Description

Technical Field

[0001] The present application relates to the field of metal painting production, and in particular to a metal painting laser sandblasting device. Background Art

[0002] Metal painting is an art form that uses metal materials as painting media. Different from traditional painting media (such as paper and canvas), metal painting uses metal sheets, iron sheets, aluminum plates and other metal materials as the basis of the picture. Artists can create rich and diverse textures and patterns on the metal surface through etching, sandblasting, engraving, branding and other processes.

[0003] Metal paintings are usually original works designed and produced by art festivals or designers, which may contain a lot of intellectual property value. Anti-counterfeiting measures can effectively protect intellectual property rights and prevent piracy, infringement and unauthorized copying. Ordinary anti-counterfeiting methods are usually displayed on product packaging or labels. The visual effect is relatively simple, and the visual experience and texture of the artwork are limited. The surface after laser sandblasting presents a rougher texture, with a certain light reflection and refraction effect, which increases the visual layering and texture.

[0004] With respect to the above-mentioned related technologies, the applicant believes that using laser sandblasting to make anti-counterfeiting marks on metal paintings can help improve the visual experience and texture of metal paintings. Utility Model Content
