Improved method for converting plastic mother film into metal mother matrix

Abstract

The invention relates to an improved method for reproducing a metal master plate by a plastic master film, which is characterized by comprising the following steps: 1) the plastic master film containing information is subjected to film drawing and framing up; 2) the plastic master film surface is subjected to vacuum silver plating; and 3) then the plastic master film is put into electroforming solution for reproducing the metal master plate. Compared with the prior art, the method has the beneficial effects that the mature production technology of vacuum silver plating is adopted to replace the spray silver process in the traditional technology, therefore, the preparation process before the spray silver process in the traditional technology can be simplified, the production efficiency is greatly improved, and the production cost is effectively reduced; furthermore, as the plastic master film does not need to be cooled by distilled cold water of 0 to 50 DEG C before the silver plating, the temperature change of the plastic master film is small when reproducing the metal master plate, and the damage to the silver layer of the plastic master film can be effectively avoided, thus greatly improving the success rate of reproducing the metal master plate to be over 80 percent.

Description

technical field [0001] The invention relates to a method for reproducing a metal master, and more specifically relates to an improved method for reproducing a plastic mother film with information materials into a metal master. Background technique [0002] The existing metal master is usually made by traditional copying method. The traditional plate-making process is purely hand-made, which uses a plastic mother film with information images and is made through the following processes: [0003] 1) Pull the upper frame of the film, take a sufficient area of ​​the plastic mother film and tighten it with tape around the plastic frame to make the plastic mother film smooth; [0004] 2) The plastic mother film is cleaned and degreased, and the plastic mother film is cleaned with a surfactant, and rinsed with deionized water for three minutes; [0005] 3) Enhance the surface tension of the plastic mother film, spray evenly on the surface of the plastic mother film with a surfacta...

AI Technical Summary

Problems solved by technology

[0009] The above-mentioned processes, except for the electroforming method to remake the metal master, are all manually processed through various chemical solvents on the surface of the plastic mother film, and after the completion of the previous process, before entering the next process, they must be used successively. Rinse the plastic mother film with deionized water and distilled water for about three minutes, and the processing steps are very cumbersome

[0010] In addition, the plastic master film needs to be cooled with distilled cold water at 0-50°C before silver spraying, while the plastic master film after silver spraying has to enter the electroforming solution at 30-60°C in the electroforming machine to reproduce the metal master plate. The thermal expansion effect caused by the large temperature change can easily destroy the silver layer on the surface of the plastic mother film, resulting in a significant drop in the success rate of remanufacturing, and the general success rate is only 30%.
