FOR IMMEDIATE RELEASE For more information, contact: AIM Global Tackles Direct Part Marking Verification Technical Symbology Committee Begins Work on Verification Procedures for Low and No-Contrast Direct marked 2D Matrix Symbols
In response to requests from the user community, the work will focus primarily on two-dimensional (2D) matrix symbols that are the most commonly used symbols for direct part marking in industries such as aerospace, automotive, and electronics. Direct part marking includes symbols that are laser etched, peened or molded into items. These symbols present very low or no-contrast conditions for readers. Since they often require specialized reading set-ups, current methods of verifying direct marked symbol print quality do not provide sufficient guidance to accurately predict real-world reading performance for these symbols. The committee will use the recently published ISO standard for 2D symbol verifier conformance (ISO/IEC 15426-2) and the ISO standard methodology for measuring the quality of 2D symbols (ISO/IEC 15415) as a basis for its work. While these standards offer an excellent starting point for this work, the lack of contrast in direct marked symbols between the matrix symbol elements and the item itself presents a special set of challenges. The committee will review existing parameters for symbol verification and issue recommendations for improvements to more closely predict reading performance of direct marked symbols under real-world conditions. The goals include recommendations to enable development of a verification specification for direct part marking and to define recommended lighting set-ups that would enable ISO/IEC 15415-type methods to be applied reliably in open systems.
