What is a photogravure?

Photogravure

Invented in the 1850's, photogravure is a process in which a plate is coated with a light-sensitive ground. The plate is then exposed to light, which transfers the image onto the ground, and then immersed in acid. Where the ground is exposed, the acid etches the image into the plate, creating an image that is almost photographic in appearance.
