[0002] Label embossing is the process of artistically processing the printed material surface by making the printed material substrate undergo plastic deformation under a certain pressure using a concave and convex mold. Various convex images and patterns are pressed out on the surface of the printed material substrate. Hot stamping, also known as thermal transfer printing technology, is the process of transferring the aluminum layer in electroplated aluminum to the surface of the substrate to form a special metallic effect. By embossing the label with hot stamping, the visual appeal and quality of the product are enhanced.
