With the development of computers and peripheral equipment, color desktop appeared, from the image input device, displays the final output methods are becoming more diverse. High resolution Scanners , Digital cameras, color Printer And the market for the short version of the application of digital color printing press has been very common. The type of manuscript from traditional slides, negatives, Fan Shegao developed to photoCD CD-ROM. Used for image processing computer and monitor are different. In addition to adapt to various needs of the growing color output devices, such as color ink-jet printers, thermal wax printers, dye-sublimation printers. Internet gave the appearance of the output image opens a new field. As the color image processing system is an open system, the composition of the flexible system, that is, you can use production scanners Party, Party of the monitors, Party C production imagesetters, printers and so on. Equipment of different manufacturers combined into a system, how the original input from the scanner to the color proofing and to maintain consistency in product output, the image color quality control is essential. First, the essence of color management and task Essence of color management system in the desktop publishing accurate transfer of color control and management, to achieve the perfect color reproduction, color management can make color reproduction and color reproduction with the use of the device-independent, that is the same color data, using any system output, would be the same color effects. In the production process all the hardware devices (scanner, monitor, printer, laser illuminators, printers and other output devices) the interpretation and definition of color in different ways, in different types of conversion of color information between devices prone to error, can not guarantee that the exchange between the system File Color consistency. Color Management's main task is to resolve images in various color space conversion on the data, so that the image color distortion in the entire process of production minimum. The basic idea is: choose a device-independent reference color space, then the whole system to characterize the various devices described, the final color space in all the equipment set up to determine the correspondence. Second, color management, content Color management including equipment calibration, characterization, color conversion. Equipment calibration is a prerequisite to ensure the system work, but can not guarantee consistent image and original, but to see whether the device is designed to achieve the original target; device characteristics is described by the color of different skills and equipment presented by the color range description; color conversion is in the same conditions, a device color space conversion to another device's color space, in a different color space mapping between the color maps. Characterization is the use of digital methods to scanners, monitors, color printers, color ink and other media detailed description of the color performance out of the table with the appropriate color system to describe the media's color space. Characterization is to measure and confirm the input and output devices color copy color set domain or a way to define the color gamut (ColorGamut), established by the characterization of the description after the color range of equipment called the device color data Description File (Profile), Profile factory equipment manufacturers usually provide, and sometimes can also be used with certain tools (such as the American LightSource company Colorton color measurement device) and the corresponding color Management Software (Such as Haier's Printopen and Scanopen, etc.) to establish their own Pro-file. Color conversion is based on different color-one correspondence between the different color space mapping, the color of a device color space conversion to another known condition, the color space to go. As the output device color gamut than the original general, scanners and monitors the colorimetric color gamut is small, it needs to be compressed original color gamut in the color forming domain into the output device. First of all to get from the scanner RGB color information into a device-independent CIE-Lab color space, and then the next device ICCProfile, the CIE-Lab color space conversion color space for the equipment itself. As the CIE-Lab color space with contains extensive color gamut color space, so you will not lose color quality.
