What is the difference between an etching and an engraving?
They can be synonyms of each other. Both carved and then you make a relief or marking on some kind of surface from that. Both can be paper, metal, leather, wood, all sorts of materials. But how those surfaces are marked can make the difference. Engraved usually means cutting into the surface to make grooves or markings. Etching is usually done with some kind of acid on metal. Both can be used by themselves for decorations or printed to make a copy of the design. So the difference is how the molds or plates are made if they are used for printing.
