Grading Data Matrix Symbols: Enhancing ISO-15415 with ISO 29158
Introducing ISO 29158 AIM-DPM
The ISO 29158 AIM-DPM method enhances the grading process outlined in ISO-15415. This method is designed specifically for evaluating Data Matrix symbols, a widely used two-dimensional (2D) barcode format.
Modifications to the ISO-15415 Process
ISO 29158 makes several key modifications to the ISO-15415 grading process:
- Updated Symbol Contrast Calculation: Calculates contrast differently to better assess Data Matrix symbols.
- DPM-Modified Defects: Introduces additional defects specific to Direct Part Mark (DPM) symbols, such as scratches and dents.
- Separate Grading Scales: Establishes distinct grading scales for DPM and non-DPM Data Matrix symbols.
Benefits of ISO 29158 AIM-DPM
Implementing the ISO 29158 AIM-DPM method provides numerous advantages: - Accurate Symbol Assessment: Provides more precise grading for Data Matrix symbols, ensuring reliable reading.
- Improved Symbol Quality: Identifies specific defects in DPM symbols, enabling manufacturers to enhance symbol quality.
- Increased Efficiency: Streamlines the grading process, reducing inspection time and costs.
Conclusion
The ISO 29158 AIM-DPM grading method is a significant advancement in the field of symbol verification. By modifying the ISO-15415 process, it ensures accurate and efficient grading of Data Matrix symbols, leading to improved scanning performance and reliable data capture.
