Stainless steel screen printing is often used in our daily production. It can be roughly divided into two types, one is to process the stainless steel to give it surface gloss, and use the gloss contrast to form patterns to perform artistic processing; the other is to provide color in the composition of patterns. Among them, typical examples using the screen printing method include etching processing and inkjet processing.
The etching process of stainless steel products is: stainless steel products → silk screen → etching → alkali treatment → oxidation coloring → finished products.

without pigments and fuels. Stainless steel is immersed in a heated concentrated chromium sulfate solution for chemical coloring, which is characterized by good food resistance. The ink used in this processing method must have very strong acid resistance. Generally, UV curing inks with special properties that are compatible with the processing process are used.
In recent years, in order to adapt to the diversification of stainless steel applications and the increasingly high artistic requirements, a "color art" processing method with colors has been developed and has become the mainstream in this field. Methods for imparting color to stainless steel include a method of using a screen printing color ink and firing, and a chemical coloring method.
