Photo etched soft enamel Pins are made from a thinner metal plate that is suitable for etching, common material is brass. For photo etched, the color pigments used are same as the pins in soft enamel . Unlike soft enamel pin, your design is photographically negative on a film and put onto the surface of the metal. Then they will go through the machine and your design will “imprinted” on the metal by chemical reaction with acid liquid. Colors are then filled by hand one by one using syringes. Then, it will baked in oven and cut out the desired shape after baked. It is also not resistant to scratch and high temperature. We could add epoxy layer for further protection. Any color in Pantone ® chart is available.
