Through the Association for Automatic Identification and Mobility (AIM), industry now has standards to reliably verify
2D Data Matrix codes.

The purpose of code reading is to locate and decode a mark as quickly and reliably as possible in order to output the data. A good reader can handle variations in marking method, surface texture, etc., and can read at very low resolution.

Code verification is the process of inspecting and documenting whether a mark conforms to industry and internationally accepted standards. Once inspected, the verifier will output a grade of the code's quality. Verification systems require higher resolution of the code (5-10 pixels per cell) and all environmental variables, including lighting and part positioning, must be controlled to measure all mark attributes.

What metrics and methods can you use to assess the overall quality of a mark?

The goal of Mark Quality Verification is to ensure that the code is marked to the highest possible quality and to provide a reader the opportunity to achieve the highest read rate possible within a component lifecycle.
