Production method of metal etching handicraft picture

Abstract

The invention discloses a production method of a metal etching handicraft picture. The production method comprises the following steps of: exposing a black and white film on a substrate coated with metal photosensitive ink, performing developing treatment, cleaning, etching and re-cleaning in sequence, performing drying, wire drawing treatment and sealing, and storing a finished product. The production method has the advantages that an etching effect is good, especially for the handicraft picture with fine etching lines, as a side protective agent is added in etching liquid, grain marks are clear and complete when the handicraft picture is etched, the phenomenon that the grain marks are unclear caused by side corrosion cannot occur, a V-shaped structure is formed at the bottom of patterns in etching, the patterns and texts which are etched in the substrate show a stereo effect, especially the texts are etched, the stereo effect is good, and the patterns and fonts cannot discolor or deform so as to be convenient to keep for a long time. The etching method disclosed by the invention can be used for ensuring an attractive effect of the product, and is high in etching efficiency which is dozens of times that of a mechanical engraving machine, so that the working efficiency is greatly improved. The production method can be widely applied in multiple industries.

Description

technical field [0001] The invention relates to a metal etching process, in particular to a method for manufacturing a metal etching process painting. Background technique [0002] Metal etching is to cover the parts that need to be protected on the metal substrate (mainly copper plate, some zinc plate) by screen printing or screen printing, and then chemically or electrochemically corrode the unnecessary parts, and finally Removing the protective film to obtain metal products with patterns or fonts is a processing method, which is a key step in the production of three-dimensional signs, metal crafts, metal prints, seals and other products. However, the products obtained by the traditional metal corrosion process will have serious side corrosion phenomenon. The deeper the corrosion pattern is, the more serious the side corrosion phenomenon will be. Severe side corrosion will cause the product precision to drop or even the product to be scrapped. At the same time, the depth ...

Problems solved by technology

However, the products obtained by the traditional metal corrosion process will have serious side corrosion phenomenon. The deeper the corrosion pattern is, the more serious the side corrosion phenomenon will be. Severe side corrosion will cause the product precision to drop or even the product to be scrapped

At the same time, the depth of the pattern processed by the traditional etching process is generally only 0.2-0.3mm. In addition to the side corrosion of the product, the bottom of the etched pattern can only be flat

As a kind of craft painting, some patterns will be very fine and dense, and the side corrosion phenomenon will lead to poor viewing effect of the painting
