The Photogravure Process. A photogravure is a photographic image produced from an engraving plate --an expensive and rarely used process today. Through the transfer of etching ink from an etched copperplate to special dampened paper run through an etching press, this process creates an image that registers an extraordinary variety of tones. This unique tonal range comes from photogravure's variable depth of etch--the shadows are etched many times deeper than the highlights unlike the halftone processes that merely vary dot size. The prints produced via this process have the subtle tones of a photograph and the art quality of a lithograph, making them extraordinarily collectible items.
