It is a first color space, namely, what color space based on the color of the control.
Color Management Basic concepts and their implementation ( HC printing network With map)
Print Network HC 1 including the original graphic, often after many processing equipment, to get their copy. These devices include input devices, graphics and image processing equipment, output equipment. Because of the digital pre-press graphic information processing system is open, not limited by the use of equipment, materials and process. A variety of brands, types and colors of the color forming characteristic features of the device increases the diversity of the difficulty of accurate color reproduction. Graphic information transfer process in these devices, the inevitable loss of information will have to reproduce the image with the original in terms of color, both level and far from saturation, serious or even make the entire image beyond recognition. To correct and complete copy manuscript, there must be a kind of color conversion and transfer control mechanism, which is color management.
Color management called CMS (Color MangementSystem), it is above all a color space, namely, what color space based on the color of the control. Displays, digital cameras, Scanners Are all working in RGB color space; Printer , Proofer , Print Machines are all work in the CMYK color space, with an image output on these devices, the last of the color effect may be different entirely. This is because they are in different color space's sake, there's differences in color expression.
Color management need to establish a connection with any specific equipment, materials, process independent of the basis of the color space. Currently, color management technology, the color characteristics of the so-called connection space is used CIE1976Lab the color space and color on any device can convert this space to form a "universal" to describe the method, and then match the color conversion . Inside the computer operating system to implement the task of color matching conversion is "color matching module" completed, the reliability of its color change or not, whether the color matches are important.
So, how to achieve the color in the "generic" color space is passed, to achieve non-destructive color or as little as possible losses? This requires that each set of equipment to generate a profile, that is the color profiles. We know that in the presentation and delivery of color, a variety of equipment, materials and process would show different features. In color management, to a device on a high-fidelity color rendering to present in another device, which requires us to understand the color in the color rendering of various features of the device. As has been selected and the device-independent color space, that CIE1976Lab color space, the color characteristics of the performance are: the description of the device value and the "generic" color space, color values of corresponding relations, the correspondence is the color of the device description file.
Color management technology, the most common device description files have three types of color features.
The first is the scanner profiles, which provides Kodak , Agfa, Fuji's standard criteria for the original and the original data, enter the original use of the scanner, scan data and the standard difference between the original data to reflect the characteristics of the scanner;
Second feature is the display file, it provides some software can display color temperature measured, and then generate a color block on the screen, the display of these blocks of color reflect the characteristics of the information;
Third category features document for the printing device, it provides a set of software that the computer generates a graphic that contains hundreds of color blocks, and then the graphic output in the output device, and if the printer on direct proof, press out on the first film, proofing and then printing the image on the output measure that reflects the characteristics of the print device file information.
