Copper electroforming process has been applied to duplicate Koryo Tripitaka (Taejang'kyong), wooden printing block. Thin copper replica printing plates of 1 mm thickness was successfully manufactured from the printing face (54.5${\times}$25.5 cm) of wooden printing plate. Major processes are (1) silicon rubber replication of the master (2) silvering on silicon rubber (3) copper electroforming (4) separation of copper from the silicon mandrel (5) final coloring by brass plating and trimming. This process has various Potential applications in making thin metallic objects such as plaques, statues, bust and hollow metal objects for jewelry.
