摘要
通过对ECI2002标准色靶数码打样样张进行实验数据测试、分析得到其色块网点呈色符合平面规律,并建立起不同K值下的CMYK到L*a*b*色彩空间转换方程,应用ΔE☆ab色差公式进行精度检验后,最终得出基于平面理论建立起来的CMYK到L*a*b*色彩空间转换方程是实现数码打样设备色空间转换的有效方法,可为数码打样中色彩管理色空间转换部分的研究提供更加广泛的理论依据。
The proof of ECI2002 standard target was tested and it was found that the colors of batch dot were in conformity with the plane regulation. The conversion equation from CMYK to L^＊a^＊b^＊ was built under different K value, after checking precision using color difference formula. It was proved that it is an efficient method of to build the color space conversion equation between L^＊a^＊b^＊ and CMYK in digital proofing using plane theory, It can provide wider basis for color space conversion in color management of digital proofing.
