摘要
研究了不同观察角度对镀铝纸表面色差评价的影响。采用恒常刺激法研究了观察角度对镀铝纸表面颜色视觉感知的影响,以确定镀铝纸上青色墨和品红色墨在标准光源观察箱下的最佳观察评价角度及恰可分辨色差。实验结果表明:不同观察角度下,镀铝纸表面品红色和青色的恰可分辨色差值分别为1.5和1.2,且45°观察角度最适合品红色的颜色视觉评价,而青色则以60°观察角度进行视觉评价最为合适。
Effects of different observation angle on color difference evaluation is researched based on aluminized pa- per. Constant stimulus method is used to analyze the effect of observation angles to color visual evaluation on aluminized paper surface, and then the perceptible color difference and the best observation angle is determined about aluminized pa- pers samples with magenta and cyan color. Experimental results show that aluminized paper sample with magenta and cy- an color is perceived color difference values for 1.5 and 1.2 in different observation angles, respectively. Observation an- gle of 45° is most suitable for visual evaluation of aluminized paper sample with magenta color. Observation angle for 60° is most suitable for visual evaluation of aluminized paper sample with cyan color.
