Abstract

The invention discloses a metal gravure plate laser manufacturing method and system. The metal gravure plate laser manufacturing method and system have the advantages that the plate grain depth erroris controllable, the large-breadth pattern manufacturing precision is high, and the influence on the service life of a gravure plate substrate in the manufacturing process is small. The method comprises the following main steps of 1, calibrating the corresponding relation between different depths of a single-layer pattern and laser processing parameters; 2, layering a plate grain structure to obtain a single-layer scanning pattern; 3, calibrating the position of a gravure plate substrate and the focus position of an emergent light beam of a laser; 4, planning a track of the single-layer scanning pattern; 5, processing and manufacturing a first layer of pattern; and 6, repeating the step 5 until the processing of the pattern structure is completed.

Description

technical field [0001] The invention relates to a gravure plate manufacturing technology, in particular to a laser manufacturing method and system for a metal gravure plate. Background technique [0002] Gravure printing is a direct printing method. It imprints the ink contained in the pits of the gravure plate directly onto the substrate. The shades of the printed picture are determined by the size and depth of the pits. If the pits If the pit is deeper, it contains more ink, and the ink layer left on the substrate after embossing is thicker; on the contrary, if the pit is shallower, the amount of ink contained is less, and the ink layer left on the substrate after embossing is thicker. The ink layer is thinner. This will form a rough three-dimensional fine structure on the surface of the substrate. The degree of reduction of this structure is determined by the manufacturing quality of the gravure printing plate, and it is also a general anti-counterfeiting method in the p...
