主要讨论颜料、荧光增白剂和显白剂对涂布喷墨打印纸白度和打印图像效果的影响。分析了涂布纸的白度与颜料和添加剂的用量之间的关系。打印性能主要用打印图像的色密度、色差和图像的耐光性能来衡量。实验得出,涂布纸的白度与图像的性能有很大的相关性,涂布纸的白度较高时,打印图像的色差较小,色密度较高,耐光性能高。
The effects of pigments, optical brighteners and whiteners on the whiteness of printed inkjet paper and the printed image are discussed. The relationship between the whiteness of the coated paper and the amount of pigment and additive was analyzed. Print performance is mainly measured by the color density of the printed image, color difference and lightfastness of the image. The experimental results show that the whiteness of the coated paper has a great correlation with the image performance. When the whiteness of the coated paper is high, the color difference of the printed image is smaller, the color density is higher, and the light fastness is high.
