zincography
The printmaking technique of zincography is closely related to lithography, but in place of the cumbersome, costly lithographic stone, printmakers work on a zinc plate.
The use of tusche, a lithographic wash, often produced a distinct, grainy texture as a result of the oxidation of the zinc plate in the presence of water. This effect, known as peau de crapaud (toad skin), distinguishes a zincograph from the more common lithograph.

Zincography in Brittany
The medium of zincography was favored by Paul Gauguin, Emile Bernard, and others working near the rural village of Pont-Aven in the late 1880s and early 1890s.
Because of the lack of professional printmaking facilities in Brittany, zincography provided a convenient and affordable alternative to traditional lithography.
Additionally, the unique graininess of the zincographic print suited the rough, primitive aesthetic extolled by the School of Pont-Aven.

Experimental techniques
The artist Emile Bernard experimented intensely with printmaking, combining a variety of complicated techniques.
It is believed that for his religious imagery, he first carved his designs into a woodblock and then transferred the image to a zinc plate prior to printing.
This combination allowed Bernard the flexibility to make changes on the zincographic plate while still retaining the Medieval aesthetic of the woodcut.
