Printmaking is the process of making multiple artworks through various techniques involving transferring ink from a matrix or screen onto paper or other material. The main printmaking techniques discussed include intaglio methods like engraving, etching, mezzotint and aquatint where ink is pressed into lines or tones on a plate before printing; lithography which uses the repulsion of oil and water to create images on stone or metal plates; and screenprinting which forces ink through a fabric stencil using a squeegee. Artists over centuries have experimented with these techniques to produce artistic prints.
