Cross Platforms Display Calibration and Profiling (MacOs and Windows)

摘要

The monitor is an important part in many digital applications, including graphic design, digital photography and prepress proofing. In fact, designers and prepress personnel rely on their monitor for good color decision for a printed job. The aim of this research is to achieve a consistent color across platform using the same hardware (CPU, monitor, video controller, etc.) In addition, it is to describe the main issue that affects the accuracy of monitor profiles. ICC profiles were generated for a monitor in Windows and MacOS platforms, using GretagMacbeth ProfileMaker Pro version 5.0 and X-Rite MonacoPROFILER 4.8 ICC profiling software. In the laboratory environment, we used a GretagMacbeth Eye-One to calibrate the LCD monitor. An open source library program was then customized and used to read some required and optional tags from all tested monitors profiles. After evaluating the profiles we then used the customized programming code to rebuild a new LUT-based-profile that contains averaged data of the tested tags and applied the profiles in Windows and Mac platforms. The quality of the new customized profile was then tested and evaluated. The results show that there are many factors that affect the quality of monitor profiles, such as the correct calculation of characterized data in LUT tables, accurate loading of the video card gamma tag into video card and show the different between the matrix-based and LUT-based profiles.
