【摘要】 介绍了颜色空间转换中,三维空间L*a*b*与四维空间C′M′Y′K的转换途径、K值产生的原理以及K值对三原色的影响。讨论了使用灰成分替代(GCR)确定K值,通过灰平衡数据得出C′M′Y′值,以及建立CMY与C′M′Y′K对应关系的方法,最终完成L*a*b*与C′M′Y′K颜色空间的转换。更多还原

【Abstract】 The conversion between L*a*b* and C′M′Y′K is a transform from three color space to four color space.The methods of confirming the amount of black based on the Gray Component Replacement(GCR) theory were analyzed,the data of gray balance and the amount of C′M′Y′ were obtained.And the one to one correspondence between CMY and C′M′Y′K was established,so that the CMY was conversed to C′M′Y′K and the conversion between L*a*b* and C′M′Y′K was carried out.更多还原
