Abstract

The invention discloses a fountain solution application method and system based on magnetization as well as an application. The method comprises the following steps that 1) a fountain solution is magnetized firstly, and then the magnetized fountain solution is added into a fountain; 2) a form damping roller part is in contact with the magnetized fountain solution; and 3) a form damping roller is started, so that the fountain solution is made to be continuously and uniformly conveyed to a forme from the form damping roller in the form of a water film. According to the fountain solution application method and system based on magnetization as well as the application, the principle of magnetization is creatively adopted to carry out the application of the fountain solution, the surface tensionof the fountain solution can be greatly reduced, the water film can be stably and uniformly formed on the surface of the form damping roller in an attached mode, the use amount of surface active substances including alcohol in the fountain solution can be greatly reduced, even no surface active substances need to be added for realizing high-quality printing, and high efficiency and environmentalfriendliness are achieved.

Description

technical field [0001] The invention belongs to the technical field of printing, and in particular relates to a method for applying dampening water based on magnetization, a system and an application thereof. Background technique [0002] Lithographic printing means that during printing, the graphic part and the non-graphic part of the printing plate are almost on the same plane. The plate water application system supplies water to the non-graphic part of the printing plate, and then the ink supply device of the printing system supplies ink to the printing plate. Since the non-graphic part of the printing plate is protected by water, the ink can only be supplied to the printing plate Finally, transfer the ink on the printing plate to the blanket, and then use the pressure between the rubber cylinder and the impression cylinder to transfer the ink on the blanket to the substrate to complete the printing. The water supply device of the printing system uses the principle that ...
