Woodblock printing is a technique for printing text, images or patterns used widely throughout East Asia and originating in China in antiquity as a method of printing on textilesand later paper. As a method of printing on cloth, the earliest surviving examples from China date to before 220 AD, and woodblock printing remained the most common East Asian method of printing books and other texts, as well as images, until the 19th century. Ukiyo-e is the best known type of Japanese woodblock art print. Most European uses of the technique for printing images on paper are covered by the art term woodcut, except for the block-books produced mainly in the 15th century.

The wood block is carefully prepared as a relief pattern, which means the areas to show 'white' are cut away with a knife, chisel, or sandpaper leaving the characters or image to show in 'black' at the original surface level. The block was cut along the grain of the wood. It is necessary only to ink the block and bring it into firm and even contact with the paper or cloth to achieve an acceptable print. The content would of course print "in reverse" or mirror-image, a further complication when text was involved. The art of carving the woodcut is technically known as xylography, though the term is rarely used in English.

For colour printing, multiple blocks are used, each for one colour, although overprinting two colours may produce further colours on the print. Multiple colours can be printed by keying the paper to a frame around the woodblocks.
