Description

Technical Field

[0001] The invention relates to a rotary milling device, in particular to a lifting controllable rotary milling device for a printing plate of an offset printing machine. Background Art

[0002] Printing plates are used to transfer ink to the carrier of printed images on the substrate. Printing plates can be divided into four categories: relief, gravure, planographic and stencil. Polyvinyl alcohol plano-gravure is specially used for positive plate making. It uses zinc plate or aluminum plate as the plate base, and ammonium dichromate and polyvinyl alcohol as the photosensitive film. It is a ready-to-coat photosensitive plate and cannot be stored. Multi-layer metal plano-gravure uses oleophilic copper as the base of the image part and hydrophilic chromium or nickel as the base of the blank part. It uses copper plate or aluminum plate as the plate base, and then plates chromium or nickel after copper plating, and then uses the positive plate making method to make the printing plate. It is a ready-to-coat photosensitive plate and cannot be stored. Diazo resin photosensitive plate is a synthetic photosensitive liquid of diazonium salt and phenolic resin, which is coated on an aluminum plate that has been electrolyzed and anodized.
