• Scanability - Consistent ability to read data under varying conditions• Verification - Examination and grading of optical
characteristics compared to industry standards
A matrix two-dimensional (2D) barcode which may be printed as a square or rectangular symbol made
up of individual dots or squares

• Pass / Fail• Subsequent grading relies on
pass• Failure indicates an overall
failure for the barcode• Common failure cause:
Insufficient quiet zones

• Graded 0 through 4• Contrast = Lightest Reflectance - Lowest Reflectance• Contrast between light & dark• Dark Print on Light Substrate = Better Grades• Common Failures:
Substrate is too dark/print is too light
Ex. Symbol with very poor Symbol Contrast G R A D I N G

• Graded 0 through 4• Uniformity • Consistency of contrast• Common Failures:
Reflective substrates, uneven printing, print head/paper shift

• Graded 0 through 4• Checks for damage to key barcode patterns used
for location & decode• Clock Track (dotted edges)• Finder Pattern (solid edges)• Quiet Zone
• Common Failures: Print head burnout/wear, spotty substrate

Ex. Symbol with Fixed Pattern Damage (clock track defect)
• Graded 0 through 4• Shape & vector deviation• Data Matrix should be
evenly distributed across square pattern

• Integrated to packaging line• Continuous Inspection
Off-Line / At-line• Remove samples from line
for sampling at intervals
• On-line/In-line• 100 % inspection/verification• Dynamic/variable conditions for
image capture• More difficult to calibrate

• Off-line/At-line• Calibration/traceability• Consistent, repeatable
conditions for image capture• Additional effort/activity to
collect and test samples
