Paper (typically pages from old phone books) may be used for a final wipe of the lightest areas of the image. Some printmakers will use their bare hand instead to wipe these areas. Once the desired amount of ink is removed, the plate is run through an etching press along with a piece of dampened paper to produce a print.
Dry etching refers to the removal of material, typically a masked pattern of semiconductor material, by exposing the material to a bombardment of ions (usually a plasma of reactive gases such as fluorocarbons, oxygen, chlorine, boron trichloride; sometimes with addition of nitrogen, argon, helium and other gases) that dislodge portions of the material from the exposed surface.

Etching is a critically important process module in fabrication, and every wafer undergoes many etching steps before it is complete. For many etch steps, part of the wafer is protected from the etchant by a "masking" material which resists etching. In some cases, the masking material is a photoresist which has been patterned using photolithography.
The term usually refers to the arts that rely more on line, color or tone, especially drawing and the various forms of engraving; [2] it is sometimes understood to refer specifically to drawing and the various printmaking processes, [2] such as line engraving, aquatint, drypoint, etching, mezzotint, monotype, lithography, and screen printing ...
Much greater pressure is then needed to force the paper into the channels containing the ink, so a high-pressure press is normally needed. Intaglio techniques include engraving, etching, and drypoint. In the planographic family of printing, the entire surface of the matrix is flat, and some areas are treated to create the print image.

Chemical milling or industrial etching is the subtractive manufacturing process of using baths of temperature-regulated etching chemicals to remove material to create an object with the desired shape. [1] [2] Other names for chemical etching include photo etching, chemical etching, photo chemical etching and photochemical machining. It is ...
Mukul Chandra Dey (23 July 1895 – 1 March 1989) was one of five children of Purnashashi Devi and Kula Chandra Dey. [1] He was a student of Rabindranath Tagore's Santiniketan and is considered as a pioneer of drypoint-etching in India.
