Process flow: Exposure method: engineering according to the graphic out of the material size - material preparation - material cleaning - drying → film or coating → drying → exposure → development → drying - etching → film removal →OK screen printing method: opening → cleaning sheet (stainless steel and other metal materials)→ screen printing → etching → film removal →OK
