Abstract

The invention relates to a manufacturing method of a gravure plate roller with a zinc coating. The manufacturing method comprises the following steps of (1) conducting machining on a steel billet roller to obtain a steel roller; (2) plating the zinc coating on the surface of the steel roller; (3) engraving the image-text part on the zinc coating; and (4) plating a chromium coating on the zinc coating to obtain the gravure plate roller with the zinc coating. Compared with the prior art, the manufacturing method provided by the invention has the advantages that a traditional steel roller surfacenickel coating and copper coating plating process is changed to the zinc coating plating process; the manufacturing process of the gravure plate roller is simplified; the production period of products is shortened; the market response time is accelerated; the production cost of the gravure plate roller is lowered; and the manufacturing method is friendly to environment.

Description

technical field [0001] The invention belongs to the technical field of gravure roll processing and manufacture, and relates to a manufacturing method of a gravure roll containing a galvanized layer. Background technique [0002] Gravure roller printing is a direct printing method. Usually, the entire surface of the plate roller is covered with ink, and then a special scraping mechanism is used to remove the ink on the blank part of the plate roller, so that the ink only remains in the picture and text. In some of the cells, under the action of greater pressure, the ink is transferred to the surface of the substrate to obtain a printed matter. Among them, the graphic part of the plate roller is concave, and the degree of concave is different with the level of the image, and the blank part of the plate roller is convex and at the same height. [0003] The structure of the gravure roll is usually as follows: the inner surface of the basic steel roll is electroplated with a nic...
