Monotype

The term monotype refers not only to a unique print (after which the plate is destroyed) but also to prints that, through different inks or other changes, are unique or differ from the main edition — as when the artist tests the plate with a new colour or on an unusual support. They are made on glass, a smooth metal plate or stone with greasy media such as paint or oil-based printing ink, so each prepared plate yields only one good print. The image is then pressed onto absorbent paper by hand or with an etching press. The pigment left on the plate is usually not enough for another print unless it is inked again, so each impression differs from the previous one. Because of this authenticity, monotypes cannot be considered a technique of multiple reproduction; they are prints on paper catalogued within printmaking.
