  2. Electrotyping - Wikipedia

    en.wikipedia.org/wiki/Electrotyping

    A copper film (the electrotype) grows onto the electrically conducting coating of the mold. Electrotyping (also galvanoplasty) is a chemical method for forming metal parts that exactly reproduce a model. The method was invented by Moritz von Jacobi in Russia in 1838, and was immediately adopted for applications in printing and several other ...

  3. Intaglio (printmaking) - Wikipedia

    en.wikipedia.org/wiki/Intaglio_(printmaking)

    Intaglio (/ ɪnˈtæli.oʊ, - ˈtɑːli -/ in-TAL-ee-oh, -⁠TAH-lee-; [1] Italian: [inˈtaʎʎo]) is the family of printing and printmaking techniques in which the image is incised into a surface and the incised line or sunken area holds the ink. [2] It is the direct opposite of a relief print where the parts of the matrix that make the image ...

  4. Photogravure - Wikipedia

    en.wikipedia.org/wiki/Photogravure

    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 ...

  5. Microcontact printing - Wikipedia

    en.wikipedia.org/wiki/Microcontact_printing

    Microcontact printing (or μCP) is a form of soft lithography that uses the relief patterns on a master polydimethylsiloxane (PDMS) stamp or Urethane rubber micro stamp [1] to form patterns of self-assembled monolayers (SAMs) of ink on the surface of a substrate through conformal contact as in the case of nanotransfer printing (nTP). [2]

  6. Plate reader - Wikipedia

    en.wikipedia.org/wiki/Plate_reader

    Plate reader. Plate readers, also known as microplate readers or microplate photometers, are instruments which are used to detect biological, chemical or physical events of samples in microtiter plates. They are widely used in research, drug discovery, [1] bioassay validation, quality control and manufacturing processes in the pharmaceutical ...

  7. Electroplating - Wikipedia

    en.wikipedia.org/wiki/Electroplating

    Electroplating. Copper electroplating machine for layering PCBs. Electroplating, also known as electrochemical deposition or electrodeposition, is a process for producing a metal coating on a solid substrate through the reduction of cations of that metal by means of a direct electric current. The part to be coated acts as the cathode (negative ...

  8. Conservation and restoration of photographic plates - Wikipedia

    en.wikipedia.org/wiki/Conservation_and...

    Glass plate negative. The conservation and restoration of photographic plates is the practice of caring for and maintaining photographic plates to preserve their materials and content. The practice includes the measures that can be taken by conservators, curators, collection managers, and other professionals to conserve the material unique to ...

  9. Electroless copper plating - Wikipedia

    en.wikipedia.org/wiki/Electroless_copper_plating

    Electroless copper plating. Electroless copper plating is a chemical process that deposits an even layer of copper on the surface of a solid substrate, like metal or plastic. The process involves dipping the substrate in a water solution containing copper salts and a reducing agent such as formaldehyde. [1]
