Printing roller for laser paper printing and manufacture process thereof

Abstract

The invention relates to the technical field of gravure plate rolls, in particular to a plate roll for laser paper printing and its manufacturing process. The manufacturing process of the present invention includes steps of copper plating, encapsulation, laser engraving, corrosion, degumming, and chrome plating. The invented version roller includes a roller body, the surface of the roller body is provided with a non-printing area and a printing area, the surface of the non-printing area is fixedly connected with a copper plating layer, and the surface of the printing area is provided with a laser engraving layer, and the surface of the copper plating layer and the laser engraving layer are fixed The chrome-plated layer is connected, and the laser engraving layer includes a first engraving layer and a second engraving layer. The number of engraving screen lines and engraving screen angles of the first engraving layer are different from those of the second engraving layer. The present invention can displace the fault position after gravure printing by adopting the manufacturing process of two engravings, so as to achieve natural and flat printing levels. The invention has the advantages of simple manufacturing process, convenient control and high production efficiency.

[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.
