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, printing network cable must match 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 of the screen angle can not using 45 °, or easy to produce moire. 3) dot gain more serious, because of the low flexographic hardness, 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 a resin plate making, darkened areas become field, dot 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 of the printing quality will produce significant changes in the imprint pressure control becomes very important. 5) the need to re-set the color separation parameters, can not copy offset or gravure. At present, China imported mostly unit type flexo platemaking equipment manufacturers generally have 6-8 units, plus the packaging industry more use of spot color, so the separation flexo multicolor separations to be considered in order to compensate for printing internet point performance deficiencies. Plate resin version of the basic information printed in the edition of flexible material, used for sticker printing plate, when you copy a film to be a female piece, by UV exposure, rinse and made the prototype liquid version with solid version of the points The exposure principle to produce printing plates. Resin plate making process photosensitive resin letterpress printing plate, is photosensitive resin material, through exposure, rinse and polymeric light relief, it phototypesetting, computer typesetting technology, not only improves the speed of the plate, and thoroughly The abandoned lead alloy plate, so that the "cold row" more perfect for letterpress printing to create a new way. Photosensitive resin plate, according to the form of the resin before molding, can be divided into liquid and solid research of curing type two categories.
