Wood-block printing is a relief method. This means that the uncut surface of the block will print and the cut-away areas will not.
To make a print, the artist cuts a piece of softwood, such as pine or fir, to a desired size. In order to see the area that will be printed, the artist may first paint the block of wood with india ink. The contrast between the color of the ink and the color of the bare wood shows the artist which areas will print and which will not.
Some artists trace a drawing or draw directly on the wood with chalk, while others cut directly, without following a sketch. In either case, the artist cuts the design with a knife and a tool called a gouge. Then tacky ink is applied to the surface of the block with a roller. Next the artist carefully places a piece of very absorbent paper—such as Japanese rice or mulberry paper—on the inked block. When the paper is rubbed with a hard, smooth instrument, the inked image on the block is transferred to the paper. The artist then inks the block again and makes any number of prints. To make a print of many colors, the artist follows the same steps; but a different block is needed for each color.
Traditionally, woodcut prints have been divided into two types: black-line cuts and white-line cuts. In a black-line cut, the surface areas that print form the main shapes of the design. In a white-line cut—the more popular form—the shapes of the design are cut away. Therefore, the areas that print are actually the background of the design.
