摘要
利用 CIE1 976L AB均匀颜色空间的明度公式推导出网点面积与明度感觉的关系 ,从理论上分析并用实验证明出眼睛对图像暗调区域的网点面积变化更敏感 。
The relationship between dot area of printed products and perceived lightness is established based on the CIE 1976 LAB formula The results, which are proved by experiment, show that the lightness is more sensitive to eyes in shadow area than in high light area, so that image reproduction in shadow area is more important
