QR Codes: Test Before You Print

Check the destination, contrast, size, and scan behavior on the final artwork.

A QR code can look fine on a monitor and fail when printed small, placed on a curved surface, or viewed in poor light. Test the actual design before paying for a large print run.

Confirm the destination

Scan the exported design and inspect the full URL. Avoid temporary preview links and ensure redirects work before the code is printed.

Preserve contrast and margin

Keep a clear quiet zone around the pattern and use strong contrast. Avoid decorative elements that cover modules or reduce readability.

Print a physical proof

Test at the intended size and distance with more than one phone if possible. Add a readable short URL nearby when space allows and make sure the destination works on mobile.

Before relying on the result, test a small example, keep an original copy when a file or value is transformed, and check the output in the application where you plan to use it. Browse the tools directory for a utility that matches your task, and use the other practical guides for related checks.
