Bibliography

Specifies two methodologies for the measurement of specific attributes of two-dimensional bar code symbols, one of these being applicable to multi-row bar code symbologies and the other to two-dimensional matrix symbologies; defines methods for evaluating and grading these measurements and deriving an overall assessment of symbol quality and gives information on possible causes of deviation from optimum grades to assist users in taking appropriate corrective action.
