Incorporating a bar code quality procedure in the printing process is the best way to ensure thatbar codes are being printed correctly. A properly implemented verification procedure will increase overallbar code quality, reduce waste from misprinted bar codes, and achieve high first-time read rates. A highfirst-time read rate is an increasingly important factor in newer, more efficient systems where manuallyentered data is not acceptable as a backup function. Verification also minimizes the costs of returnedproducts due to poor reading or unaccountable bar codes.
