Packaging printing technology: UV curing ink printing

  UV is the abbreviation of "Ultraviolet Rays" in English. The so-called UV ink refers to the ink that can undergo cross-linking polymerization reaction under ultraviolet irradiation and can instantly solidify into a film. UV ink can be used in flexographic printing, offset printing, gravure printing, and silk screen printing. Among them, it is relatively widely used in offset printing, flexographic printing and silk screen printing.

  Driven by the dual waves of greening and intelligence, UV ink printing technology is reshaping the packaging and printing industry with its unique advantages of "high-efficiency curing + zero pollution". From the scratch-resistant and high-temperature-resistant UV metal ink on Wanglaoji metal cans to the high-speed adaptation of LED curing technology in single-channel printing of corrugated paper boxes, this technology has broken through the limitations of traditional processes - the environmentally friendly characteristics of no solvent volatilization make it the first choice for food and medicine packaging.

  The ability to cure instantly within 1 second has greatly improved printing efficiency and color expression. With the decline in the cost of UV-LED light sources and the maturity of functional inks (such as 3D textures and temperature-changing effects), packaging printing is transitioning from "visual communication" to "sensory experience."

  The printed product has low energy consumption and can be dried instantly. The printed product has no odor. The ink consumption is small, the waste is small, and the environmental pollution is small. The ink film of UV ink has good wear resistance, corrosion resistance, and weather resistance, and the gloss after printing is good and the color is bright.

  It is worth noting that in order to ensure the ultraviolet light intensity of the UV lamp, it is necessary to control the water-ink balance well, and adjust the ink dosage and color sequence according to the characteristics of UV ink.
