Explanation:

Intaglio printing is one of the printmaking processes that entails: engraving(Burin, a wedge or lozenge-shaped forms the image on the plate), etching (aids engraving of an image to a metal plate covered with an acid-resistant ground), drypoint (the burr is inked and it forms a velvety appearance), aquatint and mezzotint (indenting the printing plate by rocking a toothed metal tool across the surface. It's mostly done for portrait paintings). In this case, the printing is carried out via ink stationed beneath the plate surface.

It is mostly carried out on a metal plate (Copper, zinc, or steel plates). It employs the use of a sharp object or concentrated acid solution in incised Grooves or pits to the plate. Greasy ink is also employed.
