信息技术 自动识别和数据采集技术 扩展矩形数据矩阵（DMRE）条码符号规范

[中文适用范围]： 本文件定义了称为扩展矩形Data Matrix（DMRE）的符号所要求的内容。它规定了DMRE代码符号特征、数据字符编码、符号格式、尺寸和印刷质量要求、错误纠正规则、解码算法以及用户可选的应用参数。适用于任何打印或标记技术生产的DMRE代码符号。原始Data Matrix代码大小未包含在本文件中，但由ISO/IEC 16022使用相同的矩阵布置、解码和错误纠正算法定义。 [外文原描述]： This document defines the requirements for the symbology known as extended rectangular data matrix (DMRE). It specifies the DMRE code symbology characteristics, data character encodation, symbol formats, dimensions and print quality requirements, error correction rules, decoding algorithm, and user-selectable application parameters. It applies to all DMRE code symbols produced by any printing or marking technology. Original data matrix code sizes are not covered by this document but defined in ISO/IEC 16022 using the same matrix placement, decoding and error correction algorithm.
