Photogravure. Photogravure (in French héliogravure) is a process for printing photographs, also sometimes used for reproductive intaglio printmaking. It is a 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 ...
Other terms often used for printed engravings are copper engraving, copper-plate engraving or line engraving. Steel engraving is the same technique, on steel or steel-faced plates, and was mostly used for banknotes, illustrations for books, magazines and reproductive prints, letterheads and similar uses from about 1790 to the early 20th century, when the technique became less popular, except ...

[2] It is the direct opposite of a relief print where the parts of the matrix that make the image ...
The wiping leaves ink in the incisions. You may also use a folded piece of organza silk to do the final wipe. If copper or zinc plates are used, then the plate surface is left very clean and therefore white in the print. If steel plate is used, then the plate's natural tooth gives the print a grey background similar to the effects of aquatinting.
Printing the finished plate is the same for either method, and follows the normal way for an intaglio plate; the whole surface is inked, the ink is then wiped off the surface to leave ink only in the pits of the still rough areas below the original surface of the plate. The plate is put through a high-pressure printing press next to a sheet of ...
Drypoint. Drypoint is a printmaking technique of the intaglio family, in which an image is incised into a plate (or "matrix") with a hard-pointed "needle" of sharp metal or diamond point. In principle, the method is practically identical to engraving. The difference is in the use of tools, and that the raised ridge along the furrow is not ...
