List Of Duplicating Processes
This is a partial list of text and image duplicating processes used in business and government from the Industrial Revolution forward. Some are mechanical and some are chemical. There is naturally some overlap with printing processes and photographic processes, but the challenge of precisely duplicating business letters, forms, contracts, and other paperwork prompted some unique solutions as well. There were many short-lived inventions along the way.

Industrial Revolution
The Industrial Revolution was the transition to new manufacturing processes in Great Britain, continental Europe, and the United States, that occurred during the period from around 1760 to about 1820–1840. This transition included going from hand production methods to machines, new chemical manufacturing and iron production processes, the increasing use of steam power and water power, the development of machine tools and the rise of the mechanized factory system. Output greatly increased, and a result was an unprecedented rise in population and in the rate of population growth. Textiles were the dominant industry of the Industrial Revolution in terms of employment, value of output and capital invested. The textile industry was also the first to use modern production methods. The Industrial Revolution began in Great Britain, and many of the technological and architectural innovations were of British origin. By the mid-18th century, Britain was the world's leadi ...

Letterpress Printing
Letterpress printing is a technique of relief printing. Using a printing press, the process allows many copies to be produced by repeated direct impression of an inked, raised surface against sheets or a continuous roll of paper. 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 from the type, which creates an impression on the paper. In practice, letterpress also includes other forms of relief printing with printing presses, such as wood engravings, photo-etched zinc "cuts" (plates), and linoleum blocks, which can be used alongside metal type, or wood type in a single operation, as well as stereotypes and electrotypes of type and blocks. With certain letterpress units, it is also possible to join movable type with slugs cast using hot metal typesetting. In theory, anything that is "type high" and so forms a layer exactly 0.918 in. thick between the bed and the paper can be printed using l ...

Photolithography
In integrated circuit manufacturing, photolithography or optical lithography is a general term used for techniques that use light to produce minutely patterned thin films of suitable materials over a substrate, such as a silicon wafer, to protect selected areas of it during subsequent etching, deposition, or implantation operations. Typically, ultraviolet light is used to transfer a geometric design from an optical mask to a light-sensitive chemical (photoresist) coated on the substrate. The photoresist either breaks down or hardens where it is exposed to light. The patterned film is then created by removing the softer parts of the coating with appropriate solvents. Conventional photoresists typically consists of three components: resin, sensitizer, and solvent. Photolithography processes can be classified according to the type of light used, such as ultraviolet, deep ultraviolet, extreme ultraviolet, or X-ray. The wavelength of light used determines the minimum feature si ...

Offset Lithography
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. Ink rollers transfer ink to the image areas of the image carrier, while a water roller applies a water-based film to the non-image areas. The modern "web" process feeds a large reel of paper through a large press machine in several parts, typically for several meters, which then prints continuously as the paper is fed through. Development of the offset press came in two versions: in 1875 by Robert Barclay of England for printing on tin and in 1904 by Ira Washington Rubel of the United States for printing on paper. History Lithography was initially created to be an inexpensive method of reproducing artwork.Carter, Rob, Ben Day, Philip Meggs. ...

Autographic Process
The autographic system for roll film was launched by Kodak in 1914, and allowed the photographer to add written information on the film at the time of exposure. The system was patented by Henry Jacques Gaisman, inventor and safety razor manufacturer. George Eastman purchased the rights for US$300,000. It consisted of a tissue-like carbon paper sandwiched between the film and the paper backing. Text was entered using a metal stylus, and would appear in the margin of the processed print. The system was common on early consumer cameras but became unpopular in the 1920s, and was discontinued in 1932. Kodak's autographic films had "A" as the first part of the film size designation. Thus, standard 122 film would be labeled "122" and autographic 122 would be "A122". Autographic roll film sizes were A116, A118, A120, A122, A123, A126, A127, and A130. The autographic feature was marketed as having no extra charge. In 1915, Kodak also sold upgrade autographic backs for their existing c ...

Anastatic Lithography
Anastatic lithography is a method of printing developed by 1840 in Erfurt. The technique provided a means for facsimile reproduction, which was developed and promoted by Werner and William Siemens Sir Carl Wilhelm Siemens (4 April 1823 – 19 November 1883), anglicised to Charles William Siemens, was a German-British electrical engineer and businessman. Biography Siemens was born in the village of Lenthe, today part of Gehrden, near Han .... Whereas the reproduction of the four pages of the 25th September 1841 issue of '' The Athenaeum'', a London scientific journal, was so true to the original that that it caused concerns expressed in an article "Printing and Piracy-New Discovery" which was published in the issue No. 736 published December 4, 1841.

Lithograph
Lithography () is a planographic method of printing originally based on the immiscibility of oil and water. The printing is from a stone (lithographic limestone) or a metal plate with a smooth surface. It was invented in 1796 by the German author and actor Alois Senefelder and was initially used mostly for musical scores and maps.Meggs, Philip B. A History of Graphic Design. (1998) John Wiley & Sons, Inc. p 146 Carter, Rob, Ben Day, Philip Meggs. Typographic Design: Form and Communication, Third Edition. (2002) John Wiley & Sons, Inc. p 11 Lithography can be used to print text or images onto paper or other suitable material. A lithograph is something printed by lithography, but this term is only used for fine art prints and some other, mostly older, types of printed matter, not for those made by modern commercial lithography. Originally, the image to be printed was drawn with a greasy substance, such as oil, fat, or wax onto the surface of a smooth and flat limestone plat ...

Spirit Duplicator
A spirit duplicator (also referred to as a Rexograph or Ditto machine in North America, Banda machine in the UK, Gestetner machine in Australia) is a printing method invented in 1923 by Wilhelm Ritzerfeld that was commonly used for much of the rest of the 20th century. The term "spirit duplicator" refers to the alcohols that were a major component of the solvents used as "inks" in these machines. The device coexisted alongside the mimeograph. Spirit duplicators were used mainly by schools, churches, clubs, and other small organizations, such as in the production of fanzines, because of the limited number of copies one could make from an original, along with the low cost (and corresponding low quality) of copying. History The spirit duplicator was invented in 1923 by Wilhelm Ritzerfeld. The best-known manufacturer in the United States and the world was Ditto Corporation of Illinois. Copiers in the United Kingdom were commonly manufactured by Associated Automation Ltd of Willes ...

Flexography
Flexography (often abbreviated to flexo) is a form of printing process which utilizes a flexible relief plate. It is essentially a modern version of letterpress, evolved with high speed rotary functionality, which can be used for printing on almost any type of substrate, including plastic, metallic films, cellophane, and paper. It is widely used for printing on the non-porous substrates required for various types of food packaging (it is also well suited for printing large areas of solid colour). History In 1890, the first such patented press was built in Liverpool, England by Bibby, Baron and Sons. The water-based ink smeared easily, leading the device to be known as "Bibby's Folly". In the early 1900s, other European presses using rubber printing plates and aniline oil-based ink were developed. This led to the process being called "aniline printing". By the 1920s, most presses were made in Germany, where the process was called "gummidruck", or rubber printing. In modern-day G ...

Collography
Collagraphy (sometimes spelled collography) is a printmaking process introduced in 1955 by Glen Alps in which materials are applied to a rigid substrate (such as paperboard or wood). The word is derived from the Greek word ''koll'' or ''kolla'', meaning glue, and ''graph'', meaning the activity of drawing. The plate can be intaglio-inked, inked with a roller or paintbrush or some combination thereof. Ink or pigment is applied to the resulting collage and the board is used to print onto paper or another material using either a printing press or various hand tools. The resulting print is termed a collagraph. Substances such as carborundum, acrylic texture mediums, sandpapers, textiles, bubble wrap, string or other fibres, cut card, leaves and grass can all be used in creating the collagraph plate. In some instances, leaves can be used as a source of pigment by rubbing them onto the surface of the plate. Different tonal effects and vibrant colours can be achieved with the technique ...
