There are many processing methods on the surface of stainless steel, which can be roughly divided into two kinds, one is to make the stainless steel by processing the surface gloss, and the use of gloss contrast pattern art processing; The other is the artistic processing in which color is given in the composition of the pattern. Among them, the use of screen printing method of typical examples of etching processing, spray color processing.

Etching processing method, is in stainless steel surface color with screen printing acid resistant protective film, and then with ferrous chloride etching, the formation of artistic patterns. Spray color method is in the screen printing after the injection of color particles, constitute the surface of pear skin, the formation of artistic patterns.

In recent years, in order to adapt to the diversification of stainless steel use and higher and higher artistic requirements, developed with color “color art” processing method, and has become the mainstream of this field. In endows stainless steel color methods, including the use of screen printing color ink after firing method and chemical coloring method.
