Introduction to commonly used color management techniques

(1) Adobe's Photoshop color management system

Adobe's Photoshop color management system is Adobe's most famous image processing software. Photoshop has an irreplaceable position in image processing. At the same time, Adobe also strives to develop Photoshop into a complete color management system. The color management features of Photoshop software are controlled by monitor setup (Monitor Setup), printing ink setup (Printing Inks Setup) and color separation settings.

(2) Apple's ColorSync color management system

Apple's ColorSync color management system is a color management system released by Apple. It uses the ICC standard and uses the Lab color gamut space as the standard reference space. It is a system-level color management software applied under the Mac operating system. It is an open color management system, and users can perform color conversion between different color management systems through the Plug-in module of ColorSync. The ColorSync system includes three components, an ICC standard color description file, color matching method (CMM), and application software interface (API).

(3) Kodak's color management system

Kodak's color management system Kodak is a color management system that supports both PC and Mac platforms. Unlike Apple ColorSync and Adobe Photoshop, Kodak's color management system tends to use a modular approach to color management, and provides several local modules. Combining these modules can form a complete color management system . Kodak color management system generally includes 4 modules of KPCMS, DCP, PICC and PCS100, which can be used separately or combined into a complete color management system.

(4) Color management system of QuarkXPress

The color management window of QuarkXPress provides a different management method. Through the Quark software, you can choose to convert only RGB format objects and images, not CMYK format, and you must specify which ICC characteristic file the monitor uses. Adobe's products can be automatically identified. After version 5, Quark experienced some color glitches, but they did not appear often. If non-TIFF PICT or JPG format files are used, each file will be separated in a different way. It still uses CMYK output device as the final output tool.

The above color management systems are basically based on ICC color management technology. The goal of ICC technology is to create a standard format for color lookup tables-such as characteristic files-mainly for simple conversion between different devices (such as scanners, displays, output devices). The quality of this feature file is uncertain, and it mostly depends on the professional skills of the software developer. Today ICC still appears as a standard for digital proofing. However, further investigation shows that ICC does not achieve good quality and cannot meet the accuracy requirements of the same sheet.

(5) GMG's four-dimensional color conversion technology

The core technology of GMG's color management system is its own research and development, especially printer calibration and four-dimensional color space conversion engine technology (4D).

a. Printer closed-loop calibration technology

In the actual production process, when it is found that the color of the printer changes, it is necessary to calibrate the printer. When using GMG printer closed-loop correction technology, the user only needs to run a simple printer calibration program, the software will follow the steps to perform calibration work, according to the control of the printer inkjet volume to achieve the new print color table color difference value and the initial color difference value Unite. The cyclical and precise method ensures a repetitive and stable printing system.

b. Four-dimensional color conversion technology (4D)

The original and target values ​​of GMG's unique four-dimensional color conversion technology are calculated directly in CMYK (unlike the use of CIELab for color gamut space conversion in the ICC Profile color conversion process), so that the black channel characteristics of the original value data are always maintained very Balanced conversion, which ensures a consistent, high-quality visual image in the target CMYK color space.

After accurate closed-loop color correction, you can also obtain the printed dot expansion rate from the measurement process through the measurement of the printed matter, so as to unify the gain of the printed dot when controlling the printer to simulate the dot proofing, to ensure the safety of the dot proof Color consistency.

Based on the above two technologies, the company has a color management system that runs through the entire printing process:

1. GMG CamFlow-RGB color management 2. GMG FileOut-CMYK color management 3. GMG ColorProof-color proofing 4. GMG DotProof-dot proofing 5. GMG FlexoProof-packaging flexo proofing 6. GMG ProofControl- Color inspection tool 7. GMG InkOptimizer-printing press ink optimization 8. GMG Profile Editor-color editing master
