Optical QR ScannabilityOPTIMAL
Standard Polarity
Standard dark modules on a light background with 4+ quiet zone modules establish optimal optical contrast for smartphone and industrial imagers. Real-world scanning reliability remains subject to print resolution, ink absorption, surface curvature, glare, and ambient lighting.
Optical Heuristic: Calculated module pitch is 0.61 mm/module at current physical dimensions.
Print recommendations are empirical optical guidelines. Always run a physical sample test print on your production substrate before final packaging runs.
Static QR Code Permanence: The target destination URL is permanently encoded directly into the physical matrix. Unlike dynamic redirect services, the destination cannot be changed post-print.
Zero Telemetry / Client-Side Privacy: Generated 100% locally in your browser memory without redirect proxies or third-party servers. To track scan visits in Google Analytics 4, Shopify, or Klaviyo, use the UTM tags generated above.
Pre-Print Static QR Confirmation
This static QR code cannot be modified once printed. Please verify your destination URL and test scan the screen code with your smartphone camera before sending files to prepress:
