Several process are available using stencil lithography: material deposition and etching, as well as implantation of ions. Different stencil requirements are necessary for the various processes, e. g. an extra etch-resistant layer on the backside of the stencil for etching (if the membrane material is sensitive to the etching process) or a conductive layer on the backside of the stencil for ...
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 ...
Commercial etching techniques also gradually replaced steel engraving. All the illustrations in the Encyclopædia Britannica of 1911 are steel engravings. [citation needed] Steel engraving is still done today, but to a much lesser extent. Today, most printing is done using computerized stencils instead of a steel plate to transfer ink.
Large panels can be found as part of outdoor installation pieces or for interior use. Dedicated lighting is often part of the artwork. Techniques used include stained glass, carving (wheel carving, engraving, or acid etching), frosting, enameling, and gilding (including Angel gilding).
The combined benefits of UV stability and the high image resolution of silver photography along with the abrasion and corrosion resistance of anodized aluminum are used to advantage in applications where permanent product identification is critical such as equipment nameplates, IUID barcode labels, outdoor signage, safety/warning plates ...
This is repeated many times. Like etching, aquatint uses the application of a mordant (acid) to etch into the metal plate. Where etching uses a needle to scratch through an acid-proof resist and make lines, aquatint uses powdered rosin (resin) to create a tonal effect. The rosin is acid resistant and typically adhered to the plate by controlled ...
