Chromium removal
There is a discontinuous or continuous chromium layer falling off in a certain area of the plate roller body, which directly affects the graphic information of the product and cannot be printed.
The main reason for chromium loss is that the thickness and treatment effect of the plate roller are not up to standard. In addition, poor storage environment, operation, maintenance and cleaning in the later stage of printing will cause chromium loss. At present, many flexible packaging enterprises are talking about the concept of cost saving, plate making factory also has such a concept. In the selection of roller suppliers, enterprises should not only consider the price, but also consider the quality. On the market, some plate making factories cost 0.13 yuan per square meter, some say I can only pay 0.1 yuan, and others are lower. It is true that some enterprises may have cost space in technology and management, so that they can compete at a lower price in the market while ensuring quality. However, this is only a small number of low-cost plate rollers, and the treatment of chromium layer has a certain deviation from the thickness, followed by the overall luminosity of the plate roller, and the quality of both ends of the dot and plug will also have deviation. So we have to choose high-quality suppliers, in order to ensure our product quality and plate roller quality, reduce losses.
It is suggested that enterprises choose suitable quality, price and reputation of flexible packaging roller suppliers to cooperate. The plate roller should be placed vertically, the roller body should be wrapped with breathable plastic film, and the outside should be wrapped with corrugated paper, and placed in the designated area. The plate room should be dry and ventilated without moisture. Operators are not allowed to directly touch the roller body by hand, and special tools should be provided for protection. The roller body should be protected by special antirust oil.
