Zhengzhou Dunlop advertising (Figure) | letterpress plate | plate supplied by Dunlop Advertising Co., Ltd., Zhengzhou. Zhengzhou Dunlop Advertising Co., Ltd. (#) is a professional "flexographic, resin version, print, packaging design," the company. Since its inception, we adhere to the "honesty, sound management" approach, the courage to healthy competition in the market, so that the "Schindler plate" brand has a good reputation. We adhere to the "service first, customers first" principle, so Zhengzhou Dunlop advertisement has won numerous customer's trust in plate making, printing supplies, and establish a good corporate image. Special Note: This information is for reference pictures and information, please contact us to obtain the most accurate information, thank you! Environmental books and sought after books and printing ink industrialization prospects flexographic printing ink (hereinafter referred to as flexo) non-toxic and non-polluting, use free of heavy metals and other toxic substances in green ink, with the environmental characteristics of the plate, has been recognized by the international community greatly . Flexo way in the world flexible packaging printing market has accounted for more than 60 percent in the country is gradually dominate the market. "Textbook flexographic printing ink" is a key project of the State Press and Publication Administration of Radio, 2011 Shanghai Printing (Group) Co., Ltd. started this process of development, in June 2014 the first set of home and children's books printing ink "Listen Dad storytelling "successful printing, sign the final success of the project. However, compared with the traditional offset printing, ink flexo platemaking, there are still high cost of printing dot gain higher reality. Projects to test market acceptance does not mean success, but success does not mean that the industrialization of letterpress plate making, printing ink reflection of how the market is? How social acceptance of ink product? To solve these problems, recently, Shanghai Printing Group Publishing Limited conducted a childlike hand in market research activities. Environmental books and highly sought after. 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 rises flexo platemaking, exacerbated by a large number of ink coated plate expansion. 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. In addition, many summer lightning storms will produce large amounts of ozone, photopolymer flexographic very sensitive to ozone, sheet exposure to ozone can easily produce some small cracks, 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 of the resin plate making, printing ink and cleaning 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
