What is a photogravure print?

Photogravure is an intaglio printmaking or photo-mechanical process whereby a copper plate is grained (adding a pattern to the plate) and then coated with a light-sensitive gelatin tissue which had been exposed to a film positive, and then etched, resulting in a high quality intaglio plate that can reproduce detailed

Accordingly, how do you identify photogravure?

It is quite easy to identify a photogravure print. Look at the print with a good magnifying glass, and you will see a characteristic honeycomb appearance. This is caused by the grid used in the printing process. The image also appears soft and the dark areas seem pitted, as seen below.
