Dalim Tango
Dalim Tango was a color retouching package aimed at the repro and prepress markets. It ran on Silicon Graphics workstations, and was first released in 1993. This retouching package is still available in the DALiM LiTHO program. As of 2013, LiTHO version 7 is available for both Linux and Mac OS X operating systems. Features Tango had tools for retouching, creative painting, image manipulation and "merging" different images. It supported the standard CMYK, RGB, CIELAB and HLS color space, HLS color spaces. Users could also work in a CMYK++ mode, which added special inks to the standard four-color CMYK palette, somewhat similar to the InkSwitch module of Barco Creator. A software densitometer with unlimited sample sites was also included. Tango 2.0 could open TIFF, Scitex CT and Dalim native formats.

Silicon Graphics Workstation
Silicon Graphics, Inc. (stylized as SiliconGraphics before 1999, later rebranded SGI, historically known as Silicon Graphics Computer Systems or SGCS) was an American high-performance computing manufacturer, producing computer hardware and software. Founded in Mountain View, California in November 1981 by James H. Clark, Jim Clark, its initial market was 3D graphics computer workstations, but its products, strategies and market positions developed significantly over time. Early systems were based on the RealityEngine, Geometry Engine that Clark and Marc Hannah had developed at Stanford University, and were derived from Clark's broader background in computer graphics. The Geometry Engine was the first very-large-scale integration (VLSI) implementation of a geometry pipeline, specialized hardware that accelerated the "inner-loop" geometric computations needed to display three-dimensional images. For much of its history, the company focused on 3D imaging and was a major supplier of ... [...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 ...

CIELAB
The CIELAB color space, also referred to as ''L*a*b*'' , is a color space defined by the International Commission on Illumination (abbreviated CIE) in 1976. (Referring to CIELAB as "Lab" without asterisks should be avoided to prevent confusion with Hunter Lab). It expresses color as three values: ''L*'' for perceptual lightness and ''a*'' and ''b*'' for the four unique colors of human vision: red, green, blue and yellow. CIELAB was intended as a perceptually uniform space, where a given numerical change corresponds to a similar perceived change in color. While the LAB space is not truly perceptually uniform, it nevertheless is useful in industry for detecting small differences in color. Like the CIEXYZ space it derives from, CIELAB color space is a device-independent, "standard observer" model. The colors it defines are not relative to any particular device such as a computer monitor or a printer, but instead relate to the CIE standard observer which is an averaging of the ...

HLS Color Space
HSL (for hue, saturation, lightness) and HSV (for hue, saturation, value; also known as HSB, for hue, saturation, brightness) are alternative representations of the RGB color model, designed in the 1970s by computer graphics researchers to more closely align with the way human vision perceives color-making attributes. In these models, colors of each ''hue'' are arranged in a radial slice, around a central axis of neutral colors which ranges from black at the bottom to white at the top. The HSL representation models the way different paints mix together to create color in the real world, with the ''lightness'' dimension resembling the varying amounts of black or white paint in the mixture (e.g. to create "light red", a red pigment can be mixed with white paint; this white paint corresponds to a high "lightness" value in the HSL representation). Fully saturated colors are placed around a circle at a lightness value of ½, with a lightness value of 0 or 1 corresponding to fully bla ...

Barco Creator
Barco Creator was an image manipulation program targeted at the repro and print shop markets. It was developed by Barco Creative Systems a division of the Barco Group and first shown as a prototype at Parigraph in April 1988, then later at Ipex 88"Ipex series tracks image manipulation. (highlights of the 1998 Ipex series of international shows)." Graphic Arts Monthly. Reed Business Information, Inc. (US). 1998. Retrieved November 26, 2008 from HighBeam Research: http://www.highbeam.com/doc/1G1-21201447.html ). Barco Creative Systems together with D.I.S.C. and Aesthedes merged into Barco Graphics. It ran on several generations of Silicon Graphics computers till the late 1990s. Barco Graphics (later Esko) ColorTone for Windows NT is considered its successor. History Until the late 1980s digital retouching required specialized hardware such as the Quantel Paintbox. Barco Creator was one of the first products to run on off-the-shelf SGI workstations instead. Originally targete ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Densitometer
A densitometer is a device that measures the degree of darkness (the optical density) of a photographic or semitransparent material or of a reflecting surface. The densitometer is basically a light source aimed at a photoelectric cell. It determines the density of a sample placed between the light source and the photoelectric cell from differences in the readings. Modern densitometers have the same components, but also have electronic integrated circuitry for better reading. Types *Transmission densitometers that measure transparent materials *A transmission densitometer used to measure transparent surfaces measure color transparencies. Film & transparent substrates are some examples of common transparent surface measures. *Reflection densitometers that measure light reflected from a surface of any state. Photography applications Some are capable of both types of measurements selectable by a switch. They are used in film photography to measure densities of negatives with the swi ...

TIFF
Tag Image File Format, abbreviated TIFF or TIF, is an image file format for storing raster graphics images, popular among graphic artists, the publishing industry, and photographers. TIFF is widely supported by scanning, faxing, word processing, optical character recognition, image manipulation, desktop publishing, and page-layout applications. The format was created by the Aldus Corporation for use in desktop publishing. It published the latest version 6.0 in 1992, subsequently updated with an Adobe Systems copyright after the latter acquired Aldus in 1994. Several Aldus or Adobe technical notes have been published with minor extensions to the format, and several specifications have been based on TIFF 6.0, including TIFF/EP (ISO 12234-2), TIFF/IT (ISO 12639), TIFF-F (RFC 2306) and TIFF-FX (RFC 3949). History TIFF was created as an attempt to get desktop scanner vendors of the mid-1980s to agree on a common scanned image file format, in place of a multitude of proprietary for ...

Barco ColorTone
Barco ColorTone was a stripped-down version of the Barco Creator image manipulation program. It was originally developed for IRIX, and only featured the base "CT-Brix", brush and colour correction modules. An additional "image quality estimator" module, not featured in Creator, was also added. Later it was ported as a standalone program to Windows NT. Esko continued to support it after the Barco Graphics division merged with Purup-Eskofot to form Esko Graphics. Now known as Esko ColorTone, the current 3.0 version also features the optional CT-Brix modules "InkSwitch" and "BlackSmith" in addition to the "FlexoFix" filter. The last version was 7.0 build 70511 released with Esko Software Suite 10. Some time prior to August, 2013 Esko ceased selling the ColorTone program*.

Linotype-Hell DaVinci
Linotype-Hell DaVinci was an image manipulation program targeted at the repro and print shop markets. It originally ran on proprietary hardware, but was later ported to Silicon Graphics workstations. The first version was released in 1993, and it continued to see regular releases until Heidelberg acquired Linotype-Hell in 1997. Heidelberg continued to update the software a few times before it was discontinued in April 2001, but the core engines for trapping and color management were recoded to work on PDF files and were a key contributor to the commercial success of Prinergy, whicbenefittedfrom the Heidelberg-Creo joint venture. Development Hardware DaVinci originally ran on proprietary "Power" workstations with dual 68040 or 88110 processors and several custom ASICs. Later it was ported to SGI IRIX based "Sprint" systems. Optional hardware included a high-speed FDDI interface and a second Ethernet controller. The DaVinci name was the second choice during its development. Int ...

Raster Graphics Editors
A raster graphics editor is a computer program that allows users to create and edit images interactively on the computer screen and save them in one of many raster graphics file formats (also known as bitmap images) such as JPEG, PNG, and GIF. Comparison to vector graphic editors Vector graphics editors are often contrasted with raster graphics editors, yet their capabilities complement each other. The technical difference between vector and raster editors stem from the difference between vector and raster images. Vector graphics are created mathematically, using geometric formulas. Each element is created and manipulated numerically; essentially using Cartesian coordinates for the placement of key points, and then a mathematical algorithm to connect the dots and define the colors. Raster images include digital photos. A raster image is made up of rows and columns of dots, called pixels, and is generally more photo-realistic. This is the standard form for digital cameras; w ...

IRIX Software
IRIX ( ) is a discontinued operating system developed by Silicon Graphics (SGI) to run on the company's proprietary MIPS workstations and servers. It is based on UNIX System V with BSD extensions. In IRIX, SGI originated the XFS file system and the industry-standard OpenGL graphics system. History SGI originated the IRIX name in the 1988 release 3.0 of the operating system for the SGI IRIS 4D series of workstations and servers. Previous releases are identified only by the release number prefixed by "4D1-", such as "4D1-2.2". The "4D1-" prefix continued to be used in official documentation to prefix IRIX release numbers. Prior to the IRIS 4D, SGI bundled the GL2 operating system, based on UniSoft UniPlus System V Unix, and using the proprietary MEX (Multiple EXposure) windowing system. IRIX 3.x is based on UNIX System V Release 3 with 4.3BSD enhancements, and incorporates the 4Sight windowing system, based on NeWS and IRIS GL. SGI's own Extent File System (EFS) replaces the ...
