Offset printing is a common printing technique in which the inked image is transferred (or "offset") from a plate to a rubber blanket and then to the printing surface. When used in combination with the lithographic process, which is based on the repulsion of oil and water , the offset technique employs a flat ( planographic ) image carrier.
For offset lithography, which depends on photographic processes, flexible aluminum, polyester, mylar or paper printing plates are used instead of stone tablets. Modern printing plates have a brushed or roughened texture and are covered with a photosensitive emulsion.
Letterpress printing is a technique of relief printing for producing many copies by repeated direct impression of an inked, raised surface against individual sheets of paper or a continuous roll of paper. [ 1] A worker composes and locks movable type into the "bed" or "chase" of a press, inks it, and presses paper against it to transfer the ink ...
Waterless printing is an offset lithographic printing process that eliminates the use of water or the dampening system used in conventional printing. [ 1] Unlike traditional printing presses, waterless offset presses do not use a dampening solution to clear the press of ink. [ 2] Proponents of the technology claim efficiency and ecological ...
Intaglio ( / ɪnˈtælioʊ, - ˈtɑː -/ in-TAL-ee-oh, -TAH-; [ 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 ...
e. In printing and typography, hot metal typesetting (also called mechanical typesetting, hot lead typesetting, hot metal, and hot type) is a technology for typesetting text in letterpress printing. This method injects molten type metal into a mold that has the shape of one or more glyphs. The resulting sorts or slugs are later used to press ...
The plates, called stereotypes, are coated with ink, then pressed against a continuous roll of paper. Rotary letterpress printing was used in the mid-twentieth century to print most major newspapers. In offset lithography, the image is chemically applied to a plate, generally through exposure of photosensitive layers on the plate material.
The newspaper production process begins with gathering news stories, articles, opinions, advertorials and advertisements to printing and folding of the hard copy. Usually, the news items are printed onto newsprint. The whole production process can be divided into four parts: Content gathering, Pre-press, Press and Post-press.
