摘要
视场是影响颜色测量的重要因素,视场选用的不同,测量结果也不相同。在国家标准中对于色彩测量视场的选用规定比较混乱。分析了2°和10°视场的视觉生理特点,分别比较了同一颜色在不同视场下以及印刷样品色与复制色在不同视场下的评价差异,结果表明视场的选择不同会明显影响评价结果。建议印刷色彩测量统一采用2°视场。
Visual field is an important parameter influencing color measurement. The result of color measurement is different if different visual field is used. In Chinese national standard it is not uniform for the visual field selection. This paper analyzed the visual physiological characteristic of 2 and 10 degree visu- al fields. The color difference of one color in different visual field was calculated. Also color difference of a pair of print colors was calculated. The result showed that the selection of visual fields can affect the evaluation evidently. Therefore 2-deg visual field is recommended in printing color measurement.
