A collograph is a printing technique in which the artist adds materials to a rigid background such as wood or cardboard. The resulting design is built up like a collage, creating a relief. The design is then inked and printed on paper. The term "collography" is derived from the Greek word collo, meaning glue, and the English word graph meaning the activity of drawing.

Drypoint etching

is a form of printmaking that has been used for centuries to produce beautifully detailed artwork. Like other intaglio styles of printmaking, drypoint etching produces a print by incising an image into the surface of a plate. However, unlike etching which requires acid to burn into the plate, drypoint etching simply relies on a sharp, small tool. When the plate is inked, ink remains in the groves that have been etched into it and produces the print when pressed with paper.
