标准摘要
[中文适用范围]： 本国际标准： ——规定了邮件上二维条形码符号形式的数字邮资标记印刷质量属性的测量方法; ——规定了对这些测量结果进行分级并得出总体符号的方法质量等级作为评估数字邮资标记可读性的指南; ——提供印刷指南，并提供有关偏离高等级的可能原因的信息，以帮助用户采取适当的纠正措施; ——定义评估印刷的测试程序用于生产数字邮资标记的系统。 这些规定适用于数字邮资标记块，因为它们在汇给邮政运营商时出现在完全制作的邮件上，包括除打印本身之外的操作所产生的影响其在邮件处理系统中的外观的特征（覆盖、插入透明窗口）信封、贴有数字邮资标签）。 本国际标准没有定义确定任何特定读取速率的实际可行性所需的资格测试或采样要求。 [外文原描述]： ISO/IEC 18050:2006 specifies two methodologies for the measurement of specific print quality attributes of two-dimensional bar code symbols printed within the requirements of Digital Postage Marks. One of these methodologies is applicable to multi-row bar code symbologies and the other to two-dimensional matrix symbologies. ISO/IEC 18050:2006 defines methods for grading print quality attributes and deriving an overall assessment of symbol quality. In addition, it gives information on possible causes of deviation from optimum grades so as to assist users and postal operators in taking appropriate corrective action. ISO/IEC 18050:2006 applies only to those two-dimensional symbologies for which a reference decode algorithm has been defined, and provides an indicative read rate for limiting mean parameter values. The methodologies can be applied partially or wholly to other similar symbologies.
