摘　　要：数字印刷相比传统印刷而言更容易产生噪声感图像,为此有必要测量和评价数字印刷品的噪声特性。本文在分析ISO13660标准定义的颗粒度和斑点测量方法的基础上,说明采用L测量数据计算噪声的必要性,并建议选择基于视觉滤波的测量系统。Comparison with traditional printing, noise images will be produced by digital printing so easily as to measure and evaluate noise property in digital prints. In this paper, methods of graininess and mottle measuring defined by the ISO 13660 standard were analyzed to prove the necessity using measured L data to compute noise and selecting a measuring system based on VTF filtering.
