Woodcuts are identical to linocuts in process, but have a unique appearance because the inked surface of the block often picks up the texture of the wood grain, which in turn transfers to the printed image. Woodcuts were some of the first kinds of prints made in ninth-century China, and the practice was later adopted by the Europeans. In the seventeenth and eighteenth centuries, Japanese artists using woodcut techniques reached an exceptional level of artistic achievement through a style called ukiyo-e. Multiple colors can be achieved by creating a separate block for each color, however around 1915, artists in the Provincetown art colony developed white-line woodcuts – a process which allowed for many colors to be printed on one block. By cutting a groove between each colored surface in the composition, the artists were able to apply ink only to the raised areas while the groove, which does not receive ink, prints as a blank or "white" line which separates each area of color.
