Intaglio printing device and manufacturing method thereof

Abstract

The invention discloses an intaglio printing device, which comprises an intaglio roller and an ink scrapping blade, wherein the ink scrapping blade is matched with the surface of the intaglio roller. An end part of at least one of the intaglio roller and the ink scrapping blade has an end part slope extending along the axial direction of the intaglio roller, thereby leaving a preset distance between the intaglio roller and the ink scrapping blade at the end. A stress applied to the ink scrapping blade is relieved, thereby being difficult to cause a crevasse, obviously reducing the possibility of attaching printing ink to the ink scrapping blade, obviously reducing the possibility of generating printing waste caused by the printing ink thrown onto a printed product, obviously promoting the quality of the printed product and obviously reducing the working strength of an inspector. After the damaged rate of the ink scrapping blade is reduced, the frequency of halting, overhauling and replacing the intaglio printing device is obviously reduced and the printing efficiency is promoted. The use cost of the ink scrapping blade can be lowered by reducing the frequency of replacing the ink scrapping blade, thereby reducing the intaglio printing cost. The invention also provides a manufacturing method for the intaglio printing device.

Description

technical field [0001] The invention relates to the field of gravure printing, in particular to a gravure printing device. In addition, the present invention also relates to a manufacturing method using the above gravure printing equipment. Background technique [0002] As a kind of printing process, gravure printing has the advantages of thick ink layer, bright color, high saturation, high printing plate durability, stable quality of printed products, fast printing speed and other advantages in the field of printing, packaging and graphic publishing. occupies an extremely important position. [0003] Gravure printing, referred to as gravure printing, is one of the four printing methods. Gravure printing is a direct printing method, which directly impresses the ink contained in the gravure pits onto the substrate. composed of the surface. When printing, the ink is filled into the pits, the ink on the surface of the printing plate is scraped off with a squeegee, the print...

AI Technical Summary

Problems solved by technology

[0006] In order to reduce the ink scraping of the doctor blade 11 and improve the printing quality of the printed matter, the existing conventional solution is to replace the new doctor blade 11, but replacing the doctor blade 11 will inevitably cause shutdown, which not only increases the cost of printing, but also increases the cost of printing. Reduce printing efficiency and virtually increase the cost of gravure printing
