Since ancient times, seal script has been used for printing, hence the name seal cutting. The knowledge of seal cutting is called seal cutting. Seal cutting is independent of painting and calligraphy, and has its own style, but it is closely related to the art of painting and calligraphy. The font writing before seal cutting and the seal script works after seal cutting are all manifestations of calligraphy. The process of seal cutting is an art combining calligraphy, painting and sculpture.
