Description
Technical Field
The invention relates to the technical field of packaging paper, in particular to a unit plate, a packaging paper template and a manufacturing method of high-registration-precision packaging paper.
Background
In general, a master plate manufactured by a plate making factory is not suitable for being directly used for production, because in the production process, the surfaces of the master plate and a substrate are possibly scratched due to contact friction, patterns on the surface of the master plate are damaged, defects are formed, one or more devices are caused to fail, and the product yield is reduced due to accumulation of the defects after multiple uses. Therefore, the working plate used for production is a copying method, one or more working plates are copied by using the master plate, and the copied working plate is used during production because the cost of the working plate is lower compared with that of the master plate and the damage to the master plate is small. Even if the pattern defect is caused by the repeated use of the working plate in the production process, a new working plate can be conveniently copied again, and the copying process is generally called a copying process.
The holographic product has high requirement on the apparent quality of a master plate, and can not have macroscopic flaws, and the conventional large-format micro plate making technical scheme comprises the following processes: photoetching unit plate → electroforming unit plate → small plate and large plate (mechanical plate or UV plate) → electroforming large plate → large area working plate. Wherein: the photoetching unit plate is a unit miniature plate for making a plate and containing miniature encryption information; the electroforming unit plate is a nickel plate unit plate containing micro encryption information plated after the photoetching unit plate is subjected to silver spraying and electroforming; the small plate and the large plate are spliced into a large-area plate by a unit plate (namely, a miniature plate), and the plate splicing process is mainly divided into a mechanical process and a UV process; the electroforming large plate is a large-area working plate which is manufactured by electrifying and casting a large-area miniature plate after plate splicing. The technical scheme disclosed by the Chinese invention patent 'a method for manufacturing a holographic master by electroforming imposition' (200910063601.6) is as follows: fixing a plurality of nickel plates with unit holographic patterns on a flat plastic bottom plate by using double-sided adhesive tapes, and then eliminating spliced seams among the nickel plates with the unit holographic patterns by using an electroforming method to manufacture a large-size holographic master plate.
The prior plate making technology is to make a unit micro plate first and then make a large-area micro plate through a plate making process, the whole process flow needs three production processes of unit plate making, electroforming and plate making, and the influence on the apparent quality of a product caused by external environment and human factors is inevitable in the processes of pattern transfer and process conversion.
For example: in the electroforming and copying process, the pattern obtained by copying is slightly shrunk compared with the pattern of the master plate, the more the generation number of the copying is, the larger the deformation degree is, the larger the size difference between the pattern and the master plate is, the influence on the registration accuracy is high, and the uniformity of the size of a final product is not facilitated.
Therefore, in order to ensure that the pattern obtained after the copying is consistent with the size of the final product, the pattern of the master plate is usually made to be slightly larger than the size of the final product when the master plate is made. However, it is difficult to achieve the consistent sizes of the unit plates, so that the patterns on the unit plates are not connected in place when the unit plates are spliced into a large-area plate.
The foregoing description is provided for general background information and is not admitted to be prior art.
