　　With the development and continuous progress of society, metal signs are increasingly used in various fields of modern society, especially in the fields of electronic products, household appliances, machinery, and civil products. The popularity is mainly due to the unique etching method used in the production process of metal signs.

　　So, what is the etching method for metal signage?

　　1. Provide substrate and perform surface treatment on the substrate;

　　2. Coating photosensitive materials on the front and back of the surface treated substrate;

　　3. Expose the front and back of the coated substrate;

　　4. Developing exposed substrates

　　5. Etching the front side of the substrate with a transfer film on the back side;

　　6. Apply the transfer film to the front of the etched substrate, and apply the transfer film to the back of the developed substrate;

　　7. Remove the film from the back of the substrate coated with the transfer film;

　　8. Etching the back of the substrate after detachment;

　　9. Remove the film from the front of the substrate coated with the transfer film.
