4.2 - Code Readability Index
The Readability Index provides a measurement of a specific symbol’s ease or difficulty to be decoded
by the CR3. The Readability Index is specific to the CR3, and should not be confused with a
verification quality measurement.
The Readability Index is a blend of information obtained from the internal operations of the decoding
algorithm pertaining to contrast, symbology construct, error detection, forward error correction (if
applicable), and other symbology-specific characteristics.
The Readability Index is a score on a scale of 01 (very poor) to 100 (very readable). Due to differences
based on motion, skew, reflection, focus, and ambient lighting, the Readability Index on the same
symbol may vary somewhat from read to read. However, a poor contrast or damaged symbol will
score lower than a high contrast undamaged symbol. The Readability Index can be used as a quick
check on the reliability of label generation or marking systems. When used in conjunction with the CR3
stand (or fixed mount positioning) which fixes the distance from the reader to the symbol, and constant
ambient light, the Readability Index provides a symbol quality assurance tool and check point for
feedback to an overall label or marking quality control system.
