: The machine structure is simple, low cost, using water-based ink and UV ink, does not pollute the environment, suitable for a variety of self-adhesive materials printing. (Source: Baidu Encyclopedia)

Screen printing: The ink is transferred to the substrate through the mesh on the screen plate, which is suitable for printing large-area, colorful patterns and text, and the permeability of the ink is good, which can show a more delicate printing effect. (Source: Hundred)

2. Special craft

Hot stamping/hot silver: Using the principle of hot pressing transfer, the coating is transferred to the surface of the substrate to form a special metal effect, more printed on the LOGO, product name, to enhance the texture and grade of the label. (Source: Hundred)

Coating: The surface of the label is covered with a layer of transparent plastic film, which is divided into bright film and dumb film, to protect the sticker, increase luster, extend service life, and improve wear resistance and water resistance. (Source: Hundred)

Glazing: Apply a layer of gloss oil on the surface of the label to make the surface of the label smoother and increase the gloss and waterproof performance. Glazing is divided into overall glazing and local glazing, and local glazing can achieve the purpose of increasing the local luster and contrast effect. (Source: CSDN blog)

Embossing: The embossing pattern is formed on the surface of the label through the molding process, which enhances the three-dimensional sense and touch of the label and improves the visual impact. (Source: Summary)

Die cutting: Die cutting according to the design shape of the label to remove excess paper and form the final label shape. Die cutting is flat die cutting and circular die cutting, the latter has higher precision and faster speed. (Source: CSDN blog)

3. Other crafts

Punch holes: Punch holes at specific positions of labels for positioning and driving, mainly used in large labels such as pricing machines, printing labels and price guns. (Source: CSDN blog)

Waste removal: the paper edge around the label is removed after die cutting, so that the label can be automatically labeled or manually labeled, which is a unique process in the processing of self-adhesive labels. (Source: CSDN blog)

In summary, the common process of self-adhesive label printing includes a variety of printing methods and special processes, each process has its own unique application scenarios and advantages. When selecting the self-adhesive label printing process, it is necessary to comprehensively consider the use, material, quantity, budget and other factors of the label to ensure that the printing of high quality and meet the needs of the self-adhesive label.
