Forme (printing)
In typesetting, a forme (or form) is imposed by a ''stoneman'' working on a flat ''imposition stone'' when they assemble the loose components of a page (or number of simultaneously printed pages) into a locked arrangement, inside a chase, ready for printing. If metal type is kept locked up in the typeset document for long periods to allow reprint, this is called "standing type". There are many types of formes in printing in general. The design of the printing surface and the material of the forme depend on the printing process employed. For instance, in letterpress printing, the forme is composed of type or stereotypes made from various materials. In ''intaglio'' printing, etched or engraved metallic cylinders are used, while offset printing employs chemically treated metal plates. In screen printing, the forme consists of a mesh with non-printing areas made impermeable to ink. In flexography, printing is done using either a directly engraved rubber cylinder or a digitally imag ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Johannes Gutenberg
Johannes Gensfleisch zur Laden zum Gutenberg ( – 3 February 1468) was a German inventor and Artisan, craftsman who invented the movable type, movable-type printing press. Though movable type was already in use in East Asia, Gutenberg's invention of the printing press enabled a much faster rate of printing. The printing press later Global spread of the printing press, spread across the world, and led to an information revolution and the unprecedented mass-spread of literature throughout Europe. It had a profound impact on the development of the Renaissance, Reformation, and Humanism, humanist movements. His many contributions to printing include the invention of a process for mass-producing movable type; the use of oil-based ink for printing books; adjustable molds; mechanical movable type; and the invention of a wooden printing press similar to the agricultural screw presses of the period. Gutenberg's method for making type is traditionally considered to have included a type ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Laser Engraving
Laser engraving is the practice of using lasers to engrave an object. The engraving process renders a design by physically cutting into the object to remove material. The technique does not involve the use of inks or tool bits that contact the engraving surface and wear out, giving it an advantage over alternative marking technologies, where inks or bit heads have to be replaced regularly. It is distinct from laser marking, which involves using a laser to mark an object via any of a variety of methods, including color change due to chemical alteration, charring, foaming, melting, ablation, and more. However, the term laser marking is also used as a generic term covering a broad spectrum of surfacing techniques including printing, hot-branding, and laser bonding. The machines for laser engraving and laser marking are the same, so the two terms are sometimes confused by those without relevant expertise. The impact of laser marking has been more pronounced for specially designe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Photopolymer
A photopolymer or light-activated resin is a polymer that changes its properties when exposed to light, often in the ultraviolet or visible region of the electromagnetic spectrum. These changes are often manifested structurally, for example hardening of the material occurs as a result of cross-linking when exposed to light. An example is shown below depicting a mixture of monomers, oligomers, and photoinitiators that conform into a hardened polymeric material through a process called curing. A wide variety of technologically useful applications rely on photopolymers; for example, some enamels and varnishes depend on photopolymer formulation for proper hardening upon exposure to light. In some instances, an enamel can cure in a fraction of a second when exposed to light, as opposed to thermally cured enamels which can require half an hour or longer. Curable materials are widely used for medical, printing, and photoresist technologies. Changes in structural and chemical propert ...

Ultraviolet
Ultraviolet radiation, also known as simply UV, is electromagnetic radiation of wavelengths of 10–400 nanometers, shorter than that of visible light, but longer than X-rays. UV radiation is present in sunlight and constitutes about 10% of the total electromagnetic radiation output from the Sun. It is also produced by electric arcs, Cherenkov radiation, and specialized lights, such as mercury-vapor lamps, tanning lamps, and black lights. The photons of ultraviolet have greater energy than those of visible light, from about 3.1 to 12 electron volts, around the minimum energy required to ionize atoms. Although long-wavelength ultraviolet is not considered an ionizing radiation because its photons lack sufficient energy, it can induce chemical reactions and cause many substances to glow or fluoresce. Many practical applications, including chemical and biological effects, are derived from the way that UV radiation can interact with organic molecules. The ...

Polyethylene
Polyethylene or polythene (abbreviated PE; IUPAC name polyethene or poly(methylene)) is the most commonly produced plastic. It is a polymer, primarily used for packaging (plastic bags, plastic films, geomembranes and containers including bottles, cups, jars, etc.). , over 100 million tonnes of polyethylene resins are being produced annually, accounting for 34% of the total plastics market. Many kinds of polyethylene are known, with most having the chemical formula (C2H4)''n''. PE is usually a mixture of similar polymers of ethylene, with various values of ''n''. It can be ''low-density'' or ''high-density'' and many variations thereof. Its properties can be modified further by crosslinking or copolymerization. All forms are nontoxic as well as chemically resilient, contributing to polyethylene's popularity as a multi-use plastic. However, polyethylene's chemical resilience also makes it a long-lived and decomposition-resistant pollutant when disposed of improperly. Being a h ...

Galvanization
Galvanization ( also spelled galvanisation) is the process of applying a protective zinc coating to steel or iron, to prevent rusting. The most common method is hot-dip galvanizing, in which the parts are coated by submerging them in a bath of hot, molten zinc. Protective action The zinc coating, when intact, prevents corrosive substances from reaching the underlying iron. It's main function is to act as a sacrificial anode to prevent the iron from rusting by cathodic protection. Zinc is more reactive than iron, so the zinc coating preferentially oxidizes to zinc carbonate, preventing the iron from corroding, even if there are gaps in the zinc coating. Additional electroplating such as a chromate conversion coating may be applied to provide further surface passivation to the substrate material. History and etymology The process is named after the Italian physician, physicist, biologist and philosopher Luigi Galvani (9 September 1737 – 4 December 1798). The earliest kno ...

Autotype (printing)
Halftone is the reprographic technique that simulates continuous tone, continuous-tone imagery through the use of dots, varying either in size or in spacing, thus generating a gradient-like effect.Campbell, Alastair. ''The Designer's Lexicon''. ©2000 Chronicle, San Francisco. "Halftone" can also be used to refer specifically to the image that is produced by this process. Where continuous-tone imagery contains an infinite range of colors or greys, the halftone process reduces visual reproductions to an image that is printed with only one color of ink, in dots of differing size (pulse-width modulation) or spacing (frequency modulation) or both. This reproduction relies on a basic optical illusion: when the halftone dots are small, the human eye interprets the patterned areas as if they were smooth tones. At a microscopic level, developed black-and-white photographic film also consists of only two colors, and not an infinite range of continuous tones. For details, see film grain. ...

Matrix (printing)
In the manufacture of metal type used in letterpress printing, a matrix (from the Latin meaning ''womb'' or ''a female breeding animal'') is the mould used to cast a letter, known as a sort (typesetting), sort. Matrices for printing types were made of copper. However, in printmaking the matrix is whatever is used, with ink, to hold the image that makes up the print, whether a plate in etching and engraving or a woodblock in woodcut. Description In letterpress or "cold metal" typesetting, used from the beginning of printing to the late nineteenth century, the matrix of one letter is inserted into the bottom of an adjustable-width hand mould, the mould is locked and molten type metal is poured into a straight-sided vertical cavity above the matrix. When the metal has cooled and solidified the mould is unlocked and the newly cast metal sort is removed. The matrix can then be reused to produce more copies of the sort.Meggs, Philip B.

Metal Movable Type
Movable type (US English; moveable type in British English) is the system and technology of printing and typography that uses movable Sort (typesetting), components to reproduce the elements of a document (usually individual alphanumeric characters or punctuation marks) usually on the medium of paper. Overview The world's first movable type printing technology for paper books was made of porcelain materials and was invented around 1040 AD in China during the Northern Song dynasty by the inventor Bi Sheng (990–1051). The earliest printed paper money with movable metal type to print the identifying Banknote seal (China), code of the money was made in 1161 during the Song dynasty. In 1193, a book in the Song dynasty documented how to use the copper movable type. The oldest extant book printed with movable metal type, Jikji, was printed in Korea in 1377 during the Goryeo dynasty. The spread of both movable-type systems was, to some degree, limited to primarily East Asia. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ottmar Mergenthaler
Ottmar Mergenthaler (11 May 1854 – 28 October 1899) was a German-American inventor who invented the linotype machine, the first device that could easily and quickly set complete lines of type for use in printing presses. This machine revolutionized the art of printing. Life and career Mergenthaler was born into a German family in Hachtel, Kingdom of Württemberg. He was the third son of a school teacher, Johann Georg Mergenthaler, from Hohenacker near the city of Waiblingen. He was apprenticed to a watchmaker in Bietigheim before immigrating to the United States in 1872 to work with his cousin August Hahl in Washington, D.C. Mergenthaler eventually moved with Hahl's shop to Baltimore, Maryland. In 1878, Mergenthaler became a naturalized citizen of the United States. In 1881, Mergenthaler became Hahl's business partner. Invention of the Linotype In 1876, Mergenthaler was approached by James O. Clephane and his associate Charles T. Moore, who sought a quicker ...
