There are several reasons why plastic engraved QR code plates are superior to printed QR code stickers:
Engraving is a more durable marking method than printing. Plastic engraved QR code plates are more weather and scratch resistant and can therefore last longer than printed QR code stickers . This means you won't have to replace the plates as often, which can add up to long-term savings.
Engraving provides higher image quality than printing. Lines and letters are sharper and more precise when engraved, making the QR code more readable and easier to scan . This can be particularly important when the QR code needs to be scanned from different distances or angles.
