以调幅网点和同心圆网点作为主要研究对象,分析了网点结构对网点呈色特性的影响,应用 Clapper-Yule 颜色预测模型和 Lambert-Beer 法则,解释了同心圆网点高饱和度色彩再现的机理,并通过实验对理论分析进行了验证。 结果表明:网点内部结构的差异会影响色彩再现质量,同心圆网点环形内部结构是影响其印刷呈色的重要因素;同心圆网点的色彩表现力优于调幅网点,特别是在饱和度再现上优势明显。

AM dot and concentric dot were taken as the main study objects. The influence of dot structure on color reproduction was analyzed. The color reproduction mechanism of high saturation concentric dot was analyzed with Clapper-Yule model and the law of Lambert-Beer. Experiments were carried out to prove the correctness of the theoretical analysis. The result showed that internal structure of dot can influence color reproduction, and the internal ring structure of concentric dot is an important factor influencing its color reproduction characteristic; concentric dot is superior to AM dot in color reproduction performance, especially in reproduction of saturation.
