Printmaking-the process of reproducing images on a flat surface; three types are relief block (linoleum, wood), intaglio (etching, engraving), and stencil (silkscreen).


Woodblock Print- John Cole
Relief:The basic principle of relief printing is to create an image on paper from the raised surface of the matrix. The artist draws onto a surface (the block or matrix) and then cuts away the areas that are not to form part of the image. These areas are the negative parts of the image, or the spaces around what we see generally consider to be the image. Thus the ink only reaches the areas the artist does not touch. The block is inked and a piece of paper laid over it. The artist then either rubs the paper using their hand or a hard, smooth object or runs it through a printing press. The image produced on the paper mirrors that on the block. Woodcuts and linocut are the most common examples of relief prints

William H. Dryden Jr.
Intaglio:Intaglio is the precise opposite of relief printmaking. In this process the artist carves the image onto the matrix and then rubs ink into these carved lines, making sure that the untouched areas are cleaned of ink. In the intaglio process the paper is previously soaked in water. When it is laid over the matrix and the squashed through the printing press, the soft paper is pushed into the grooves of the inked lines, thus transferring the image onto the paper. Many intaglio processes involve creating the grooves with acids that eat into a metal plate. Variations of the Intaglio technique include Engraving, Etching, Aquatint, Mezzotint and Aquatint.

Serigraphy: All serigraphic prints are based on the concept of stencil. The stencil technique uses a thin sheet of impenetrable, durable material with a design cut into it. This is placed over a receiving surface (paper, canvas, etc.). Thus the paint or dye applied over the surface of the stencil only reaches the receiving surface where the design has been cut away.
Drypoint Lithography- Bill Hosterman
Lithography:The concept of lithography is based on the mutual incompatibility of oil and water; the capacity of limestone to absorb and retain water and the disposition of oily substances to adhere to limestone. The highly polished nature of the surface is receptive to the oil that is spread over it. Senefelder discovered that by chemically treating the surface of limestone, and drawing onto it with a grease crayon, only the areas touched by the grease crayon would take the printing ink. Therefore, by drawing onto the treated stone in this way, inking it, covering it with a damp paper and running it through a printing press, the image is transferred exactly onto the paper

Class Activity:
Students were given some etching tools, including burnishers and scrapers, as well as soft block tiles, cardboard, string, styrofoam, paint, rollers, and fabric. Students etched designs into blocks using the relief process as described above, and used a form of the intaglio process with the styrofoam pieces. Students also created prints by gluing string onto a piece of cardboard to form a design, then covering with paint and created prints this way.
