Glossary

• Edition

  All copies of a book, print, portfolio, sculpture, etc., issued or produced at one time or from a single set of type. Printed works can be made in an edition of between one and many thousands of copies. With most printing techniques the plate or screen will become worn if very many prints are made, so to maintain quality (and exclusivity) editions of original prints are usually kept below one hundred copies and normally average between thirty and fifty copies. Prints made up of several different plates can be extremely complicated and time-consuming to edition, so in these cases editions are kept low for practical reasons. Sculptural editions are a set of cast sculptures taken from the same mould or master. These editions are usually much lower, consisting of no more than six casts. Though each cast in an edition might have a lower value than a unique piece, it may be a more effective way of offsetting costs of an expensive process such as bronze casting.

• Linocut

  A relief print, made by cutting into the surface of a piece of lino with a simple gouge, knife or engraver’s tool. The surface of the lino is then inked and printed: this can be done by passing it through a press, though it can also be done manually by rubbing the paper onto the lino with the back of a wooden spoon or similar implement.

• Medium

  Refers to either the material used to create a work of art, craft or design, i.e. oil, bronze, earthenware, silk; or the technique employed i.e. collage, etching, carving. In painting the medium refers to the binder for the pigment, e.g. oil, egg, acrylic dispersion. The plural form is media.

• Portfolio

  A set of pictures (as drawings, photographs or prints) either bound in book form or loose in a folder. These can be by the same artist or individual works by a selection of artists. The term also refers to the folder which holds the set.
