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.
