Print a QR code at a practical physical size
Print Studio keeps the QR as a real physical object rather than a vague image on a screen. Choose a preset format or custom dimensions, keep the artwork at actual size, and test the finished piece before a large print run.
If you are unsure how small the QR can safely be, use the minimum-size calculator first. Then test the exported artwork with QR Code Checker before printing important material in quantity.
