Drypointing is an intaglio printmaking process where the artist works directly onto a plate, usually metal or plastic. A sharp tool is used (in Anna's case a diamond point) which displaces the plate material and this forms a raised burr on the surface. The printing ink is held both in the line and the raised burr and prints with a rich velvety quality. The inking up process and the pressure exerted by the press soon wears down the burr on the surface and the prints lose their richness and clarity. For this reason Anna keeps her editions to 5.
