Aquatint is an intaglio printmaking technique, a variant of etching that produces areas of tone rather than lines. For this reason it has mostly been used in conjunction with etching, to give both lines and shaded tone. It has also been used historically to print in colour, both by printing with multiple plates in different colours, and by making monochrome prints that were then hand-coloured with watercolour.

Intaglio 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. It is the direct opposite of a relief print where the parts of the matrix that make the image stand above the main surface.
Micro-topography of an ordinary French post stamp (detail) showing the thickness of ink obtained by intaglio. The words la Poste appeared in white on red background and hence corresponds to areas with a lack of ink.
