Technique of Photogravure
Photogravure, based on gelatine, is just one of many methods of reproduction. Gelatine itself is not sensitive to light, a chemical substance is required for this: Potassium diichromate K2Cr2O7. A gelatin layer soaked with potassium dichromate becomes insoluble in water after exposure to natural light (UV rays) at normal temperatures.
History of Photogravue
The history of the photogravure reaches back up to the photographic experiments of Nicéphore Niépce (1765-1833). In 1816 he tried to project a picture by a camera obscura so that it could be brought in a printable form. This first quite primitive photomechanical process is called Niépce Gravure Heliographique.
