FLYERALARM QR code specifications for best results

Colour mode

We recommend designing the QR code in 100 % black on a white background, or in negative white on a 100 % black background, to ensure optimum contrast.

Resolution

We prefer QR codes created as vector graphics. For image formats we recommend a minimum resolution of 300ppi.

Size

For QR codes we recommend a minimum size of 2 x 2 cm.

Material

When selecting the material please be aware that certain materials, in particular open ones such as mesh fabrics, may reduce the readability of the QR code.

Surfaces

Positioning QR codes on tapered or curved surfaces may severely reduce their readability.

Minimum line thickness

Please consult the general print specifications when selecting line thickness for QR codes.

Protective zone

We recommend creating a protective zone around the QR code, which is at least as wide as 4 QR code modules, in order to avoid problems with scanning.

Compatibility with scanners

The readability of the QR code may depend on the quality and specifications of the scanner used. For this reason we cannot guarantee readability on all scanners.

Changes after print

Changes to the QR code after print - such as varnish, damage or changes in shape, may affect their function.

Validity of information

We cannot take any responsibility for how current or correct the information linked via QR code is. Checking this information is the responsibility of the user.
