【摘要】 屏幕软打样技术是近几年刚刚兴起的一项新技术,它不仅取决于设备还取决于设备的色彩管理程度。本文通过实验对屏幕软打样效果进行了测量和主观的评价,对比了显示颜色与硬拷贝样张的色差,并通过目视评价对软打样的效果进行了主观目视评价。实验结果显示,经过严格色彩管理的显示器和输出设备,可以达到印刷软打样的效果,显示和硬拷贝间的平均色差可以达到⊿Eab=3.5,较大色差主要由超色域的颜色造成,大部分颜色的显示效果可以满足印刷的一般要求。文章还对主观评价的色差等级与CIELAB色差的相关性进行了讨论。更多还原

【Abstract】 Soft proofing is a brand new technology in recent years. It depends not only on the display and also on the color management. The effect of soft proof is evaluated through the experiments both by direct color measurement and subjective evaluation. The experiment results show that LCD can be used for printing soft proofing as long as it is color managed. The color differences between display and hardcopy are practical low, the mean ⊿Eab=3.5. Most large differences are caused by out-of-gamut colors while most color differences are small enough for printing industry. The relationship between measured color difference and that of subjective evaluated is also discussed in the paper.更多还原
