preparation example Construction

[0022] The water-based UV photosensitive adhesive is prepared by the following method:

[0023] First, weigh the above-mentioned components by weight percentage. Next, prepare each component weighed in a container equipped with a stirring device and a heating device: the photoinitiator is slowly and Evenly add to the active monomer, after the photoinitiator is completely dissolved, slowly and evenly add the water-based oligomer, mix well, wherein, control the adding time of the photoinitiator and the water-based oligomer to 25-40 minutes; finally add Additives and diluents, stirred until fully mixed, and obtained after filtration.

[0024]During the spraying process, the contact angle of the water-based UV photosensitive adhesive on the surface of the hydrophilic metal plate base is 0-30 degrees. The inkjet precision of the inkjet printing equipment used is not less than 1440DPI, and if the inkjet precision can reach more than 2880DPI, the resolution of the printing plate ca...

[0027] Step 1. Under the control of the computer, use an inkjet printer or an inkjet printer to spray the water-based UV photosensitive glue on the PS plate that is not coated with a photosensitive layer or the aluminum plate base that has been electrolytically anodized as the substrate, according to the layout information requirements, And an oily information recording area is formed on the surface of the metal plate base. The metal base has a thickness of 0.10-0.15 mm. The plate running servo system is optimized according to the thickness of the selected metal plate base. The format of the inkjet printer or inkjet printer should meet the actual printing needs, and the inkjet precision is 1440DPI.

[0028] The specific process is: generate general printing files, such as PS files or PDF files, on the computer with the graphic information to be printed, and then use the Founder RIP software to process the obtained printing files on the computer. It is divided into four color...

Abstract

The invention discloses an offset print water-borne UV (ultraviolet) photo-sensitive resist jetting plate-making method which comprises the following steps: firstly jetting a water-borne UV photo-sensitive resist on a hydrophilic metal base by using an ink-jet printing device, and forming an oiliness information recording region on the surface of the metal base; and in addition, curing a information recording region on the surface of the metal base by using an ultraviolet lamp, and then printing on the machine. The offset print water-borne UV photo-sensitive resist jetting plate-making method is simple in process, rapid in printing plate drying speed, less in energy consumption, good in printing plate quality, good in printing-resistance rate, and free from environment pollution.

Description

technical field [0001] The invention belongs to the technical field of printing and plate making, and relates to an offset printing water-based UV photosensitive glue spraying plate making method using the principle of inkjet imaging. Background technique [0002] In 1995, computer-to-plate technology, namely CTP technology, came out. This technology no longer requires film development, fixing and other processing processes, and no longer requires manual imposition processes, but directly copies the digital graphic information processed by the computer to the printing plate, realizing the combination of computer typesetting and high-speed plate making The perfect combination has brought a real technical revolution to the plate making process. At the beginning of the birth of CTP technology, the cost of equipment and consumables was high, so the inkjet CTP technology with relatively low cost was born under this premise. Existing ink-jet CTP technology principle is used to c...
