  • BARCODE GRADING Guide, Best-Practices & Technica l Considerations

  • VANTAGE SOLVES TOUGH INTEGRATION PROBLEMS

    raw materials end product

    • Professional service resources as extensions of client engineering, operations, and quality groups

    • Turnkey projects, from management through execution: including analysis, design, implementation, startup and validation

  • ROB MAGEE FRANK GUTHRIEJOHN CAPANTS, P.E.

    Mr. Magee has over 20 years of experience as a technical software professional. He brings a deep experience in supply-chain systems integration, software development, cloud based technologies, information systems security and distributed application design to the Vantage portfolio of clients.

    Mr. Capants is responsible for implementation activities for Vantage clients in the packaging, serialization and automation service. Previously, Mr. Capants was at Teva Pharmaceuticals, where he served as Executive Director of Engineering Technology and Qualification.

    Mr. Guthrie manages all aspects of select Vantage Consulting clientele, from initial development through project management and overseeing technical teams. Mr. Guthrie’s background includes extensive implementation of serialization and aggregation levels on multiple packaging lines.

  • • What is Barcode Grading?

    • How Barcodes Are Graded

    • When & Where to Grade

    • Substrate Considerations

    • Printer Considerations

  • • 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

    Decode Symbol Contrast Modulation

    Fixed Pattern Damage 5Grid & Axial Non-Uniformity

    Ex. Data Matrix Ideal Grid

  • • Pass / Fail • Subsequent grading relies on

    pass • Failure indicates an overall

    failure for the barcode • Common failure cause:

    Insufficient quiet zones

    D E C O D E

  • • 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

    PA R A M E T E R S

    S Y M B O L C O N T R A S T

  • • Graded 0 through 4 • Uniformity • Consistency of contrast • Common Failures:

    Reflective substrates, uneven printing, print head/paper shift

    M O D U L AT I O N

  • • 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

    F I X E D PAT T E R N D A M A G E

    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
