Embodiment 1

[0011] Embodiment 1, this embodiment is a laser gravure printing cylinder of a gravure printing machine, that is, a manufacturing method of a laser gravure printing roller. It includes the following steps: production of printing plate base, copper plating of printing plate base, surface treatment of printing plate after copper plating, laser image file production, gluing of printing plate, laser engraving of printing plate, development of printing plate, printing plate Corrosion, cleaning of printing plates, chrome plating of printing plates. Among them, the production of the printing plate substrate, the copper plating of the printing plate substrate, and the surface treatment of the printing plate after copper plating can also be called the hardware processing of the printing plate, and the laser image file production can be called software production, and the hardware processing and software production can be carried out simultaneously. . The specific process is:

Abstract

The invention discloses a method for producing a high-definition laser gravure plate roller, which comprises the steps of producing a printing plate body, plating copper on the printing plate body, processing the surface of a printing plate after plating copper, producing a laser image file, coating glue on the printing plate, carrying out laser engraving on the printing plate, developing the printing plate, corroding the printing plate, washing the printing plate and plating chromium on the printing plate. The method is characterized in that in the step of producing the laser image file, an original image file is thinned by 20 to 9 micrometers, then the edge of the image file is wrapped with 100 percent of site side lines by 10 to 40 micrometers, and the image file in the side lines is subjected to net suspension. The problem that the printing effect of a glyphographic plate and a common laser plate is affected due to sawteeth at the edge of the image file is solved.

Description

technical field [0001] The invention relates to the field of printing machinery, especially the technical field of gravure printing, in particular to a method for manufacturing a gravure printing roller in a high-definition laser gravure printing machine. Background technique [0002] At present, gravure printing is one of the methods of printing technology. Its printing products have the advantages of thick ink layer, bright and bright color, can truly reproduce the effect of the original manuscript, and strong comprehensive processing ability. In addition, it can use water-based ink and alcohol-soluble ink. , in line with the requirements of green printing, and can be widely used in film, composite materials, paper and other substrates, so it occupies an important position in the printing field. [0003] From the perspective of application, gravure printing is mainly used for fine publications such as magazines and product catalogs, packaging printing and securities printi...
