Yes, QR codes can be printed on curved surfaces—but they may not always scan reliably.
Modern smartphones often struggle to detect QR codes if the surface is too curved or the print quality is poor. To increase scannability:
Use high print quality to maintain the clarity of the QR code pattern.
Avoid overly reflective materials like glossy glass or metal in curved forms, as they can distort the code.
Ensure the QR code is not too small or too large—the recommended print size is at least 2x2 cm (0.8x0.8 inches). Anything smaller can be unreadable, especially on curved surfaces.
Test the code before using it publicly to ensure it scans correctly from multiple angles.
🧾 Tips for Printing on Curved Materials
QR codes can be printed on materials like paper, plastic, vinyl, glass, metal, wood, and even fabric. However, curved surfaces like bottles or tubes require extra care:
Keep the code placement in the flattest area possible.
Use printable formats like SVG or EPS for better resolution on curved or flexible materials.
Opt for durable materials like vinyl or plastic if the item is exposed to wear or outdoor use.
While it's possible to scan a QR code on a curved surface, proper sizing, positioning, and material choice significantly improve success rates.
