DESIGN The GS1 US is also the code manager for the United Nations Standard Products & Services Code (UNSPSC). The UNSPSC provides an open, global, multi-sector standard for classification of products and services. Identify applicable commodity codes on UNSPSC website (www.unspsc.org). You can also contact GS1 US at their website (www.gs1us.org). 3.3.1 Bar Code Specifications Bar code print specifications are produced by combining three types of related specifications: 1. Application Standards are published by accredited standards organizations. Bar codes are used in many different applications with different scanning conditions. For example, one application involves packaging for retail check out lanes while another application is for coding shipments for conveyor lane routing in distribution centers. The specifications for bar codes used in these two applications are different because the conditions for scanning the bar codes are different. Accredited standards organizations provide specifications in the form of guidelines and stanards to assist in: Selecting the bar code type to be used, Structuring the data inside the bar code, Defining the printed human-readable information that is inside the bar code, Selecting bar code size within the acceptable range, Understanding where the bar code should be placed on the product, and Defining the minimum print quality requirements. 2. FIRST Print Specifications prescribe a minimal level of capability for all compliant printers. These specifications fall within the acceptable limits of the appropriate Application Standard for the bar code being printed and will assist in: Determining the minimum size for a bar code depending on the printing press and substrate, and Identifying the preferred bar code orientation given the direction the web or sheet will travel. 3. Job Specifications should be published for film or plate output. These specifications should assist in: Identifying optimum film/plate output resolution, and Determining bar width reduction (BWR) required by the specified print conditions. 3.3.2 Designer Responsibilities The designer, prepress provider and printer all bear responsibility for producing quality bar code symbols. Designers play a critical role in assuring a bar code conforms to all applicable Application Standards and FIRST Print Specifications. When creating an FPO (for position only) symbol, the designer must determine and communicate the symbol type and size, the color(s) used to print it, as well as the location and orientation on the printed product. Design Section 3.3 highlights the necessary information for creating an FPO symbol for flexographic packaging applications. Because designers are often involved in the substrate and color selection process, as well as the bar code placement, orientation and size determination, they should be aware of the design parameters for bar code performance. The designer should consider if the current design specifications might create scanning problems. Common design revisions requested because of the selected substrate or color include a larger symbol, a different symbol orientation, an extra layer of background ink, or a dedicated bar code print station. Please consult your product manufacturer, printer/separator for direction.
