镭射复合材料表面呈色性能的检测与分析

Research on Measurement of Chromatic Characteristics on Holographic Foil Materials

应用Matlab软件绘制出一种镭射复合原材料以不同入射角、反射角观察时的分光反射率分布曲线以及xy色度图、LAB色度图 ,直观分析了该材料表面的呈色性能 ,即镭射复合材料上固定的点在不同角度下呈现不同的颜色和较高的光泽度。并进一步探讨了其印刷产品色差检测的研究方法。

Holographic foil materials are widely used in packaging printing products. The chromatic characteristic of a kind of holographic foil materials was analyzed. By using Matlab 6.1, the spectral reflectivity curves, xy chromatic diagram and LAB chromatic diagram of the holographic foil material to different angle of incidence or reflection were drawn, which obviously show that the color was very different in different observing angles. The research method of printing quality control on such materials was discussed.
