4.2 - Code Readability Index
The Readability Index provides a measurement of a specic symbol’s ease or difculty to be decoded
by the VS 2030. The Readability Index is specic to the VS 2030, and should not be confused with a
verication 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-specic 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, reection, 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 VS 2030
stand (or xed mount positioning) which 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.
