An Intelligent Gravure Printing System

Abstract

The invention discloses an intelligent gravure printing system, which includes a substrate, a roll feeding device, a scraping device, an ink tank, a gravure plate roller, an embossing cylinder, a drying device, a connecting line, a host computer, and a winding device; The gravure roller in the printing device adopts the intelligent gravure roller; the present invention controls the piezoelectric ceramics inside each cell through the computer according to the difference in light and dark levels of the original, so that each cell Meet the depth requirements of different tones, eliminating the steps of plate making; when the printing cylinder is immersed in the ink tank, a vacuum is generated through the deformation of piezoelectric ceramics, so that the ink enters the mesh under the action of atmospheric pressure; when the printing cylinder is in contact with the substrate , and then through the deformation of piezoelectric ceramics to make it flush with the surface of the printing cylinder, the ink in the cell is transferred to the substrate without using any pressure device; it can self-repair, and can also be used for barcode printing, anti-counterfeiting printing and personalization Product printing.

Description

technical field [0001] The invention belongs to the technical field of gravure printing, and relates to an intelligent gravure printing system, in particular to an intelligent gravure printing system which does not require plate making and has variable cell depths. Background technique [0002] As a kind of printing process, gravure printing relies on the depth of the concave surface of the printing plate to express the level of the image. The deeper the concave part of the graphic part, the more ink will be filled in, the thicker the ink layer, and the dark tone will be expressed; If the part is shallow, the amount of ink held is less, the ink layer is thinner, and the performance is high-profile. Due to the different depths of the depressions in the graphic part of the printing plate, the amount of ink filled in the mesh holes is more or less, and the ink layer transferred to the substrate can be thick or thin, so that the shades of the original manuscript can be reproduce...
