also: Woodblock print (in European usage)
Woodcut is a relief-printing technique: the image is cut into a wooden block, the raised surfaces are inked, and the block is pressed onto paper or fabric. It is the oldest print technique, used in China for textiles and Buddhist texts by the 7th century, and independently taken up in Europe in the 14th century for playing cards, devotional images, and eventually book illustration. The medium imposes its own aesthetic - bold outlines, stark black-and-white contrast, visible cutting marks, and hatching instead of tone - which is exactly why artists from Dürer to Kollwitz chose it for expressive, graphic impact. In Japan the same relief logic produced ukiyo-e; in 20th-century Europe it powered expressionist and protest art. Because the finished print is not the block itself but its impression, woodcut is also a reproducible (multiple) medium.
