Diatype (machine)
A Diatype is a manual "typesetter machine" used for the phototypesetting of texts, printing them on a light-sensitive film, that can be used in different environments of the graphic arts industry. Operation The light-sensitive film is fitted on a drum and inserted in the machine. The machine must be prepared by fitting the appropriate disk which should contain all the required fonts, these fonts are transparent on black support. Then the character that is wanted to be printed is selected by rotating a crowbar and then exposed to the light-sensitive film by means of a suitable lamp . This way, characters are printed, in a one by one basis, until the start of a new line of text is needed, then to make the film advance, the drum is rotated a few millimeters by means of a crank designed for this purpose, and the procedure continues Once all the composition of a complete text it has been printed, the light-sensitive film is withdrawn from the drum, taken to reveal it in the dark r ...

Diatype Typesetter
In sociolinguistics, a register is a variety of language used for a particular purpose or in a particular communicative situation. For example, when speaking officially or in a public setting, an English speaker may be more likely to follow prescriptive norms for formal usage than in a casual setting, for example, by pronouncing words ending in ''-ing'' with a velar nasal instead of an alveolar nasal (e.g., ''walking'' rather than ''walkin'''), choosing words that are considered more "formal" (such as ''father'' vs. ''dad'' or ''child'' vs. ''kid''), and refraining from using words considered nonstandard, such as '' ain't'' and ''y'all''. As with other types of language variation, there tends to be a spectrum of registers rather than a discrete set of obviously distinct varieties—numerous registers can be identified, with no clear boundaries between them. Discourse categorisation is a complex problem, and even in the general definition of ''register'' given above (language va ...

Phototypesetting
Phototypesetting is a method of setting type. It uses photography to make columns of type on a scroll of photographic paper. It has been made obsolete by the popularity of the personal computer and desktop publishing (digital typesetting). The first phototypesetters quickly project light through a film negative of an individual character in a font, then through a lens that magnifies or reduces the size of the character onto photographic paper or film, which is collected on a spool in a light-proof canister. The paper or film is then fed into a processor, a machine that pulls the paper or film strip through two or three baths of chemicals, from which it emerges ready for paste-up or film make-up. Later phototypesetting machines used other methods, such as displaying a digitised character on a CRT screen. Phototypesetting offered numerous advantages over metal type, including the lack of need to keep heavy metal type and matrices in stock, the ability to use a much wider ran ...

Text (literary Theory)
In literary theory, a text is any object that can be "read", whether this object is a work of literature, a street sign, an arrangement of buildings on a city block, or styles of clothing. It is a coherent set of signs that transmits some kind of informative message. This set of signs is considered in terms of the informative message's ''content'', rather than in terms of its physical form or the medium in which it is represented. Within the field of literary criticism, "text" also refers to the original information content of a particular piece of writing; that is, the "text" of a work is that primal symbolic arrangement of letters as originally composed, apart from later alterations, deterioration, commentary, translations, paratext, etc. Therefore, when literary criticism is concerned with the determination of a "text", it is concerned with the distinguishing of the original information content from whatever has been added to or subtracted from that content as it appear ...

Darkroom
A darkroom is used to process photographic film, to make prints and to carry out other associated tasks. It is a room that can be made completely dark to allow the processing of the light-sensitive photographic materials, including film and photographic paper. Various equipment is used in the darkroom, including an enlarger, baths containing chemicals, and running water. Darkrooms have been used since the inception of photography in the early 19th century. Darkrooms have many various manifestations, from the elaborate space used by Ansel Adams to a retooled ambulance wagon used by Timothy H. O'Sullivan. From the initial development of the film to the creation of prints, the darkroom process allows complete control over the medium. Due to the popularity of color photography and complexity of processing color film (''see C-41 process'') and printing color photographs and also to the rise, first of instant photography technology and later digital photography, darkrooms are decr ...

Contact Copier
A contact copier (also known as contact printer), is a device used to copy an image by illuminating a film negative with the image in direct contact with a photosensitive surface (film, paper, plate, etc.). The more common processes are negative, where clear areas in the original produce an opaque or hardened photosensitive surface, but positive processes are available. The light source is usually an actinic bulb internal or external to the device Commercial contact printers or process cameras usually use a pump-operated vacuum frame where the original and the photosensitive surface are pressed together against a flat glass by a grooved rubber mat connected to the vacuum source. A timer-controlled mercury vapor ( arc or fluorescent) light source is on the other side of the glass. Uses The contact copying process was used in the early days of photography and sunlight-exposed blueprints; it is still used in amateur photography, silkscreen printing, offset printing, and photochem ...

Desktop Publishing
Desktop publishing (DTP) is the creation of documents using page layout software on a personal ("desktop") computer. It was first used almost exclusively for print publications, but now it also assists in the creation of various forms of online content. Desktop publishing software can generate layouts and produce typographic-quality text and images comparable to traditional typography and printing. Desktop publishing is also the main reference for digital typography. This technology allows individuals, businesses, and other organizations to self-publish a wide variety of content, from menus to magazines to books, without the expense of commercial printing. Desktop publishing often requires the use of a personal computer and WYSIWYG page layout software to create documents for either large-scale publishing or small-scale local multifunction peripheral output and distribution – although a non-WYSIWYG system such as LaTeX could also be used for the creation of highly structure ...

Word Processor
A word processor (WP) is a device or computer program that provides for input, editing, formatting, and output of text, often with some additional features. Early word processors were stand-alone devices dedicated to the function, but current word processors are word processor programs running on general purpose computers. The functions of a word processor program fall somewhere between those of a simple text editor and a fully functioned desktop publishing program. However, the distinctions between these three have changed over time and were unclear after 2010. Background Word processors did not develop ''out'' of computer technology. Rather, they evolved from mechanical machines and only later did they merge with the computer field. The history of word processing is the story of the gradual automation of the physical aspects of writing and editing, and then to the refinement of the technology to make it available to corporations and Individuals. The term ''word proces ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heliographic Copier
A heliographic copier or heliographic duplicator is an apparatus used in the world of reprography for making contact prints on paper from original drawings made with that purpose on tracing paper, parchment paper or any other transparent or translucent material using different procedures. In general terms some type of ''heliographic copier'' is used for making: Hectographic prints, Ferrogallic prints, Gel-lithographs or Silver halide prints. All of them, until a certain size, can be achieved using a contact printer with an appropriate lamp (ultraviolet, etc...) but for big engineering and architectural plans, the ''heliographic copiers'' used with the cyanotype and the diazotype technologies, are of the roller type, which makes them completely different from contact printers. In the "argot" of engineers, architects and designers, the resulting plan copies coming from any type of '' heliographic copier'' no matter they were either blue or white, were traditionally called blueprints ...

Offset Printing
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 Megg ...

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 Will ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Duplicating Machines
Duplicating machines were the predecessors of modern document-reproduction technology. They have now been replaced by digital duplicators, scanners, laser printers and photocopiers, but for many years they were the primary means of reproducing documents for limited-run distribution. The duplicator was pioneered by Thomas Edison and David Gestetner, with Gestetner dominating the market up until the late 1990s. Like the typewriter, these machines were products of the second phase of the industrial revolution which started near the end of the 19th century (also called the Second Industrial Revolution). This second phase brought to mass markets technologies like the small electric motors and the products of industrial chemistry without which the duplicating machines would not have been economical. By bringing greatly increased quantities of paperwork to daily life, the duplicating machine and the typewriter gradually changed the forms of the office desk and transformed the nature of ...

Hectograph
The hectograph, gelatin duplicator or jellygraph is a printing process that involves transfer of an original, prepared with special inks, to a pan of gelatin or a gelatin pad pulled tight on a metal frame. While the original use of the technology has diminished, it has recently been revived for use in the art world. The hectograph has been modernized and made practical for anyone to use. Process The special aniline dyes for making the master image came in the form of ink or in pens, pencils, carbon paper and even typewriter ribbon. Hectograph pencils and pens are sometimes still available. Various other inks have been found usable to varying degrees in the process; master sheets for spirit duplicators have also been pressed into service. Unlike a spirit duplicator master, a hectograph master is not a mirror image. Thus, when using a spirit duplicator master with a hectograph, one writes on the back of the purple sheet, using it like carbon paper to produce an image on the wh ...
