标准范围

复合符号系统是一类条形码符号系统，其主要区别特征是它们包括两个或更多个组件，每个组件是不同的符号，但包含一组相关数据。通常，一个组件是包含原始数据的线性符号，其可以在应用的某些区域中自行读取。另一个分量是包含限定主消息的补充数据的二维符号，并且要求读取所有分量以提取完整的消息。GS1复合符号系统就是这样一种符号系统。符号系统的使用旨在符合GS1通用规范。GS1复合符号由与相邻2D组件（编码补充数据，如批号或有效期）相关联的线性组件（编码项目的主要标识）组成。GS1复合符号总是包括线性分量，使得主要标识可通过所有扫描技术读取，并且使得2D成像器可以使用线性分量作为相邻2D分量的取景器图案。GS1复合符号始终包括一个多行2D组件，以便与线性和2D成像仪以及线性和光栅激光扫描仪兼容。GS1复合符号旨在根据GS1通用规范对识别号和识别补充数据进行编码。GS1对编号系统的管理确保分配给特定项目的识别码在全球范围内是唯一的，并且它们和相关的补充数据以一致的方式定义。ISO/IEC 24723:2010定义了GS1复合符号的要求。它规定了GS1复合符号特性、数据字符编码、符号格式、尺寸和打印质量要求、纠错规则和参考解码算法。对于GS1复合符号的线性和2D组件，除ISO/IEC 24723:2010中特别说明的情况外，适用这些已发布的规范。

Composite symbologies are a class of bar code symbology, the principal distinguishing feature of which is that they comprise two, or more, components, each of which is a distinct symbol, but which contain a set of related data. Typically one component is a linear symbol containing primary data, which can be read on its own in some areas of the application. The other component(s) is a two-dimensional symbol containing supplementary data which qualifies the primary message, and requiring all components to be read to extract the complete message. The GS1 Composite symbology is one such symbology. The use of the symbology is intended to comply with the GS1 General Specifications.

A GS1 Composite symbol consists of a linear component (encoding the item's primary identification) associated with an adjacent 2D component (encoding supplementary data, such as a batch number or expiration date). The GS1 Composite symbol always includes a linear component so that the primary identification is readable by all scanning technologies, and so that 2D imagers can use the linear component as a finder pattern for the adjacent 2D component. The GS1 Composite symbol always includes a multi-row 2D component, for compatibility with linear and 2D imagers, and with linear and rastering laser scanners.

GS1 Composite symbols are intended for encoding identification numbers and data supplementary to the identification in accordance with the GS1 General Specifications. The administration of the numbering system by GS1 ensures that identification codes assigned to particular items are unique world-wide and that they and the associated supplementary data are defined in a consistent way.

ISO/IEC 24723:2010 defines the requirements for the GS1 Composite symbology. It specifies the GS1 Composite symbology characteristics, data character encodation, symbol formats, dimensions and print quality requirements, error correction rules, and reference decoding algorithms. For those linear and 2D components of GS1 Composite symbols with published symbology specifications, those published specifications apply, except as specifically noted in ISO/IEC 24723:2010.
