摘要
色貌预测是现代颜色科学领域的基本理论和技术。为了评价低光泽度彩色印刷色谱的色貌,以丽印胶版纸印制的彩色印刷色谱为研究对象,根据颜色科学和心理物理学相关实验,建立其色貌参数样本数据组。采用相对系数R2和差异系数CV等数理统计方法,评价这种印刷色谱中Y-M内页在三种不同的照明光源下色貌的视觉评估结果。实验数据分析表明,在D65、A和TL84三种光源中,人眼在A光源下对颜色的识别能力明显不同于D65和TL84光源;同样在这三种光源中人眼对明度和色调的评估准确度最高,彩度最差。
The prediction of color appearance is the basic theory and technology in modern color science field. To evaluate the color appearance of low-glossiness color printing atlas Liyin offset paper color printing atlas is taken as the experimental samples. Then based on color science and visual psychophysics methods, datasets of the samples＇ color appearance are established. The mathematical statistics methods, correlation coefficient R2 and coefficient of variation Cv, are used to evaluate the visual prediction results of Y-M in this color atlas under three different light sources. The experiment shows that the results are very different between A and the other two kinds of light sources, D65 and TL84. All findings indicate that the assessment of lightness and hue is more accurate than chroma.
