Adobe Photoshop Color Management System As Adobe's most famous image processing software, Photoshop has its irreplaceable position in image processing. At the same time, Adobe is trying to develop Photoshop into a complete color management system. The color management features of Photoshop software are controlled by Monitor Setup, Printing Inks Setup and color separation Settings.

In order for the color that the user sees on the screen to match the color of the output proof as closely as possible, the user's system must be corrected first. The accurate color workflow must begin with the display correction and display setup. "Monitor Setup" includes two parts: monitor calibration and monitor setup. In the display to display type, phosphorescent powder, color temperature and other numbers for correct selection, so that in the image for color mode conversion, can be set according to the above parameters for the correct color conversion.

The basic purpose of the printing ink setup is for Photoshop to provide information about the ink, paper, and printing machine used in the final printing. Different paper on ink absorption and dot expansion is different, different ink color, different printing methods of dot expansion rate is not the same. Therefore, these parameters need to be set in "Printing Inks Setup". After obtaining the basic information from the RGB image data and the display data obtained in the "Monitor Setup", the color mode conversion can be completed according to the characteristics of the final printing conditions.

The most important part of color separation is the determination of the amount of black plate. In theory, color separation from one RGB value can produce multiple CMYK values, and the final printing effect should be the same. However, due to the amount of ink received by different printing paper and the characteristics of different printing machinery, the theoretical possibility can not be realized, so it is necessary to set the type of color separation, the amount of black plate and the percentage of total printing dot accordingly.

ColorSync is a color management system released by Apple Inc. It adopts ICC standard and takes Lab color space as the standard reference space. ColorSync is a system-level color management software applied in Mac operating system. It is an open color management system that allows users to switch colors between different color management systems through ColorSync's Plug-in module. The ColorSync system consists of three components, an ICC standard color description file, color matching method (CMM), and application software interface (API).

The device description file defines the color characteristics of the device. This information enables you to obtain the color range that the device can display, capture, and reproduce. When ColorSync is used to create a file, a Profile file is stored in the file. In this way, when an image with the ColorSync description file is processed on another device, ColorSync will perform color space matching by comparing the characteristics of the device and the characteristics of the display. To get the best color effect.

Color matching is the core part of ColorSync, which realizes the conversion of different color Spaces. More importantly, ColorSync's color transfer mode uses Linotype Hell's high-quality color matching technology, allowing users to work with colors outside the gamut using better compression methods.

From image scanning to final reproduction, the same image color will have a different appearance due to different application performance of color. In order to be able to grasp the accurate color at all times in the work, it is necessary to effectively match the color of these applications. Color matching can be done through ColorSync application software, so as to achieve the purpose of consistency.

Kodak's Color Management System Kodak is a color management system that supports both PC and Mac platforms. Unlike Apple ColorSync and Adobe's Photoshop, Kodak's color management system tends to take a modular approach to color management and offers several localized modules that can be combined to create a complete color management system. And it has color management for the Photo CD image input process.

Kodak color management system generally includes KPCMS, DCP, PICC and PCS100 4 modules, which can be used separately or combined into a complete color management system.

The KPCMS module (Kodak Precision Color Management System) provides plenty of device description files in the standard ICC format. Its input devices include RGB image sources and CMYK image sources, and its output devices include printers and proof machines. However, it has great limitations because it cannot edit the device description file.

DCP module (Device Color Description File Startup Package) is a software package designed to provide display and output color correction for PhotoCD images. When opening PhotoCD images, the user is required to select two device description files. The input device description file is a PhotoCD device description file. The output device description file can be a display description file or a color proof machine description file. The PICC module (Precision Input Color Characterization) provides a standard scanner utility that enhances the capabilities of the DCP.

For advanced image processing and scanning applications, Kodak offers the PCS100 module to speed up the color conversion process for Photo CD and Prophoto CD images. With the PCS100 module, direct links between various devices can be generated to skip the intermediate conversion process to the CIE color space, saving the time of each conversion as well as color loss during conversion.
