Flexographic printing system features 1) Compared with gravure and offset, flexo density curve instability, plate thickness variation for print quality has a greater impact, which increases the difficulty of flexo color overprint. 2) flexographic printing using anilox ink transfer plastic plate, the plate must match the network cable and the number of lines of the anilox roll, otherwise it will create a small point of light district into a high hole printed ink does not come out, while the four-color version screen angle can not use 45 °, or easy to produce moire. 3) dot gain more serious, because of low hardness flexo platemaking, graphics easily deformed by extrusion, printing process, dot gain more serious. A general increase in the range of 16% -30%, up to 50% midtone, 2% -3% of the network increased to 15% or even higher. Therefore, the print is difficult to guarantee tonal level, resulting in a high profile throughout the version level to develop into a darkened part of the field, the network appears hollow, not smooth. Network-level changes makes the image a serious cast, the whole picture looks level is unknown, unclear, difficult to show subtle level, three-dimensional sense is not strong. Under the influence of dot gain, flexographic printing out the image 10% below the high level of serious loss of light, more than 85 percent level easily become darkened field. 4) Because of the flexographic printing pressure is small, a slight change in the pressure will be on the print quality produce significant control change carton printing plate, embossed force becomes very important. 5) the need to re-set the parameters of the plate separation manufacturers can not copy the offset or gravure. At present, China imported mostly flexo equipment unit type, unit generally have 6-8, plus the packaging industry more use of spot color, so the separation flexo multicolor separations to be considered in order to compensate for printing inadequate access point performance. Photosensitive resin version features photopolymer flexographic also known as photosensitive resin. Its main advantage is the plate-making process is simple, fast loading version, anti-Indian rate, good ink transfer performance, the plate faster than hand-carved and cast rubber version is much faster, more stable print quality. Photosensitive resin has both liquid and solid, the liquid photosensitive resin in the molding apparatus, the liquid photosensitive resin is molded according to a desired thickness plate. It has no pollution, low cost, high production efficiency features, more suitable for text, lines mainly monochrome prints and lower quality prints. The presence of liquid photosensitive resin is easily deformed, the shortcomings of poor print reproduction. The solid resin version is by plate production plant in advance of the photosensitive resin, coated on a thin metal plate or polyester films such as substrate, made of uniform thickness plates. The plate latitude better able to reproduce the finer dot high light levels, its expansion rate than the rubber version and liquid resin version is much smaller, it is more suitable for the production of textured version and line edition. However, the solid resin version of the more expensive, production costs are relatively high. Therefore, more suitable for printing bulk packaging products Zhengzhou Dunlop advertising (Figure), flexo platemaking, Ma'anshan plate provided by Dunlop Advertising Co., Ltd., Zhengzhou.
