摘　　要：为了准确、稳定地测量分析光柱镭射纸张及其印刷品的颜色,在分析了纸张微观结构的基础上,选用积分球式分光光度计,在纸张(或印刷品)的不同光柱周期内进行采样,同时在纸张(或印刷品)固定位置处旋转不同角度采样。将采集到的数据进行数学统计分析,建立了两种光柱镭射纸和印刷品的颜色色度值测量和色差计算方法。与现有方法相比,该测量方法在提高了工作效率的同时,也较大地提高了测量精度。该方法可为包装印刷企业的纸张、印刷品质量检测提供高效且客观的评价手段。In order to measure and analyze the color of holographic paper and its printings with light pillars accurately and stably, the integrating sphere spectrophotometer is selected to collect colorimetric values within different periods of light pillars and different angles in fixed position of holographic paper （or printings） based on analyzing the microstructure of paper. The collected values are analyzed to build up two color measurement and analysis methods for holographic papers and printings. Compared with the existing methods, the measurement methods not only improve the working efficiency, but also greatly improve the accuracy of the measurement. Those methods can provide an efficient and objective evaluation way for the quality inspection of packaging and printing enterprises.
