FIRST THINGS FIRST
ALWAYS TEST on the final product with common QR readers, and keep in mind that:
1. Most QR readers can read QR codes with Dimensions of 8 x 8 mm, however, depending on the packaging dimensions we recommend QR codes between 1 cm x 1 cm and 2cm x 2cm for standard consumer packaging. Upwards there is no limit as you can see below.
2. Quiet zone - the area where the QR code ends and the other artwork begins. It is recommended to leave a quiet zone with a width equal to at least 4 QR Code cells:
3. Contrast is essential:
4. More apps work with dark-on-light vs. light-on-dark codes:
5. The contrast between the QR Code and the background must be sufficient for apps to be able to recognize it. Please, especially keep this in mind if you print the QR code on a clear label:
6. Printing on a smooth, flat surface is preferred; however, QR Codes can be displayed on all kinds of different surfaces, depending on the display type, the QR code may have to be bigger to ensure readability:
7. With regards to printed/engraved QR codes, if the material is more coarse (like cardboard), then the code may need to be bigger. The ink can bleed into the material and if the code is too small there will be nothing but a splotch:
8. Print on easy-to-reach-surfaces, surfaces that won't be distorted or covered once the product is packaged will prevent consumers from interacting with your code:
9. When printing on a curved surface, or applying a label to a curved surface (e.g. a bottle neck), you need to make sure that the curvature is not excessive and will not affect QR Code detection. As a rule of thumb, if the diameter of the cylinder is X, the size of the QR Code shall not exceed X/4. For example, if the diameter is 4cm, the QR Code shall not be larger than 1cm.
ALWAYS TEST on the final product with common QR readers
(yes, we have mentioned this before; it is important ;-) )
Please note:
- Include an APPEALING Call-to-Action.
- When designing your codes outside QR Manager, ensure a sufficient QR Version and sufficient error correction level is used
