Detailed Product Description: | 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 the pigment water-based flexo ink carton printing plate, 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 changes and thickens thixotropic ink letterpress plate making, 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 plate, compared with an aqueous silicone defoamers 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 summer humidity increases, in order to ensure a good flow of ink flexographic platemaking, we must increase the ink acetate content, thereby increasing the plate corrosion and shorten the life of the 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, 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 pressure flexographic printing plate processing rules for storing basic media, the proper storage and management is very important. Here at sub-plate, and enjoyed plates and finished plates in the case before a brief introduction about flexo storage and management. First, when the factory plate, plate processing storing basic rules are as follows: 1, unexposed plate placed inside the box, with the contact surface of the black plastic film bag properly can not be placed in front of the uneven film exposure before peelable surface of the sheet after peeling, if over-bend, make a protective layer wrinkling, these wrinkles plate after exposure, it will stain 2, the exposed plate: Be careful treatment to a cardboard mat anti below with the original surface of the sheet bend light cover above protection 3, washout after wetting the plate to avoid contact with the resin surface, otherwise it will form a stain treatment, avoid inhalation of solvent vapors plate | Zhengzhou Dunlop Advertise | printing plate from Zhengzhou Dunlop Advertising Limited.
