标准范围

ISO/IEC 18050:2006规定了两种方法，用于测量在数字邮资标记要求范围内打印的二维条形码符号的特定打印质量属性。其中一种方法适用于多行条形码符号，另一种适用于二维矩阵符号。ISO/IEC 18050:2006定义了打印质量属性分级和符号质量总体评估的方法。此外，它还提供了偏离最佳等级的可能原因的信息，以帮助用户和邮政运营商采取适当的纠正措施。ISO/IEC 18050:2006仅适用于已定义参考解码算法的二维符号，并提供了限制平均参数值的指示读取速率。这些方法可以部分或全部应用于其他类似的符号。

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.
