What’s the difference between a monotype and a monoprint?
Although these two terms are used interchangeably, there is a big difference between one and the other.
A monotype is a single printed image which does not have any form of matrix. A monoprint has some form of basic matrix. When making monotypes, the artist works on a clean and unetched plate. For monoprints there is always a pattern or part of an image which is repeated in each print. Artists often use etched plates or some kind of pattern such as lace, leaves, or fabric to add texture.

What is a matrix? In printmaking, the matrix is the plate or block used to hold the image (woodblock, linoleum, plexiglass, zinc or copper plate, etc).
