Xylography

Woodcut is a relief printing technique in printmaking. An artist carves an image into the surface of a block of wood—typically with gouges—leaving the printing parts level with the surface while removing the non-printing parts. Areas that the artist cuts away carry no ink, while characters or images at surface level carry the ink to produce the print. The block is cut along the wood grain (unlike wood engraving, where the block is cut in the end-grain). The surface is covered with ink by rolling over the surface with an ink-covered roller (brayer), leaving ink upon the flat surface but not in the non-printing areas.

Multiple colors can be printed by keying the paper to a frame around the woodblocks (using a different block for each color). The art of carving the woodcut can be called "xylography", but this is rarely used in English for images alone, although that and "xylographic" are used in connection with block books, which are small books containing text and images in the same block. Single-leaf woodcut is a term for a woodcut presented as a single image or print, as opposed to a book illustration.

In both Europe and the Far East, traditionally the artist only designed the woodcut, and the block-carving was left to specialist craftsmen, called block-cutters, or Formschneider in Germany, some of whom became well known in their own right. Among these the best known are the 16th century Hieronymus Andreae (who also used "Formschneider" as his surname), Hans Lützelburger and Jost de Negker, all of whom ran workshops and also operated as printers and publishers. The formschneider in turn handed the block on to specialist printers. There were further specialists who made the blank blocks.

This is why woodcuts are sometimes described by museums or books as "designed by" rather than "by" an artist; but most authorities do not use this distinction. The division of labour had the advantage that a trained artist could adapt to the medium relatively easily, without needing to learn the use of woodworking tools.
