| 目的 针对金银卡纸表面因具有强烈的镜面反射作用且印刷适性较差的缺点，研究金银卡纸镜面反射对印刷品颜色的质量控制。方法 试验分析金银卡纸印刷镜面反射作用对印品明度值的影响，用曲线拟合的方法找出包含和不包含镜面反射作用测出的明度值之间的关系。结果 经过检验分析，SCE条件下的测量数据相对于SCI明度偏小，这是因为SCE测量模式中，镜面反射光被排除在外面，只测量了漫射光。从青色的线性拟合图来看，所得线性拟合图大致为一条斜率为45°的直线。结论 包含和不包含镜面反射明度值这2组数据之间存在数学关系，在实际应用中，可以考虑使用明度差这种线性关系来作为金银卡纸颜色控制和评价的依据。 |

| The work aims to study the effects of gold-silver foil paper specular reflection on the control over the color quality of printing matters, regarding that the gold-silver foil paper surface has such shortcomings as strong specular reflection effect and poor printability. The effects of gold-silver foil paper specular reflection on the lightness of printing matters were tested and analyzed. The relationship between the measured lightness including specular reflection effect and that without specular reflection effect was found out in curve fitting method. After inspection and analysis, with respect to SCI lightness, the measured data under the condition of SCE was too small. This was because the specular reflection light was excluded in the SCE measurement mode and only the diffused light was measured. From the linear fitting chart of the blue, the linear fitting chart was basically a straight line with a slope of 45°. There is a mathematical relationship between the group of data containing the specular reflection lightness and that containing no specular reflection lightness. In practical application, this linear relation of lightness difference can be considered as the basis for color control and evaluation in gold-silver foil paper. |
