AIM PUBLISHES NEW STANDARD FOR READABLE BAR CODES
AIM Inc., a Pittsburgh-based, non-profit authority on automatic identification and data collection, has published an International Symbology Specification for PosiCode.
The new position-based standard has been designed for creating readable bar codes where controlling bar widths may be difficult, especially in direct-marketing processes such as laser engraving, chemical etching, dot peen or indent marking and machining.
A position-based symbology decouples the widths of the bars from their positions. The centers of the bars are laid out on a grid of equally spaced parallel lines. Upon “reading” the code, the data is decoded based on the position of the bars rather than their widths.
PosiCode is capable of encoding numbers, letters and two punctuation marks. Additional information is available on the Internet at http://www.aimglobal.org/standards/symbinfo/posicode_overview.htm.
