Problems solved by technology

[0016] However, the plate-making method of the resin plate is time-consuming and laborious. Another serious defect is that the waste liquid after washing the plate will affect human health, that is, the environmental protection of the production environment.
At the same time, the dots of the flexographic photosensitive resin plate below 5% are easy to expand during the printing process, which affects the printing accuracy

Abstract

The invention provides a rubber flexographic engraving plate and a manufacturing method thereof. The rubber flexographic engraving plate is of a three-layer structure and comprises an engraving layer,a bonding layer and a lining supporting layer which are sequentially arranged from top to bottom, the rubber flexographic engraving plate can be subjected to laser direct engraving forming, the flexible resin plate manufacturing manner is changed, in the rubber flexographic engraving plate manufacturing process, industrial hazardous waste cannot be generated, and meanwhile, the reappearing property of lattice points below 5% in the printing process can be improved.

Description

technical field [0001] The present invention belongs to the technical field of printing, and more specifically belongs to the technical field of flexographic engraving plate processing. It relates to a rubber flexo engraving plate and a manufacturing method thereof, and more particularly relates to a rubber flexo engraving plate which can be directly engraved by laser. It can replace flexographic resin plates. Background technique [0002] At present, the printing plates used in domestic flexographic printing generally use resin plates made of photosensitive resin materials, and their structure is from top to bottom black film layer, photosensitive resin layer and base layer. The plate-making method of this kind of printing plate is to form the graphic part by light-curing photosensitive resin, and then use chemical solvent to etch and wash off the excess resin, and then dry and debond sequentially. [0003] CN108349286A discloses an offset printing plate, wherein the off...
