UV flexo printing originated from label printing. At first, low-speed narrow web rotary printing machines were mostly used to print self-adhesive labels, and a 300W/line inch medium-pressure mercury vapor lamp was used to obtain a satisfactory curing effect.

The four-color printing mode is a color registration mode used in color printing. It uses the principle of color mixing of three primary colors of color materials, plus black ink, and a total of four colors are mixed and superimposed to form the so-called "full-color printing". The four standard colors are: C:Cyan = cyan, also known as 'sky blue' or 'blue'; M:Magenta = magenta, also known as 'magenta'; Y:Yellow = yellow; K:blacK= Black, although some literature explains that the K here should be Key Color (positioning and registration color), but it is actually confused with the concept of positioning and registration used in plate making. The abbreviation here uses the last letter K instead of the beginning B to avoid confusion with Blue. The CMYK mode is a subtractive color mode, and the corresponding RGB mode is an additive color mode

UV flexo printing is a type of flexographic printing that uses ultraviolet (UV) light to cure the ink.

Label printing is the process of creating labels with text, images, and other graphics. Labels are used to identify, track, and market products and services. They can be found on a wide variety of items, including food, clothing, electronics, and medical supplies.

Powder coating is to use powder spraying equipment (electrostatic spraying machine) to spray powder coating on the surface of the workpiece. Under the action of static electricity, the powder will be evenly adsorbed on the surface of the workpiece to form a powder coating; the powder coating is baked at high temperature. Bake leveling and curing, and become the final coating with different effects (different types of powder coatings); the spraying effect of powder spraying is better than that of spray painting in terms of mechanical strength, adhesion, corrosion resistance, aging resistance, etc., and the cost is also higher. Under spray paint with the same effect.
