How to Generate High-Resolution QR Codes for Print Advertising
Low-res images scan poorly on prints. We explain how to export sharp vector assets for advertising.
The Pain Point & Challenges
Exporting QR codes as low-resolution PNGs causes blur and pixelation when printed on large billboards or flyers, leading to scan failures.
The Dynamic QR Code Solution
Qodex supports exporting in vector formats (SVG, PDF). Vector files scale infinitely without losing quality, keeping edges clean.
Suggestions & Best Practices
- •Always export in SVG or PDF format when sending designs to professional printers.
- •Confirm the quiet zone margin (space around the code) is at least 4 modules wide.
- •Avoid glossy finishes on paper to reduce glare under bright sunlight.
Frequently Asked Questions
What size should QR codes be on standard A4 flyers?
Printed codes should be at least 1.2 x 1.2 inches (3 x 3 cm) to allow fast scanning.
Does print paper texture affect scanning?
Yes. Highly textured paper can distort module lines. Smooth or matte finishes are recommended.
