French sculptor Pierre Roche was born in 1855. Roche invented the technique of the gypsographic print at the beginning of the nineteenth century. A gypsographic print is made according to a process known by the same name. The point of departure is a plaster engraving made from a bas-relief mould. When the plaster engraving is inked, the ink is caught in the relief areas. Next, the dampened paper is printed by hand and catches the ink on the relief areas and is, at the same time, pushed into the hollows of the plaster plate. This type of print looks somewhat like a bas-relief with some color. Roche died in 1922.
