Monotype:
A print, which is first made by painting an image on a plate(usually metal, plastic, or glass). At this point it is a painting. But, it is then transferred to paper by placing paper over the plate and either by passing it through an intaglio press, or by rubbing the back of the paper against the plate.

The typical question is "Why go through the trouble of changing it from a painting to a print?" The answer is that the transfer often produces effects that are unique, and welcomed by the artist.  The piece is, at once, a painting and a print.  It is still a one of a kind original.
