How to Make QR Code Labels? 5-Step Practical Process + 6 Free Tools

Last week, a client working on a trendy food brand asked me: "I want to put a QR code on my product so consumers can scan it and view the ingredient list—how exactly do I do that?"

I asked him: "Static code or dynamic code?"

He said, "What's the difference?"

I realized: many clients want to create QR code labels but don't know the complete process + which tools to use. This article won't cover the theory—instead, it walks through a 5-step practical workflow and 6 free tools, so that you can do it yourself after reading.

5-Step Practical Process (Completed in 1-2 Days)

Step 1: Choose QR Code Type

3 types, choose based on your needs:

• Static Code: The pattern is fixed, and the content seen after scanning is fixed. Suitable for ingredient lists, instruction manuals, and warranty cards.
• Dynamic Code: The pattern is fixed, but the destination after scanning can be changed (modify the backend link). Suitable for marketing campaigns (one code per campaign) and variable data.
• Anti-Counterfeit Code: A unique code for each product + backend database + verification API. Suitable for anti-counterfeiting and traceability.

Beginner Suggestion: Start with static code for low trial-and-error cost (free), and upgrade to dynamic code once traffic picks up.

Step 2: Generate the QR Code

6 Free Tools (cost nothing):

• Cli.im (cli.im): The most commonly used domestic tool, supporting static + dynamic + batch generation
• WeChat Mini Program "QR Code Generator": Generate directly on mobile, no PC needed
• Canva: Rich design templates with a built-in QR code generator
• Inkscape: Open-source vector design, free and powerful
• Photoshop + QR Code Plugin: The top choice for professional designers
• LeXiang Barcode/QR Code: Single and batch generation

Recommendation: LeXiang Barcode/QR Code + Canva — LeXiang Barcode/QR Code for code generation, Canva for label design; these 2 tools cover 80% of needs.

Step 3: Design the Label

Lay out the QR code + product information (ingredient list / brand / net content) on the label.

Design Principles:

• QR code should occupy 30-40% of the label (don't make it too small, otherwise the scan rate will be low)
• Three-level hierarchy: main title + selling point + QR code
• Avoid placing the QR code in areas prone to wear (folds / edges)

Canva Templates: Search for "product label" or "QR code label"; apply a template and edit the text to finish one in 5 minutes.

Step 4: Printing and Proofing

5 Hard Printing Indicators:

• Minimum size ≥ 1cm × 1cm (scanning distance 10cm)
• Sufficient contrast (dark bar PCS value ≥ 75%)
• Quiet zone (left and right margins) ≥ 4 times the module width
• Avoid reflective materials (matte lamination OK, glossy lamination affects scanning)
• Print resolution ≥ 600 DPI (otherwise the code will be blurry)

Proofing Quantity: First print 100 sheets, use 5 mobile phones to scan and test 10 times — all 5 phones can scan it = pass.

Common Proofing Failures:

• Code too small (< 1cm) → cannot scan
• Insufficient contrast between background and code color (e.g., light gray background + dark gray code) → cannot scan
• Glossy lamination applied → reflective, cannot scan
• Low print resolution (< 600 DPI) → blurry code edges

Step 5: Mass Production Inspection

Must-Do Before Batch Printing:

• Printing factory delivers proof → self-inspect by scanning 10 times with each of 5 phones
• Sample 1-2% during batch production → ensure printing consistency
• Consumer scan data after shipment → use a dynamic code tool to check the scan rate

If scan rate is below 90%: check print resolution + quiet zone + lamination.
