Intaglio is a kind of printmaking in which a carved design is coated with ink and wiped with a cloth; the resulting print comes from ink in the carved grooves.
In intaglio, the shape that ends up printed on paper, cloth, or some other surface is carved out of a metal plate. The plate is either engraved by hand or burned with acid, using a technique called "etching." You can also use the word intaglio to describe a type of sculpture or jewelry making in which designs are etched or engraved. In Italian, intaglio means "engraved work," from intagliare, "to cut in."
