软打样显示器的显色性能研究

显示器的显色性能会随着使用时间以及环境条件的改变而变化。本文以显示器显色性能为研究对象,设计一套系统的显示器性能测试实验,采用正交试验分析色温、亮度和Gamma值对EIZO CG247和Dell P2714H显示器显色能力的影响,为显示器确定合适的校准条件。此外,还对显示器的空间均匀性和时间稳定性进行了对比测试,以更好地将显示器应用于软打样。实验结果表明:对于两台显示器,在三个校准参数中,都表现为色温对显示器呈色的影响最大,Gamma值次之,亮度最小;两显示器的最佳显色参数都为色温6 500 K,亮度120cd/m~2,Gamma值2.2,但是Dell P2714H的平均色差1.06大于EIZO CG247显示器的0.64;并且两显示器在空间均匀性和时间稳定性方面表现相接近。

Color performance of monitor used in soft proofing

Color performance of the monitor varies with time and environmental conditions. In this paper, the color performance of the monitor is chosen as the research object, and a systematic test is designed. An orthogonal test is used to analyse that how the color temperature, brightness and Gamma value affect the color ability of EIZO ColorEdge color CG247 and Dell P2714H, and determine a best calibration conditions for them. Furthermore, we test the spatial uniformity and time stability of the monitors, which is a guidance on how to make better use of the monitors in soft proofing. Experimental results show that the color temperature has the biggest influence on both of the monitors, Gamma value is next, brightness is minimum. The best color rendering condition of the displays are equal to color temperature 6 500 K, brightness 120 cd/m² and Gamma value 2.2, but the average color difference of Dell P2714H is 1.06, which is higher than that of EIZO CG247. Besides, there are similar spatial homogeneity and time stability on them.
