- Electrotyping (also galvanoplasty) is a chemical method for forming metal parts that exactly reproduce a model. The method was invented by Moritz von Jacobi in Russia in 1838, and was immediately adopted for applications in printing and several other fields.
Electrotyping is an method of forming metal by Electrolytic deposition. The technique developed with the advent of electricity during the mid 19th century and was used extensively by artists and sculptors to capture minute detail in metal. By the turn of the 20th century, Electrotyping was a well established field and had expanded into the printing industry where it was used to plates for image reproduction.
