Impression of two or more woodblocks, generally one line block and various tone blocks, which are printed on top of each other. The result is a colour print, usually in various shades of a single colour, which may look like a pen-and-wash drawing or an oil sketch. Some are printed on cloth, or paper textured like cloth, which adds to their painterly effect. As such, and because of their monumental impact, they were ideal for hanging on a wall as substitutes for oil.
