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.
