The woodcut is the oldest known graphic technique. The Chinese were cutting images into wooden blocks over 2000 years ago. Traditionally, a woodcut is made using wood from a fruit tree such as an apple or pear tree, which has a nice fine grain, making it robust yet soft enough to carve. All the wood apart from the image itself is cut away using gouges. The woodcut is a relief printing technique, whereby only the raised image left after the rest of the wood is cut away transfers the ink to the paper. Once the block of wood has been prepared, the artist uses a roller to apply ink to its surface. A sheet of paper is then laid on the block, and the ink pressed into the paper. The woodcutting technique differs from wood engraving in the sense that in the latter the image is cut along the grain of the wood, allowing more detailing.
Unusually, Escher printed all of his woodcuts himself. He never used machines and had no assistants to help him. The 650 prints of Day and Night (1938) were therefore all made by Escher’s own hand. Escher generally used thin handmade paper, such as Japon. This very thin Dutch-manufactured paper absorbs ink much more readily than thicker paper. Escher would first dampen the paper to loosen the fibres, which made it even more absorbent. Less pressure would then be needed to transfer the ink from the block to the paper.
Since the print is a mirror-image of the woodcut itself, Escher had to cut his design in mirror-image too. He therefore had to turn everything around in his head, including any letters and numbers. He would often include his monogram, for example, and he also cut the date on which the work was made into the block.
The woodcut is the oldest known graphic technique. The Chinese were cutting images into wooden blocks over 2000 years ago. Initially, the image would be printed on fabric. Printing on paper was introduced later. Woodcuts were first made in Europe in the Middle Ages. Early highpoints of European woodcut printing include the work of Albrecht Dürer, Hans Holbein the Younger and Lucas van Leyden, and the chiaroscuro woodcuts created in the Renaissance. In chiaroscuro woodcuts, first introduced in Italy around 1516, an image on one or two blocks is printed using different coloured inks. Focusing on the light (chiaro) or shade (scuro) creates an illusion of depth due to the tonal contrasts.
Contemporary artists are also interested in wooden blocks as a medium for printing images. They include conceptual artists such as Chuck Close, who died in 2021. After his early success with painting, he started using printing techniques like mezzotint, linoleum cuts and woodcuts. Close based his prints on photographs which he would divide into individual, fairly abstract images that he would reproduce on wooden blocks and then print to recreate the whole image. The individual elements remain visible from close by, but merge into a new image when viewed from a distance.
