以印刷稿中的图像为研究对象,印刷稿的图像质量评价为研究目标,建立了图像质量评价指标的应用流程。 该流程首先扫描印刷稿,再对扫描稿进行图像配准处理,然后嵌入特殊的扫描仪特性文件,再用图像评价指标计算出该图像与原稿之间相应的图像质量指数,从而评价印刷稿中的图像质量。 验证实验表明,提出的应用流程具有相当的合理性和可行性。

Printed images were taken as research object and image quality evaluation as the research motivation. An application process for printed image quality evaluation was established. The printed images were scanned firstly; image registration followed; scanner's special ICC profile was assigned into the scanned image; the quality index of the image we get and the original one was calculated at last. The index was used to evaluate the printed image quality. Verification experiment showed that the process is reasonable and feasible.
