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 ...
It is limited to materials with a thickness of 0.0005 to 0.080 in (0.013 to 2.032 mm). Metals include aluminium, brass, copper, inconel, manganese, nickel, silver, steel, stainless steel, zinc and titanium. Photochemical machining is a form of photo engraving, and a similar process in microfabrication is called photolithography.
A print made in 1907 from a photoengraved plate. It reproduces a sketch of Parga's castle made by Ludwig Salvator.. Photoengraving is a process that uses a light-sensitive photoresist applied to the surface to be engraved to create a mask that protects some areas during a subsequent operation which etches, dissolves, or otherwise removes some or all of the material from the unshielded areas of ...
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.
Photolithography allows the complex wiring of an electronic system to be rapidly, economically, and accurately reproduced as if run off a printing press. The general process is applying photoresist, exposing image to ultraviolet rays, and then etching to remove the copper-clad substrate. [28] A printed circuit board-4276
Photosensitive anodized aluminum, also referred to as photo anodized aluminum or photo metal, utilizes the porous nature of unsealed anodized aluminum [1] to create a sub-surface image. The image can be created either through exposure and development of an anodic layer impregnated with silver compounds [2] (Type 1 [3]), much like traditional ...
