摘　　要：主要探讨了影响色差评定的因素:光源、视场、背景、照度。光源和视场作为色度计算的主要参数,其选择的不同将会直接影响到色差的数值,进而影响到产品的评定;背景和照度主要影响目视色彩评价中的色彩感受。因此,在工业色差测量中必须要注明测量条件,视觉评判要尽量在标准条件下进行。The factors influencing the evaluation of colors difference of printing and packaging products were discussed. They were illuminant, visual field, background, and luminance. Illuminant and visual field can affect the color difference value directly, while background and luminance affect the visual sense. So the condition such as illuminant and visual field must be given and visual evaluation should be done in standard conditions.

关 键 词：色差 光源 视场 背景 照度
