摘要
通过测量三原色油墨印刷在纸上的光谱数据计算印刷品颜色 ,找出原色油墨、油墨二次叠印色之间的光谱数据关系 ,从而分析了印刷后所形成的颜色 ,发现网点扩大量不仅是网点面积的函数 ,而且随波长变化 ;计算结果还反映出油墨叠印的印刷适性。
The color of prints is calculated by means of measuring their spectral reflectance in order to find the relationship between primary inks, secondary inks and their spectral reflectance. After analyzing the printed colors, we have found that the dot gain of prints is not only the function of dot area,but also the function of wave length. The calculation results also reflect the printability of the tapped ink.
