Description
Technical Field
The invention relates to the technical field of printing, in particular to a method and a system for protecting water-soluble photosensitive resin domain patterns.
Background
At present, each bank note printing enterprise uses a water-soluble photosensitive resin plate as a line pattern plate in a dry offset printing process; in the gravure process, a water-soluble photosensitive resin plate is used as a color master. The specifications (such as the thickness of the resin layer and the size of the plate surface) of the two water-soluble photosensitive resin plates are different, but the basic structure and the performance are the same, namely the water-soluble photosensitive resin plates are composed of a steel plate base, an adhesive layer and a photosensitive resin layer. The photosensitive resin layer is water-soluble polyamide resin, after exposure to ultraviolet light, the resin in the visible light part is cured to form a raised pattern, and the resin in the invisible light part is removed by washing and dissolving to form a depressed non-pattern part. The water-soluble photosensitive resin plate has good solvent resistance of a resin layer after the plate surface is cured, but can generate swelling deformation or falling-off phenomenon under the long-term action of water. For example, when the outdoor temperature is at a high temperature of 40 ℃, the printing equipment in the closed workshop is relatively at a low temperature, especially the surface of the printing cylinder is made of metal, the surface temperature is low, the printing plate is wrapped on the printing cylinder, the surface temperature of the printing plate is also low, and if outdoor hot air enters the printing workshop (for example, due to the reasons of construction and the like, a door of the printing workshop is opened, the airtightness of the workshop is poor, a temperature control device is not opened, and the like), moisture in the hot air meets the printing equipment and the printing plate at the low temperature, and condensed water is easily generated. The condensed water continuously acts on the pattern of the water-soluble photosensitive resin printing plate, and the pattern is deformed and even falls off. Because the variety of the produced paper money is relatively single, the production quantity of the paper money of a certain variety is large, the continuous production time is long, the service life of the water-soluble photosensitive resin plate on the printing machine is long, generally more than 6 months, and therefore, the effective protection measures for the water-soluble photosensitive resin plate stored in a storehouse or installed on the printing machine are very important. Otherwise, the pattern of the printing plate is likely to deform or fall off, so that the printing plate is scrapped and huge waste is caused.
In the current water-soluble photosensitive resin version protection process, when the water-soluble photosensitive resin version does not use, all carry out the protection of water-soluble photosensitive resin version through the mode that adopts to cover dustproof cloth for can not effectually prevent the harm of comdenstion water to water-soluble photosensitive resin version, reduced the life of water-soluble photosensitive resin version.
