From series Thirty-six Views of Mount Fuji.]] The term aizuri-e (Japanese: "blue printed picture") usually refers to Japanese woodblock prints that are printed entirely or predominantly in blue. When a second color is used, it is usually red. Even if only a single type of blue ink was used, variations in lightness and darkness (value) could be achieved by superimposing multiple printings of parts of the design or by the application of a gradation of ink to the wooden printing block (bokashi).
