Xylography

Multiple colours can be printed by keying the paper to a frame around the woodblocks (using a different block for each colour). The art of carving the woodcut can be called xylography, but this is rarely used in English for images alone, although that term and xylographic are used in connection with block books, which are small books containing text and images in the same block. They became popular in Europe during the latter half of the 15th century. A single-sheet woodcut is a woodcut presented as a single stand alone image or print, as opposed to a book illustration.
