This document discusses the four main types of printmaking: relief printing, intaglio, planography (lithography), and stencil (serigraphy). Relief printing involves cutting away areas of a surface to create a raised image. Intaglio involves engraving or cutting an image into a surface. Lithography uses a greasy drawing on a flat surface that interacts with water and ink. Serigraphy uses a stencil made of fabric with cut out areas to transfer ink through to the printing surface. The document provides details on the tools and processes used for each type of printmaking.
