Intelligent intaglio printing system

Abstract

The invention discloses an intelligent intaglio printing system which comprises a printing stock, a conveying and winding device, an ink scraping device, an ink tank, an intaglio printing roll, an impression cylinder, a drying device, a connection line, an upper computer and a winding device. The intelligent intaglio printing roll is adopted in the intaglio printing roll in a printing device. According to the intelligent intaglio printing system, according to the difference of the shade of grey of an original manuscript, piezoelectric ceramics in all ink cells are controlled through the computer to be deformed, so that the depth requirement of different color tones of all the ink cells can be met, and the plate making step is omitted; when the printing roll is soaked with the ink tank, vacuum is generated through deformation of the piezoelectric ceramics, and ink enters the ink cells under the atmospheric pressure; when the printing roll makes contact with the printing stock, the piezoelectric ceramics are deformed to make the printing stock be flush with the surface of the printing roll, the ink in the ink cells is transferred onto the printing stock, and no pressure device is needed; and self repairing is achieved, and the intelligent intaglio printing system can be used for bar code printing, anti-fake printing and individualized 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 reprodu...
