A printmaking process that uses two or more blocks, one often as a key or line block in black and others in a single colors in differing tones. Tone blocks were printed in lighter and darker versions of the same color, a characteristic of the 'camaieu' print as resembling engraved cameo stones. Early scholars distinguished two-block from multi-block processes by calling them "camaïeu," that is, the ‘monochrome method,’ distinguishing them from "chiaroscuro woodcuts," Current usage does not make this distinction, and the terms have been used interchangeably in various sources.
