2D barcodes for production managers

Streamline your production line and protect your supply chain with high-performing 2D barcodes.

Why production managers need to move to 2D barcodes

With the ability to hold large amounts of data in a compact space, 2D barcodes are a powerful tool for production teams. They enable variable data printing (like expiry dates and batch numbers), support traceability, and can be scanned throughout the supply chain, including by consumers using their smartphones.

2D barcodes are also built for real-world conditions, with error correction to ensure they remain readable even if scratched, marked or damaged.

 

How to transition to 2D barcodes

 

Step 1: Start with a pilot product, line or category

Before scaling 2D barcodes across your product range, start with a focused pilot. Trialling a single product or category gives you the chance to fine-tune printing, quality assurance and data capture workflows.

 

Step 2: Update in-line printing systems

Step 2: Update in-line printing systems

  • In some cases, a simple GTIN can be printed before packaging.
  • For use cases requiring variable data (like expiry dates, batch numbers or serial numbers) in-line printing will be required during packaging.
 

You may already be printing human-readable batch codes or use-by dates in-line. However, 2D barcodes often require updates to both hardware and software systems.

Speak to Reynolds to find the right printing and labelling solution for your line.

 

Step 3: Integrate barcode quality checks into your SOP

Make 2D barcode quality part of your standard operating procedures.

  • Data validation: Check that variable data (expiry date, batch/lot, etc.) is being encoded correctly and kept up to date.
  • Print quality: Regularly inspect printed symbols to catch issues early. Barcode inspections should be part of your QA process.
  • Printhead checks: Print a horizontal line 3mm above each barcode across the width of the label — this helps identify issues with the printhead as labels are being produced.
  • Ongoing maintenance: Clean printheads after every label change or on a scheduled basis to maintain consistent print quality. Talk to Reynolds about creating a maintenance plan tailored to your print environment.

2D barcode implementation checklist for production managers

  • Use high-speed digital printing technology – ask Reynolds for expert advice.
  • Choose non-glossy label stock. For refrigerated goods, matte stock is recommended.
  • Maintain high barcode contrast for easy scanning.
  • Print at the correct size:
    • Target 0.625 or 0.750 X-dimension
    • Use a 22x22 module square format for DataMatrix codes
    • Base your symbol size on your printer resolution (300 DPI or higher recommended)
  • Include the GTIN below the barcode for manual fallback at POS
  • Test your barcodes before release:
    • Submit samples for a GS1 Barcode Check to verify correct encoding of AI data
    • Mandatory for suppliers to Woolworths and others using 2D scanning
     

    Speak to GS1 Australia or Reynolds for support with barcode printing, validation and verification.

FAQs

Do I need to use 2D barcodes?

It depends on the type of product information you want to share on pack. If you don’t need to encode machine-readable data like batch or lot numbers, use-by dates, or serial numbers, then 1D barcodes may still be sufficient.

However, if you're looking to improve traceability, recall efficiency or consumer engagement, transitioning to 2D barcodes can add significant value.

How do I get started with 2D barcodes?

It’s best to engage with a trusted solution provider early. The team at Reynolds can help you identify the right coding, labelling and data capture solutions for your product, packaging and operational needs. Early planning helps ensure a smooth rollout, whether you’re trialling 2D barcodes or transitioning at scale.

What is the GS1 Barcode Verification program?

Barcode verification helps ensure your barcodes scan correctly and meet global GS1 standards. You can submit your label samples to GS1 New Zealand for testing.

They’ll check barcode size, print quality, colour, numbering, and overall compliance.

After assessment, you’ll receive a Barcode Verification Report with any recommended changes.

Verification is especially important if you're supplying large retailers. Some require proof that your 2D barcodes are correctly formatted with valid GS1 Application Identifiers.
