中文摘要:

      为了建立一套客观的印刷品质量评价流程，以保证印刷质量，针对数字原稿，扩展了传统评价方法，考虑了承印物的影响因素，对主观评价加以客观化，并精炼了客观评价的项目指标，最后进行了综合评价。根据国家标准及调研统计后得到的标准，设定了各个评价方法中各参数的等级标准，并设定了评价分值，用定量的结果评价图像质量的好坏。将该流程应用到了几种不同类型的数字彩色图像，综合评价分数表明，该评测的标准图像为A等印刷品。

英文摘要:

      An objective image quality evaluation process was established to ensure good printing quality. The traditional evaluation methods were expanded which considered substrate factors. The subjective evaluation was objectified, and the project indicators of objective evaluation were refined. The comprehensive evaluation was eventually conducted. The grading standards of parameters for each evaluation method were determined according to national standards and standards from research statistics, and score was set to evaluate the performance of image quality by quantitative results. The evaluation process was applied on some different types of digital color image, and comprehensive scores show that the standard image is the print of grade A.
