中文摘要:
      加网线数的不同对数字印刷品空间非均匀性质量会产生较大影响,通过空间非均匀性质量属性及检测设备介绍、质量属性算法说明、检测等过程,得到了 ISO 13660 中规定的测试色块的颗粒度、斑点、空白和噪声功率谱。 分别针对同一加网线数不同网点面积率和不同加网线数同一网点面积率两种情况,分析了数据形成原因,并将测试结果与主观判断进行了对比,结果表明,适当提高加网线数可改变数字印刷品空间非均匀性质量。
英文摘要:
      Screen line number has a great impact on digital printing quality of space non-uniformity. The quality attributes of space non-uniformity, testing equipment, algorithm of quality attribute, and testing process were introduced. The test blocks's granularity, mottle, blank, and noise power spectrum specified in the ISO 13660 were obtained. The situations of the same screen line number with different dot area rate and the different screen line number with the same dot area rate were analyzed for the causes of data formation. The test result was compared with subjective judgments. The result showed that increasing screen line number can improve the digital printing quality of space non -uniformity.
