摘要
为了有效评价低水平荧光纸张D65荧光亮度检测结果的精密度,给同行企业提供参考数据或参考方法,本研究基于GB/T7974-2013中等水平荧光纸张D65荧光亮度检测结果精密度要求的前提下,对多个低水平荧光纸张及印刷成品进行平衡均匀水平实验[1]并对实验的检测结果进行统计分析以求建立一种低水平荧光纸张D65荧光亮度检测结果精密度的评价方法。结果表明:受各样本测试水平差异影响D65荧光亮度数据结果的变异系数散乱无章、无规律可循,表明变异系数法不适用于低水平荧光纸张D65荧光亮度检测结果精密度的评价;但无论是单样本标准偏差还是单组合并样本标准偏差或总体合并样本标准偏差数值均≤0.02%,且呈正态分布状,表明标准偏差法适用于低水平荧光纸张D65荧光亮度检测结果精密度的评价,约定低水平荧光纸张D65荧光亮度检测结果的重复性标准偏差≤0.02%是可行的。
In order to effectively evaluate the precision of fluorescence brightness test results of low level fluorescent paper D65 and provide reference for peer enterprises,this study is based on the premise of the precision requirements of fluorescence brightness test results of medium-level fluorescent paper D65 of GB/T 7974-2013.Several low level fluorescent paper and printing products were tested for balanced and uniform level,and the test results were statistically analyzed in order to establish a precision evaluation method for the fluorescence brightness detection of low-level fluorescent paper D65.The results show that the coefficient of variation of D65 fluorescence luminance data results affected by the differences in test levels of each sample is scattered and rule-free,indicating that the coefficient of variation method is not suitable for evaluating the precision of D65 fluorescence brightness results of low-level fluorescent paper.However,both the standard deviation of a single sample,the standard deviation of a single group of pooled samples or the standard deviation of the overall pooled samples are less than or equal to 0.02%,and the value is normally distributed,indicating that the standard deviation method is suitable for the evaluation of the precision of fluorescence brightness detection results of low level fluorescent paper D65.It is feasible to agree that the repeatability standard deviation of D65 fluorescence brightness test results of low level fluorescent paper should be less than 0.02%.
