Various colors appear due to the interference effect of light film. This is the basic principle of colorful marking of stainless steel. In short, under the action of laser, the surface of stainless steel produces laser thermal effect. With different energy, different colors appear on the exterior of stainless steel.

The traditional colorful preparation methods of stainless steel such as chemical coloring and electrochemical coloring used in the past have high energy consumption, high pollution, and difficult to complete precise coloring.
