Abstract

The invention discloses a method for manufacturing a gravure roller by an electronic engraving method. The method comprises the following steps: firstly, manufacturing a printing plate substrate and plating copper on a printing plate roller, and forming a plate making copper layer on the surface of the printing plate roller; secondly, plating a chrome layer on the plate making copper layer, and engraving; thirdly, eroding an engraved V-shaped ink cell, so as to deepen and widen the plate making copper layer corresponding to the V-shaped ink cell and enlarge the volume of the ink cell; and fourthly, removing chrome from the eroded printing plate roller; and lastly plating the chrome layer functioning as protection. Compared with the prior art, the gravure roller manufactured by the method has the ink cell with larger volume and larger ink capacity, has good color saturation of printed matters when transfer printing, and has higher printing quality.

Description

technical field [0001] The invention relates to the field of gravure printing, in particular to a method for preparing gravure rolls by electronic engraving. 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. occupy an extremely important position. [0003] From the perspective of application, in foreign countries, gravure printing is mainly used for fine publications such as magazines and product catalogs, packaging printing and printing of securities such as banknotes and stamps, and is also used in special fields such as decorative materials; Printing is mainly used for flexible packaging printing. With the development of domestic gravure printing technology, it has also been widely used in paper packaging, wo...
