4.2 - Code Readability Index
The Readability Index provides a measurement of a specifi c symbol’s ease or diffi culty to be decoded
by the CR3. The Readability Index is specifi c to the CR3, and should not be confused with a
verifi cation 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-specifi c 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, refl ection, 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 fi xed mount positioning) which fi xes 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.
