- In the cover editor, on the Back cover, add the seal's QR with the QR button.
- Place it where you like.
The work shows a sample; the real one appears in the sealed edition.
Its size
It's never smaller than 25 mm a side, so it can be scanned.
The credits page
What you export from an edition carries a credits page after the half-title, with the QR and the seal's date. In a working copy, without a seal, it's optional (Credits page, with the seal's QR code if the edition has one).
Without a seal
A working copy or an unsealed edition draws no QR (exaratio.com's seal).
