Linocut and woodcut prints are a form of relief print. In this process, artists will carve a design into a wooden or linoleum panel and then roll ink onto the surface. The canvas or paper is then placed on top of the panel, and pressure is applied. The image that transfers comes from the raised parts of the design on the panel, and not the gauged parts.
This form of printmaking is one of the true originals and oldest forms of printmaking. Originating in China after the invention of paper around 105 AD yet it is still popular today.
