Abstract

The invention discloses an on-line color controlling device and an on-line color controlling method for a photogravure press. The method comprises the following steps of: adjusting ink viscosity by a first adjusting device according to a result detected by the first detecting device, after the ink viscosity is confirmed, timely detecting whether the color of a printing image on a material to be printed is within a preset threshold range of color tolerance or not by a spectrophotometer camera, when the color of the printing image exceeds the preset threshold range of the color tolerance, computing color adjustment by a treating device, and controlling a second adjusting device to timely adjust according to the computed color adjustment, so that the real-time detection and the real-time adjustment can be realized, the device and the method are time-saving and labor-saving, the waste can be reduced, and the production cost can be greatly saved, so that the device and the method are very good in application prospect.

Description

technical field [0001] The invention relates to the technical field of printing, in particular to an online color control device and method for a gravure printing machine. Background technique [0002] Gravure printing, referred to as gravure printing, is one of the four printing methods. Gravure printing is a direct printing method such as figure 1 As shown, the graphics and text are directly produced on the printing plate cylinder 10, and the substrate 30 passes between the rubber-coated impression cylinder 20 and the printing plate cylinder 10. The printing plate cylinder 10 has pits, and the printing plate cylinder 10 After inking (in this embodiment, the printing plate cylinder 10 is inked by dipping into the ink tank 40), use the doctor blade 50 to scrape off the ink on the blank part of the printing plate cylinder 10 (then leave the ink in the pit), and then print The plate cylinder 10 is in contact with the impression cylinder 20 , imprinting the ink contained in t...
