PowerGrid technology increases read rates where a part's geometry, poor lighting, occlusion, or print-registration errors make it difficult to capture an image of the entire code. PowerGrid technology can locate and read codes even when the finder pattern, clocking pattern, or quiet zone is significantly damaged or completely eliminated. of the finder pattern, clocking pattern, or quiet zone.
