Make every printed QR easy to scan.

Use dark ink on a light background and keep the blank quiet zone around the code. Avoid stretching, cropping or covering the corners.

Export SVG for scalable artwork or a print PDF. Every Laavia export is checked by a decoder at two sizes; this check does not replace a physical print test.

Print a sample at the intended size and material. Scan it with Android and iPhone cameras in the lighting and distance your audience will use. Dense payloads need a larger printed size.
