Erwinotype

from Wikipedia, the free encyclopedia

The Erwinotype , also referred to in the literature as the Erwino method, is a photomechanical art print method developed by Erwin Quedenfeldt around 1910, named after his first name and patented with this name.

He tried to spread his method through licensing, but had almost no success, which is why he finally licensed it exclusively to the Dutch photographer Henri Berssenbrugge in November 1921 with all rights of use .

Typical of the Erwinotype is the uniquely strong mixture of methods of photomechanical reproduction with artistic-graphic processing methods, such as scraping, scratching or sanding on the printing matrix and their different colored coloring during the printing process, compared to other art print processes of the time. Erwinotypes from one and the same edition therefore have a more distinctive unique character than prints from other dye transfer processes.

Quedenfeldt himself describes his process in an advertisement in a nutshell: "Erwinopruck is transfer printing with the ball of the hand, single and multi-colored and without sticky oil paints, linseed oil, bromine oil. Suction, dust or etching process. Licenses only granted to artists. Working photographic designer Dr. Erwin Quedenfeldt, Vienna XIII, Trazerberggasse 9 ".

From a technical point of view, the Erwinotype is a photomechanical source relief and - like all dye transfer methods - belongs to the group of photomechanical relief printing processes.
