Description

Technical Field

[0001] The utility model relates to the technical field of printing equipment, in particular to an inker for an intaglio printing press. Background Art

[0002] In the existing intaglio printing technology, the printing plate is inked by an immersion method. The specific method is as follows: a cylindrical intaglio printing plate is used. Before printing, a certain amount of ink (generally 5 kg to 10 kg) is poured into an ink cartridge. During the rotation of the printing plate along its axis, the surface of the printing plate is immersed in an ink tank to obtain ink, and then a doctor blade is used to scrape off the excess ink on the surface of the printing plate, and then the printing plate is printed on the required material; usually, only about 5 grams of ink is required for printing one square meter, but there is a large amount of ink in the ink cartridge during the existing printing process. When the printing plate rotates and immerses in the ink during printing, a stirring effect will be formed, which is likely to cause a large amount of ink to volatilize, resulting in ink waste and air pollution; at the same time, it is not easy to control the ink supply amount by using the immersion inking method, and a large amount of ink is easily wasted.
