Monochrome printmaking
Monochrome printmaking is a generic term for any printmaking technique that produces only shades of a single color. While the term may include ordinary printing with only two colors — "ink" and "no ink" — it usually implies the ability to produce several intermediate colors between those two extremes.
In contrast with color printing, monochrome printing needs only a single ink and may require only a single pass of the paper through the printing press.
