Photogravure is a process of etching continuous tones into copper with a sensitized gelatin pigment paper resist (aka carbon tissue) using a continuous tone positive and aquatint screen or dustgrain aquatint. The process was invented by William H. F. Talbot and Karl Klic in the late 1800s for archivally reproducing fine photographic prints. They also employed the use of the dustgrain for its organic grain and fine tonal resolution as well as deeper etched shadows. The tones of the positive are etched into the copper plate in the proportion to the density giving a multi depth layer of ink and a very perceivable and virtually infinite range of tones. Careful timing of the different etching baths also adds another way of controlling the tonal curves. This process yields an etched plate that can be retouched and re-worked with any of the traditional etching processes. The copper plate is often electroplated with iron (steel faced) for printing very consistent and/or long editions. This is still the absolute best way to make a photographic intaglio plate for printing.
Please see my site for more info. I teach the Talbot-Klic dustgrain method as well as screen exposures using my own analogue aquatint screens. Each student will etch 2 7x9 plates. I have one space available.
