Problems solved by technology

[0002] At present, the development of the outer packaging of consumer goods such as cigarette boxes and wine boxes in China is changing with each passing day. The outer packaging materials such as ordinary white cardboard and coated paper have been gradually eliminated. Now more and more medium-sized consumer goods have adopted light silver paper for outer packaging. , laser paper and other high-level new materials, but the surface of these high-level materials is not easy to ink due to the transfer or compounding of the surface, especially when the layered plate has ugly faults during gravure printing, customers have to use offset printing, but offset printing It has the disadvantages of high cost and low efficiency, which seriously affects the economic benefits of customers. Therefore, there is an urgent need in the market for a plate roller for laser paper printing with high printing efficiency, low production cost, and no faults.

Abstract

The invention relates to the technical field of gravure printing rollers, in particular to a printing roller for laser paper printing and a manufacture process thereof. The manufacture process comprises the steps of copper plating, rubber coating, laser carving, etching, decoating and chrome plating. The printing roller comprises a roller body, wherein a non-printing area and a printing area are arranged on the outer surface of the roller body; a copper-coated layer is fixedly connected to the surface of the non-printing area; the laser-carved layer is formed in the surface of the printing area; a chrome-plated layer is fixedly connected to the surfaces of both the copper-coated layer and the laser-carved layer; the laser-carved layer comprises a first carved layer and a second carved layer; the carved screen line number and the carved screen angle of the first carved layer are different from those of the second carved layer. Through the twice-carving process, the gravure-printed faults are dislocated, so that the printing layers are natural and smooth. The manufacture process is simple, the control is convenient and the production efficiency is high.
