Linocut  is a printmaking technique, a variant of woodcut in which a sheet of linoleum (sometimes  mounted on a wooden block) is used for the relief  surface. A design is cut into the linoleum surface  with a sharp knife, V-shaped chisel or gouge, with  the raised (uncarved) areas representing a reversal  (mirror image) of the parts to show printed. The  linoleum sheet is inked with a roller (called a brayer),  and then impressed onto paper or fabric. The actual  printing can be done by hand or with a press.

Drypoint is a printmaking technique of the intaglio family, in which an image is incised into a plate (or "matrix") with a hard-pointed "needle" of sharp metal or diamond point. Traditionally the plate was copper, but now acetate, zinc are also commonly used. Like etching, drypoint is easier for an artist trained in drawing to master than engraving, as the technique of using the needle is closer to using a

pencil than the engraver's burin.

     Etching is the process of using strong acid to cut into the unprotected parts of a metal surface to create a design in intaglio in the metal (the original process—in modern manufacturing other chemicals may be used on other types of material). As an intaglio method of printmaking it is, along with engraving, the most important technique for old master prints, and remains widely used today.

Aquatint is a variant of etching. Like etching,  aquatint uses the application of acid to make the marks in the metal plate. Where the etching    technique uses a needle to make lines that print in black (or whatever colour ink is used), aquatint uses  powdered resin which is acid resistant in the  ground  to create a tonal effect. The tonal variation is controlled by the level of acid exposure over large areas, and thus the image is shaped by large  sections at a time. Another tonal technique, mezzotint, begins with a plate surface that is evenly  indented so that it will carry a fairly dark tone of ink,  then smoothing areas to make them carry less ink and thus print a lighter shade; or, beginning with a smooth plate, areas are roughened to make them darker; or, these two techniques may be combined.

Lithography is a method for printing using a stone (lithographic limestone) or a metal plate with a completely smooth surface. Invented in 1796 by Bavarian author Alois Senefelder as a low-cost method of publishing theatrical works, lithography can be used to print text or artwork onto paper or another suitable material.
