An impression is printed from a reprintable block, such as an etched plate or woodblock, but in such a way that only one of its kind exists, for example by incorporating unique hand-colouring or collage.
The term can also refer to etchings which are inked and wiped in an expressive, not precisely repeatable manner; to prints made from a variety of printing elements that change from one impression to the next; or to prints that are painted or otherwise reworked by hand either before or after printing.
The beauty of monoprinting lies in its spontaneity and its allowance for combinations of printmaking, painting and drawing media.
