Desktop Color Separations
Desktop Colour Separation (DCS) is an enhanced Encapsulated PostScript file format that was introduced by Quark, Inc. It is now primarily used for specialised graphics work particularly images that use multiple channels, e.g. when applying different spot colours to each part of a greyscale image. Format In DCS a CMYK graphic is separated into five files; a main file and four pre-separation files, one for each CMYK process colour. The main file contains an indication of which separation files are needed and where to find them, together with a composite image information which is used to print a composite of the image. Operation When output to a PostScript printer Printer may refer to: Technology * Printer (publishing), a person or a company * Printer (computing), a hardware device * Optical printer for motion picture films People * Nariman Printer ( fl. c. 1940), Indian journalist and activist * Jame ..., the printer driver reads the information in the main file and assigns ...

Encapsulated PostScript
Encapsulated PostScript (EPS) is a Document Structuring Convention (DSC) conforming PostScript document format usable as a graphics file format. The format was developed as early as 1987 by John Warnock and Chuck Geschke, the founders of Adobe, together with Aldus. The basis of early versions of the Adobe Illustrator Artwork file format is formed by EPS together with the DSC Open Structuring Conventions. EPS files are more-or-less self-contained, reasonably predictable, PostScript documents that describe an image or drawing and can be placed within another PostScript document. An EPS file is essentially a PostScript program, saved as a single file that includes a low-resolution preview "encapsulated" within it, allowing some programs to display a preview on the screen. An EPS file contains a '' BoundingBox'' DSC comment, describing the rectangle containing the image described by the EPS file. Applications can use this information to lay out the page, even if they are unable to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
File Format
A file format is a standard way that information is encoded for storage in a computer file. It specifies how bits are used to encode information in a digital storage medium. File formats may be either proprietary or free. Some file formats are designed for very particular types of data: PNG files, for example, store bitmapped images using lossless data compression. Other file formats, however, are designed for storage of several different types of data: the Ogg format can act as a container for different types of multimedia including any combination of audio and video, with or without text (such as subtitles), and metadata. A text file can contain any stream of characters, including possible control characters, and is encoded in one of various character encoding schemes. Some file formats, such as HTML, scalable vector graphics, and the source code of computer software are text files with defined syntaxes that allow them to be used for specific purposes.

Quark, Inc
Quark Software Inc. (founded 1981 in Denver, Colorado, USA) is a privately owned software company which specializes in enterprise publishing software for automating the production of customer communications. The company's original goal was to "create software that would be the platform for publishing", just as quarks are the basis for all matter. The company is best known for its desktop page layout and design software, QuarkXPress, although this has now become secondary to its other products and services. History Quark was founded with $2,000 in 1981 in Denver, Colorado, U.S. Between 1981 and 1985, their primary products were Word Juggler and Catalyst. Word Juggler was the first word processor on the Apple III. Catalyst was a program that was distributed bundled with the Apple IIe, and allowed users to run floppy disk-based applications from their hard drive. They also attempted a product line called "Quark Peripherals", but the market for storage devices at the time resulted i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
CMYK
The CMYK color model (also known as process color, or four color) is a subtractive color model, based on the CMY color model, used in color printing, and is also used to describe the printing process itself. The abbreviation ''CMYK'' refers to the four ink plates used: cyan, magenta, yellow, and key (black). The CMYK model works by partially or entirely masking colors on a lighter, usually white, background. The ink reduces the light that would otherwise be reflected. Such a model is called ''subtractive'' because inks "subtract" the colors red, green and blue from white light. White light minus red leaves cyan, white light minus green leaves magenta, and white light minus blue leaves yellow. In additive color models, such as RGB, white is the "additive" combination of all primary colored lights, black is the absence of light. In the CMYK model, it is the opposite: white is the natural color of the paper or other background, black results from a full combination of colo ...

PostScript
PostScript (PS) is a page description language in the electronic publishing and desktop publishing realm. It is a dynamically typed, concatenative programming language. It was created at Adobe Systems by John Warnock, Charles Geschke, Doug Brotz, Ed Taft and Bill Paxton from 1982 to 1984. History The concepts of the PostScript language were seeded in 1976 by John Gaffney at Evans & Sutherland, a computer graphics company. At that time Gaffney and John Warnock were developing an interpreter for a large three-dimensional graphics database of New York Harbor. Concurrently, researchers at Xerox PARC had developed the first laser printer and had recognized the need for a standard means of defining page images. In 1975-76 Bob Sproull and William Newman developed the Press format, which was eventually used in the Xerox Star system to drive laser printers. But Press, a data format rather than a language, lacked flexibility, and PARC mounted the Interpress effort to create a succ ...

Printer (computing)
In computing, a printer is a peripheral machine which makes a persistent representation of graphics or text, usually on paper. While most output is human-readable, bar code printers are an example of an expanded use for printers. Different types of printers include 3D printers, inkjet printers, laser printers, and thermal printers. History The first computer printer designed was a mechanically driven apparatus by Charles Babbage for his difference engine in the 19th century; however, his mechanical printer design was not built until 2000. The first patented printing mechanism for applying a marking medium to a recording medium or more particularly an electrostatic inking apparatus and a method for electrostatically depositing ink on controlled areas of a receiving medium, was in 1962 by C. R. Winston, Teletype Corporation, using continuous inkjet printing. The ink was a red stamp-pad ink manufactured by Phillips Process Company of Rochester, NY under the name Clear Prin ...
