摘要 对印在有光泽的铜版纸上的9个颜色中心、共216种颜色色样进行了视觉评价和客观测量,得出了每种颜色中心的色差的可接受阈值;然后,应用视觉评价标准确定了可用于CIE94、CMC和CIE2000中的最佳l∶c加权系数,并将ΔE94(l∶c)、ΔEcmc(l∶c)、DE2000(l∶c)与ΔEab进行了比较。 An experiment will be done with 9 color centers(216 color samples) and 20 observers to find out the mean of acceptability threshold of each color difference, and visual scale result is used to improve color difference by optimum l : c weighting. The CIE94,CMC and CIE2000 color difference equations were used, △E94, △Ecmc, DE2000 were compared with △Eab.
