What is the difference between standard soft enamel, cloisonne and die struck

Soft Enamel

After a custom coin is electroplated in your choice of metal plating, enamel paint is added to the recessed areas of your custom coin. The raised metal lines within the design are used to keep the colors from bleeding into one another. Once all the colors are added to these recessed areas, the coins are heat treated to get the paint to dry quickly and to strengthen it against chipping or other wear and tear.

Soft Enamel

Cloisonné (Hard Enamel)

Just like soft enamel, enamel paint is added to the recessed areas of the custom coin, but unlike with soft enamel, the enamel paint is added until it reaches the top of the metal lines. Each color is heat treated before applying the next color. Metal plating occurs after the color filling, so when the coins enter the polishing process, the final result is a smooth flat surface.

Die Struck

Die striking involves using a freshly made coin mold to stamp artwork into brass. Unlike soft and hard enamel, after the metal plating process, no paint is added to the custom coin.
