What’s a fine art print?

Fine art prints are not merely duplicates of an original like a mechanically printed poster. Though a painting, drawing or sketch can be used as a starting point, each print is an original work of art, made by the hand of the artist who usually works in tandem with a master printmaker.

Printmaking is arduous work, with most techniques involving a complicated, slow-going series of steps demanding an exacting attention to detail.

Melissa Brown’s linocuts are at Big Medium Gallery.

Many printmaking techniques such as woodcuts, engraving, mezzotint, etching and lithography are centuries old.

Prints are created in sets, referred to as editions. But each print is a unique impression of the same image. Individual impressions vary from one another, sometimes widely.
