Self-adhesive label technology is divided into appearance technology, processing technology, and post-labeling technology.

First, the appearance process is the color and texture of the label. When introducing labels, the appearance is usually described as: "transparent, white, metallic, textured, round," etc. The appearance process can preliminarily judge the material and shape of the label.

Second, the processing technology is the printing processing method of self-adhesive stickers. Printing processes include offset printing, flexographic printing, letterpress printing, screen printing, gravure printing, digital printing, and so on. The processing technology includes hob die cutting, planographic die cutting, laminating, glazing, bronzing, punching, folding, and static elimination. Printing processes include thermal printing, thermal transfer printing, laser printing, inkjet printing, etc. Different label types have different processing techniques. Blank label paper is die-cut with a flat knife or a hob. Rolled blank label paper is mostly printed by thermal or thermal transfer, while flat A4 paper stickers are mostly laser or inkjet printed. Label coating can protect the ink and protect it from friction and moisture.
After understanding the process, you should know how to make an inquiry? A simpler question is to ask sales: "Can you produce a hot stamping transparent sticker? You need a 2 * 2cm size." In this way, the other party immediately understood that you want transparent labels and you need bronzing, and the trademark LOGO stickers are all round oval.

Third, the later labeling process, many people do not understand. In fact, some stickers need to be processed after being affixed. For example: label ceramic glass products need permanent curing after 300 degrees high temperature for 30 minutes; in addition, tire vulcanization labels are also vulcanized after being affixed to the tires.
