The process of washing ink

The color change of the ink wash is often seen during the offset printing process, and the entire ink system of the offset press needs to be cleaned and replaced with a new ink. The ink-washing device scraper is composed of a rubber knife, an ink receiving slot, and a tight adjusting screw.

The process of washing ink: Pour gasoline and car wash water on the roller, install the wiper in the position of the washing ink tank, and tighten the adjusting screw so that the rubber blade is at an angle of 40° to the surface of the ink roller corresponding to the offset printing machine. Contact, longitudinal and lateral movements of the ink roller, the old ink and gasoline on the ink system are continuously scraped through the rubber blade into the ink receiver.
