Environmental flexo printing plates cited compelling "refurbished articles" As global environmental problems increasingly grim, how to achieve "environmentally friendly" sustainable development, as businesses are considering. And thanks to this background factors, flexographic printing to other printing methods can not match the environmental advantages, the printing process has become one of the fastest growing printing. Flexography printing accounted for about 30% of the global packaging market share, especially in North America, Western Europe and other regions, flexographic printing in packaging applications is extensive. Flexographic printing using environmentally friendly water-based, alcohol resistance, UV inks, reducing VOC emissions carton printing plate, flexo inks simultaneously very thin very thin, so it does not inorganic pigments and fillers, rarely heavy metal residues. In the United States, flexo water-based ink is currently the only approved by the US Food and Drug Association nontoxic ink, is widely used in food and pharmaceutical packaging printing. And one of the key factors as the flexographic printing quality assurance, quality flexographic printing plates, the process is also with the market demand continues to increase. Currently plates for conventional flexographic printing mainly rubber and resin version version two. Rubber version can be divided into natural rubber, synthetic rubber and mixing rubber. Its plate methods are using hand engraving, laser engraving and molded cast of three. The resin version, also known as photosensitive resin plate, is a synthetic polymer material as a film-forming agent, unsaturated organic compounds as photocrosslinker, prepared letterpress plate having a photosensitive properties. Based on the needs of the chemical properties and markets, to develop a post-1975 years ago, two different types of plates, namely a combination of saturated resin made of solid light sexy series prefabricated plate (solid version) and unsaturated polyester The liquid resin type series that is coated plates (liquid version). Nearly 30 years, from the traditional hand-carved steering photopolymer flexographic flexographic, flexo platemaking technology is an important leap. How to extend the life of the flexographic printing plate this time, it should be noted that: photopolymer flexographic printing inks and cleaning liquid version only certain types of matches if the wrong type or model of the solvent content is too high, but it will cause the plate expansion, contraction or cracking. When using a higher concentration of pigment water-based flexo ink, if the ink in the printing cylinder or anilox surface dry, will accelerate the plate wear. PH of the water-based ink is generally controlled at about 9.0, a bit more basic. If the pH is too big to fall, it will lead to a change thixotropic ink and thickens, easy xerophthalmia and difficult to re-dissolve. The dried ink film peeling friction plates, to accelerate the wear plates. Further, the kind of the antifoaming agent will affect the life of the printing plate. For example, water-based defoamers compared with silicone defoamers, easier to shorten the flexographic life. Because water-based defoamers more likely to cause plate expansion or cracking. ⑵ solvent Many people may have noticed, flexographic printing plate is more likely to occur in the summer than in the winter cracking. Summer, a lot of changes in the environment result in cracking of the plate acceleration factor. First, the temperature, increasing the quantity of the ink coated plates expand. Secondly, the increase in humidity in summer, in order to ensure good flow of the ink, the ink must be increased in the acetate content, thereby increasing the plate corrosion and shorten the life of the printing plate. Furthermore plate manufacturers, summer lightning storms more, will produce large amounts of ozone, photopolymer flexographic very sensitive to ozone, exposure to ozone can easily produce plate some small cracks plate, resulting in not printing. However, when the ozone concentration is low, the main factors to accelerate the cracking of the printing inks and printing acetate salt solvent containing cleaning agent is too high. In the actual printing, ink and wash dosage many printing operator actually used far beyond the recommended value platemaking experts. If it is in the winter, it may not be a problem, but in the summer, the problem is much more serious. ⑶ substrates more rough substrate surface, the greater the friction between the plates, the plates wear sooner. ⑷ printing pressure Zhengzhou Dunlop advertising (Figure), plastic plate, the plate is provided by Dunlop Advertising Co., Ltd., Zhengzhou.
