Depressions are engraved or etched into a flat printing plate. Likely not to scale: grooves can be less than a millimetre wide.
The plate is covered in ink.
The ink is wiped off the surface of the plate, but remains in the grooves.
Paper is placed on the plate and compressed, such as by a heavy roller.
The paper is removed, and the ink has been transferred from the plate to the paper.
Intaglio (/ɪnˈtælioʊ,-ˈtɑː-/in-TAL-ee-oh, -TAH-;[1]Italian:[inˈtaʎʎo]) is the family of printing and printmaking techniques in which the image is incised into a surface and the incised line or sunken area holds the ink.[2] It is the direct opposite of a relief print where the parts of the matrix that make the image stand above the main surface.
After the decline of the main relief technique of woodcut around 1550, the intaglio techniques dominated both artistic printmaking as well as most types of illustration and popular prints until the mid 19th century.
[5] With a silent "g," the word "intaglio," which has its roots in Italy, describes prints created from plates where the ink-bearing regions are recessed beneath the plate's surface. Though brass, zinc, and other materials are occasionally utilized, copper is the most common material for the plates.
