Synonym discussion
Sense: noun/1
Photoengraving, photogravure, photoetching, and lithography are all printing techniques, but they differ in method and result. Photoengraving uses acid to create a raised (relief) surface on a metal plate, ideal for reproducing line drawings and halftone photographs in newspapers and books. Photogravure also uses acid on a copper plate but produces a recessed (intaglio) surface, giving a softer, continuous-tone look. Photoetching overlaps with photoengraving but often refers narrowly to the chemical etching step rather than the full printmaking process. Lithography, by contrast, relies on the repulsion between oil and water on a flat stone or metal surface — no acid etching is involved. For example, a classic newspaper photograph was likely made by photoengraving, while fine-art photography books from the early 1900s often used photogravure.

Etymology
Photoengraving joins the Greek-derived 'photo-' (meaning light, from phōs, phōt-) with the English word 'engraving' (from the French 'graver', meaning to carve or cut). The term emerged in the mid-19th century when printmakers first combined photography with acid-etching to automate the creation of printing plates.
