Bibliography

Describes: - 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; - methods for evaluating and grading these measurements and deriving an overall assessment of symbol quality; and - information on possible causes of deviation from optimum grades to assist users in taking appropriate corrective action.
