Gravure wiring printing machine and printing method

Abstract

The invention provides a gravure wiring printing machine (1) and a printing method thereof. The gravure wiring printing machine (1) comprises a paper-feeding mechanism (2), a paper-collecting mechanism (3), a plate cylinder (4) and an impression cylinder (5) which are used for gravure printing. The gravure wiring printing machine (1) further comprises a gravure ink-transferring system. The gravure ink-transferring system is provided with a color-collecting cylinder (6) and represents a plurality of colors in one plate. The color-collecting cylinder (6) is used for converging printing ink in different colors two or more single-color cylinders (7a, 7b, 7c) and then transferring the printing ink to the plate cylinder (4), so that at least one line in a pattern on the plate cylinder is filled with two or more kinds of gravure printing ink in different colors. The gravure wiring printing machine (1) further comprises an ink-scraping system or a plate-wiping system used for scraping off or wiping off unnecessary printing ink in portions without images and texts. The impression cylinder (5) and the plate cylinder (4) with the unnecessary printing ink being scrapped off or wiped off can be operated in a matched mode to complete the gravure wiring printing process.

Description

technical field [0001] The invention belongs to the technical field of printing, and in particular relates to a photogravure wiring printing machine and a printing method. Background technique [0002] Gravure printing equipment is divided into engraving gravure printing equipment and photogravure printing equipment. The gravure printing process is divided into engraving gravure printing process and photo gravure printing process. The two are quite different. [0003] The imprint (ink) of the printed matter obtained by the engraving gravure printing machine and printing technology is protruding from the surface of the paper, and it has obvious unevenness when touched by hand; the ink color of the printed matter has distinct layers and a strong three-dimensional effect. [0004] The imprint (ink) of the printed matter obtained by the gravure printing machine and printing technology is flat, and there is no uneven feeling when touching it by hand, and there is no clear layer...

AI Technical Summary

Problems solved by technology

The above wiring printing equipment and printing method can be summarized as engraving gravure wiring printing equipment and printing method, offset wiring printing equipment and printing method, number wiring printing equipment and printing method, screen plate (stencil) wiring printing equipment and printing method, etc. Moreover, these printing equipment are widely used in banknote printing in various countries, but none of them is a photogravure wiring printing equipment and printing method.
