Flexographic printing errors domestic packaging and printing companies use in the treatment of flexographic printing suitability of the product, they often into errors: First, the flexo process incomplete understanding of the characteristics of flexo insufficient understanding, habitually go with offset and gravure clarity and graded levels compared to higher network cable outlets. Secondly, the lack of proper quality evaluation criteria flexo, and communication between the customer is no uniform standard, cause some misunderstandings and disagreements. Third, is the lack of professional flexographic designers, operators and marketing personnel, can not take full advantage of flexo products, such as ink film thickness and color saturation. Fourth, there is no linkage between flexo printing machine to play a strong advantage, the combination of a variety of printing and finishing processes, improve productivity and reduce costs. Print margins and integration costs for lack of knowledge, most of the domestic packaging and printing companies are still in the stage of extensive business management, assessment and cost for prints profits are not integrated systems and norms liquid resin platemaking process liquid resin platemaking process generally flow through the shop, exposure, washing, drying and post-exposure and other processes. (1) The prepared spread flows are photosensitive resin, exposing the injection molding machine hopper. Photosensitive resin flows out from the hopper, the hopper at the top of the blade, the flow out of the photosensitive resin scraped into a certain thickness. (2) the exposure is spread on a photosensitive resin flow, covering a transparent film, and put forward a negative on the film, the first for the positive exposure, after back exposure. Under the master exposure time is usually 10 times on the back of the exposure time. Common ultraviolet high pressure mercury lamp as a light source rich. (3) washing the exposed photosensitive resin plate was placed in a washing machine letterpress plate, washed with dilute sodium hydroxide solution (concentration of about 3 to 5%), as maintained at about rinse 35 ℃. No photopolymerizable light does not occur, the resin is dissolved crosslinked, hardened film of the photosensitive leaving the graphic part. (4) drying and post-exposure is to wash after photopolymer plate making, into the infrared drier. After drying the photosensitive resin plate, and then after the first exposure, the aim is to increase the mechanical strength of the resin plate plate making, improve anti-Indian forces. Liquid resin version, type version of belonging that is coated plastic plate, low prices, poor dimensional stability, layout stretching pregnant influenced by the temperature and humidity, suitable for the production of smaller lines or text format printing, the main body of the printed book.
