Problems solved by technology

[0004] At present, the head of the engraving knife of the electronic engraving machine is in the shape of a square pyramid, and the carved holes are V-shaped. The volume of this V-shaped hole is small, so the ink capacity is small, so that the ink content of the printed product is low. , the color saturation is not enough

Embodiment Construction

[0014] In the present embodiment, the manufacturing method of ultra-fine gravure plate roll comprises the following steps:

[0015] (1) making a version roller body, the cylindrical surface of the prepared version roller body has a layer of copper layer 1;

[0016] In this embodiment, a cylindrical steel pipe is used as the plate roll base 4, and then a layer of copper layer 1 with a uniform thickness is plated on the cylindrical surface of the plate roll base 4 to obtain a plate roll body, wherein the copper layer 1 is the working surface of electronic engraving;

[0017] (2) Make a subpoena file according to the design pattern, and send the subpoena file to the electronic engraving machine;

[0018] (3) The electronic engraving machine forms an engraving control signal according to the subpoena document, drives the movement of the engraving knife and the plate roller body, the engraving knife engraves on the copper layer 1, and the engraving knife forms an engraving groove 3...

Abstract

A manufacture method of a superfine intaglio roller includes the following steps: (1) manufacturing an intaglio roller body, wherein a layer of copper layer is arranged on a cylindrical surface of the manufactured intaglio roller body; (2) manufacturing ticket files according to design patterns and transmitting the ticket files to an electronic carving machine; and (3) leading the electric carving machine to form carving control signals according to the ticket files, driving a carving knife and the intaglio roller body to move, and carving on the copper layer through the carving knife. The manufacture method is characterized in that in the step (3), each time the carving knife carves, a carving groove is formed, and each ink cell is composed of a plurality of carving grooves. The bottom of each ink cell of the intaglio roller manufactured by the method is relatively flat, and the area of the bottom is large, so that the ink cells have large volume ( the volume is improved by 40-60% compared with the ink cells carved in the prior art). The printed pattern is high in ink containing amount, and refined image texts can from in printing conveniently.

Description

technical field [0001] The invention relates to a manufacturing process of a printing plate, in particular to a manufacturing method of an ultra-fine gravure plate roll. Background technique [0002] Gravure printing is a commonly used printing process at present. Its printed products have the advantages of thick ink layer, bright colors, and can truly reproduce the effect of the original manuscript. It can also be printed with relatively environmentally friendly inks such as water-based inks and alcohol-soluble inks, and is widely used. Plastic film, paper, composite materials and other substrates. [0003] The production method of the gravure plate roller is mainly electronic engraving (including ordinary electronic engraving and ultra-fine electronic engraving), which generally includes the following steps: (1) Making the plate roll body: generally using a cylindrical steel pipe as the base of the plate roll, and then The cylindrical surface of the version roller base is...
