| 7. | In this use the form is typically waterproofed plaster, which remains as a core after electrotyping.
|
| 8. | In 1838, he discovered galvanoplastics, or electrotyping, a method of making printing plates by electroplating.
|
| 9. | Electrotyping was also used to produce entire printing plates directly from the formes composed from movable type and illustrations.
