AIM Publishes Updated DotCode Symbology Specification
Pittsburgh, PA, August 02, 2019 --(PR.com)-- AIM, the trusted worldwide industry association for the automatic identification industry, providing unbiased information, educational resources and standards for nearly half a century, has announced the ratification and release of the revised International Symbology Specification – DotCode.
DotCode, introduced in 2009, is a unique, variable size, variable shape, matrix (2-D) symbology specifically designed for high-speed marking applications where alignment or connection of individual dots is problematic. Because DotCode decoding does not rely on finding continuous lines, DotCode offers a practical method to provide unique item identification at full production line speeds. The revised (version 4.0) DotCode specification defines expanded symbology-specific print quality assessment (verification) parameters based on a more granular (1/10 of a point) scale. Most importantly, the new specification defines a revised encoding algorithm to prevent rare but significantly flawed dot patterns that could have been produced under the original DotCode encoder.
George Wright, IV, a member of AIM’s Technical Symbology Committee and lead for the project, shared this comment on the relevance of the release, “This fundamental enhancement to DotCode defines a significant encoding improvement based on extensive new testing of the original encoder algorithm and real-world experience in printing and reading DotCode in anti-counterfeit and traceability implementations in the European tobacco industry over the past several years.” A podcast interview with Mr. Wright on DotCode is available online at https://www.aimglobal.org/podcasts.html.
The revised DotCode specification (Rev. 4.0) and associated encoding and mask scoring source code files are available for purchase from the AIM Store & Knowledge Resource Center (https://web.aimglobal.org/ecommerce).
