Printing seal labels on a thermal printer

UPDATED 24.10.2026 · 4 MIN

Each seal comes with a PDF stamp for documents and labels for sacks and cartons. Every one carries a QR code to the public check page, so scanning it shows the seal as it stands today.

Before you startStamps and labels never show a score, band or state, because a printed copy outlives them. Printing is paused while the seal is suspended, and unavailable if it is expired or revoked.

1
Open the seal
Go to Seals, open the seal, and choose the Stamps and labels tab.
2
Choose the format
Pick PDF stamp (for documents), Sack label, Carton label or Small label. The tab shows the size of each, and a preview.
3
Choose black ink
Under Ink, choose Black for thermal printers, and for documents that will be faxed or photocopied. Black is one colour on white. Navy is for colour printing.
4
Download the PDF
Choose Download labels PDF (or the PDF stamp). The preview on screen is only a preview; the PDF is the file to print.
5
Print it right
Print at 100% scale, on white or unbleached stock. Never reverse the stamp out of a dark background. Keep 2 mm clear around the QR code, and do not print the stamp smaller than 45 x 18 mm.
