Intagliotype
The intagliotype , also known as the polymeric gravure technique , is a modern form of gravure printing .
The process allows etchings to be made without the use of strong acids. In contrast to mechanically generated etching, the motif is brought to a printing plate sensitized by means of a special photopolymer film by means of contact exposure, so that digitally created templates can also be exposed. The printing form is then washed out with a light soda solution ( sodium carbonate ). Stabilized with vinegar, can be printed immediately in short runs. The advantages of this process compared to etching are its environmental friendliness and health compatibility and the ability to reproduce photo and digital originals. Due to a chain of dependencies in the creation of the print such as material and original quality , exposure intensity and duration, duration of washing, the type of application and the viscosity of the printing ink as well as the paper quality used, the reproduction quality is very variable. In this respect, the intagliotype is limited to artistic use and is z. B. popular in art education.
The development The stress-free gravure printing process was developed around 1995 by Professor Keith Howard. Howard, a native of Australia who teaches at various art schools in Canada and (...) in the United States, was regularly exposed to toxic chemicals that are used in traditional gravure techniques from teaching in the gravure studios. He became seriously ill. Inhaling the vapors or dust of these chemicals such as nitric acid, asphalt dust, alcohol, turpentine substitute, etc. or the transmission through skin contact generally leads to considerable damage to health, starting with headaches, migraines, lung problems and skin rashes, later kidney and spleen problems are often added . Many artists accept these symptoms of illness as an inevitable evil in their work. A famous recent example is Horst Jansen.
Basic principle The intagliotype makes use of the property of photopolymer film which is hardened by UV light irradiation, i. H. Long stable molecular chains are formed by exposure to UV light. If certain areas are covered during exposure, these remain soft and can be removed by a weak lye, the developer. The film is neutralized with vinegar water and stabilized with heat. from: Junge Kunst No. 49, 2002, pp. 50–51, Rita Helmholtz
