Woodcut - Colour

Colour

Coloured woodcuts first appeared in ancient China. The oldest known are three Buddhist images dating to the 10th century. European woodcut prints with coloured blocks were invented in Germany in 1508 and are known as chiaroscuro woodcuts (see below). However, colour did not become the norm, as it did in Japan, in the ukiyo-e and other forms.

In Europe and Japan, colour woodcuts were normally only used for prints rather than book illustrations. In China, where the individual print did not develop until the nineteenth century, the reverse is true, and early colour woodcuts mostly occur in luxury books about art, especially the more prestigious medium of painting. The first known example is a book on ink-cakes printed in 1606, and colour technique reached its height in books on painting published in the seventeenth century. Notable examples are the Treatise on the Paintings and Writings of the Ten Bamboo Studio of 1633, and the Mustard Seed Garden Painting Manual published in 1679 and 1701.

In Japan colour technique, called nishiki-e in its fully developed form, spread more widely, and was used for prints, from the 1760s on. Text was nearly always monochrome, as were images in books, but the growth of the popularity of ukiyo-e brought with it demand for ever increasing numbers of colors and complexity of techniques. By the nineteenth century most artists worked in colour. The stages of this development were:

• Sumizuri-e (墨摺り絵, "ink printed pictures") - monochrome printing using only black ink
• Benizuri-e (紅摺り絵, "crimson printed pictures") - red ink details or highlights added by hand after the printing process；green was sometimes used as well
• Tan-e (丹絵) - orange highlights using a red pigment called tan
• Aizuri-e (藍摺り絵, "indigo printed pictures"), Murasaki-e (紫絵, "purple pictures"), and other styles in which a single color would be used in addition to, or instead of, black ink
• Urushi-e (漆絵) - a method in which glue was used to thicken the ink, emboldening the image; gold, mica and other substances were often used to enhance the image further. Urushi-e can also refer to paintings using lacquer instead of paint; lacquer was very rarely if ever used on prints.
• Nishiki-e (錦絵, "brocade pictures") - a method in which multiple blocks were used for separate portions of the image, allowing a number of colors to be utilized to achieve incredibly complex and detailed images; a separate block would be carved to apply only to the portion of the image designated for a single color. Registration marks called kentō (見当) were used to ensure correspondence between the application of each block.

In the 19th century a number of different methods of colour printing using woodcut (technically Chromoxylography) were developed in Europe. George Baxter patented in 1835 a method using an intaglio line plate (or occasionally a lithograph), printed in black or a dark colour, and then overprinted with up to twenty different colours from woodblocks. Edmund Evans used relief and wood throughout, with up to eleven different colours, and latterly specialized in illustrations for children's books, using fewer blocks but overprinting non-solid areas of colour to achieve blended colours. Artists such as Randolph Caldecott, Walter Crane and Kate Greenaway were able to draw influence from the Japanese prints now available and fashionable in Europe to create a suitable style, with flat areas of colour.

In the 20th century, Ernst Ludwig Kirchner of the Die Brücke group developed a process of producing colored woodcut prints using a single block applying different colors to the block with a brush à la poupée and then printing (halfway between a woodcut and a monotype). A remarkable example of this technique is the 1915 Portrait of Otto Müller woodcut print from the collection of the British Museum.
