How to Use QR Studio Effectively
QR Studio is designed for practical QR workflows such as product labels, cafe menu links, event check-in pages, and guest Wi-Fi onboarding. You can generate a clean QR code, customize brand colors, and place a center logo while maintaining scan reliability.
For best results, keep strong contrast between foreground and background, avoid oversized logos, and test across iPhone/Android cameras before printing. If your QR is used on posters or packaging, generate at higher resolution and validate with different lighting conditions.
Release Checklist
- Verify contrast ratio and scan reliability on both iOS and Android cameras.
- Keep logo area moderate and avoid blocking finder patterns.
- Print one sample and test scan distance before mass production.
FAQ
What logo size is recommended?
Start from 15% to 22% of QR width. Larger logos may reduce scan success.
Can I use this for printed materials?
Yes. Export at high resolution and perform distance/lighting scan tests before final print.
