Etching is the technique of removing material by chemical reaction or physical impact. Usually referred to as photochemical etching, also known as photochemical etching, refers to the removal of the protective film from the area to be etched through the exposure of the plate, development, and contact with a chemical solution during etching to achieve the effect of dissolution and corrosion, resulting in the formation of a concave-convex or hollowing out of the shape of the effect.
Laser Biting uses a high energy density laser to react with the surface of the steel to create a snake skin/etched/pearly or other form of texture.
