Special Note: This information is for reference pictures and information, please contact us to obtain the most accurate information, thank you! The photosensitive resin letterpress, based on a photosensitive resin material, through exposure, washing and light polymeric letterpress plate making, it phototypesetting, computer typesetting technology, not only improves the speed of the plate, and completely abandoned lead alloy India version, so that the "cold row" more perfect for letterpress printing to create a new way. The photosensitive resin letterpress is photosensitive resin as expected, by exposure, rinse and photopolymerizable relief, it phototypesetting, computer typesetting technology combined with flexo plate making, not only improves the speed of the plate, and completely abandoned lead alloy plate, so that the "cold row" more perfect for letterpress printing to create a new way. 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, transparent film covering plate manufacturers, and put on a positive Negative 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 flexographic plate, wash 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 of the photosensitive resin plate is rinsed, and placed in an infrared drier. After drying the photosensitive resin plate, and then after the first exposure, the aim of increasing the mechanical strength of the plate and improve pressrun. Liquid resin version, type version of belonging that is coated, 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.
