Buffing is a process in which the surface of the skin or hide is mechanically abraded to remove imperfections and create a smooth, uniform surface. This process can also help to enhance the natural grain of the material.
Embossing, on the other hand, involves creating a raised design or pattern on the surface of the skin or hide. This can be done using heat and pressure to press a design into the material, or by using a mold to create a specific pattern. Embossing can add texture and visual interest to the material, as well as provide a decorative element.
