Reduksjonstrykk

Reduksjonstrykk, also known as reduction prints, are a type of printmaking technique that involves the use of acid to selectively remove parts of a metal plate, typically copper or zinc, to create an image. This process is a form of intaglio printing, where the image is created by the spaces between the raised areas of the plate. The term "reduksjonstrykk" is derived from the Norwegian words "reduksjon," meaning reduction, and "trykk," meaning print.

The technique was developed in the 15th century and became popular in Europe during the Renaissance. It allowed artists to create intricate and detailed images with a high degree of control over the printing process. The artist would first draw the image onto the metal plate using a needle or a stylus. The plate was then coated with a wax-like substance, which was removed from the areas where the image was to be printed. The plate was then treated with an acid, which dissolved the exposed metal, creating the intaglio effect.

Reduksjonstrykk is known for its ability to produce high-quality prints with a rich, textured surface. The technique is often used for fine art prints, as well as for commercial printing of illustrations and maps. It is also used in the production of banknotes and other security documents, due to its ability to create unique and difficult-to-counterfeit images.

The process of creating a reduksjonstrykk involves several steps, including the preparation of the plate, the application of the image, the waxing and acid treatment, and the printing itself. The final print is typically produced on high-quality paper, such as rag paper or vellum, to ensure the best possible reproduction of the image. The technique requires a high degree of skill and precision, and the final print is often considered a valuable and unique work of art.
