4 Preferred Printmaking Techniques

By Clara Berta


Printmaking is actually a process for making a masterwork in ink; the work known as a print is made indirectly, via the transfer of ink from the surface where the work was initially sketched or composed. Undertaking this printmaking can be achieved in the following methods. The most used are the woodcut, etching, lithography, as well as screen-printing. Other printmaking methods include chine-coll, collography, monotyping, engraving, drypoint, mezzotint, linocut, aquatint as well as batik. These techniques could likewise be merged.

Woodcut is a form of relief print considered to be the first printmaking method, dating back to 9th century China. The artist draws a sketch on a plank of wood and after that uses sharpened instruments to be able to carve away the areas of the chunk which he/she does not like to have the ink. The raised parts of the block are inked with a brayer and then a sheet of paper, possibly somewhat damp, is put over the block. The block is then rubbed with a baren or spoon, or is run through the press.

Etching prints are usually linear and often possess details as well as contours. Lines could differ from smooth to sketchy. A wax-like acid-resist, referred to as a ground, will be placed on a metal plate. After the ground has dried up, the artisan makes use of a sharpened tool to be able to scrape into the ground, exposing the metal. The plate is then entirely submerged in an acid which takes away at the totally exposed steel. This process is known as biting. The waxy resist protects the acid solution from biting the parts of the plate that have not been scraped into. The longer the plate continues to be in the acid solution, the deeper the incisions turn into. The plate will be taken out from the acid and the ground is removed with a solvent like turpentine. The entire plate will be inked. A wad of cloth is frequently used to force the ink into the incised outlines. The surface area will be wiped clean using a piece of stiff fabric referred to as tarlatan or newsprint paper. The wiping leaves ink solely in the incisions. A moist sheet of paper is placed above the plate and it is run through the press.

Lithography is a printing technology developed a method of imaging limestone from which a print was made. Using the concept that oil and water tend not to mix, an aluminum or plastic plate is coated with a photopolymer film that is totally exposed to light by using a photographic mask. The exposed parts are chemically "hardened," and the unexposed parts will be dissolved when the plate is subjected to a chemical procedure. When printing a page, the plate is dampened, and the water adheres merely to the unexposed, non-image areas, that repell the greasy ink that is applied to the plate immediately thereafter.

Screen printing, also referred to as "silk-screening" produces vibrant color by using a stencil technique. The artisan draws an image on a sheet of paper or plastic film can likewise be used. The graphic is cut out making a stencil. A screen is made from a piece of fabric stretched over a wooden frame. The stencil is attached to the screen. The screen is then placed on top of a piece of dry paper or fabric. Ink is then placed across the top length of the screen. A squeegee (rubber blade) will be used to distribute the ink across the screen, over the stencil, as well as onto the paper/fabric. The screen is lifted as well as the graphic will be moved onto the paper/fabric. Each color requires a separate stencil. The screen can be re-used right after cleaning.
