Patented in 1842, the glyphographic plate was made by covering copper with a thick wax resist and drawing through the wax to expose parts of the metal. The plate was then electroplated creating a metal relief line, similar to the etched metal relief plates of William Blake but much less detailed or elegant. The relief plate can then be letterpress printed along with a caption or other text.
