Under the green wind, poster printing related manufacturers also began to enable more environmentally friendly ink, although higher costs, but in response to the call of the low carbon and environmental protection, the UV ink was widely used, and then compared with ordinary ink, UV ink mainly what advantages? 

(1) fast drying, excellent performance. UV ink in UV light irradiation, only 1/10 seconds to a few seconds can be completely dry curing, fast speed. In online printing transmission can be dried to ensure printing can be carried out immediately after processing, for processing, saving the product cycle. In addition, the UV ink only under the irradiation of ultraviolet light will dry, ink in the printing process even in the fountain in the long-term storage, its performance can also remained stable, also won't appear in ink crust phenomenon. 

(2) to save energy and meet environmental protection. Than in addition to the natural evaporation of dry ink any ink, more energy saving, less waste. Compared with traditional ink, UV ink polymerization drying to more thoroughly, the ink curing solid content is close to 100%, no any solvent evaporation or contaminants, ink film 100 percent curable, almost does not contain VOC, namely the curing process does not or very little emit volatile organic compounds, will not cause strong environmental pollution hazards, make the printing environment air is fresh, low odor, is conducive to environmental protection and health of workers, on the environment no pollution, meeting requirements of environmental protection and green printing is a kind of environmental friendly ink. In addition, the ink high flash point (100 degrees Celsius), not easy to burn, save energy, safe use. 

(3) the equipment covers an area of small. Compared with thermal drying, the drying device occupies less area. Printing assembly line, save manpower, economic benefits. Ordinary printing machine using UV ink need to be prepared to do 

(4) in the case of the same dry film thickness, the printing area is large. In addition, the color stability of the printed matter is good, and the brightness is high. 

(5) ink particles are small, can be printed fine figure. UV ink can provide bright, bright colors and ensure a good print gloss, bright color, the printing ink layer is solid, quick drying and crosslinking, such ink layer has higher wear resistance and chemical resistance. UV ink can be used for the need to wear resistant outer packaging printing. 

(6) printing adaptability is strong, wide range of printing. UV ink can meet to the needs of a variety of substrates, the range is very wide, such as paper printing, plastic printing, tape printing, printed circuit board, chrome version printing, electronic parts, printing, printed on the surface of metal, aluminum foil surface printing. In printing, UV printing ink can be applied to convex (soft) version, gravure, offset printing screen, etc..
