Fewer characters means chunkier, more reliable modules. Watch the module size above: below 0.30 mm scanning gets unreliable. Certificates already printed keep verifying whichever mode you switch to later.

Output & alignment

Full mode draws the same content straight onto the template PDF you supplied, so you can print complete certificates without pre-printed stock.
Print the alignment sheet on one blank certificate, see how far it lands off, then nudge until the crosshairs sit on the rules. The offset is remembered on this device.

certificates.json is what the public lookup page searches. Upload it to data/certificates.json on your site, replacing the old one, each time you issue certificates — otherwise the new numbers will not be found.

Certificate template bundled

Currently using
Upload the empty certificate as a PDF and it is used for both the preview and the full-certificate output — vector, so it prints at full resolution however large you print. Stored in this browser. Re-upload here whenever the artwork changes.

Typeface substitute

Printing with
Futura is a licensed typeface, so it cannot be bundled here — and the copy embedded in your template PDF is a partial subset missing several digits and letters, so it cannot be reused either. The app is currently set in Jost, an open Futura-alike. Load your own Futura Book file below and it will be embedded in every certificate from then on.
Stored in this browser, so each machine is set up once. Look for Futura Book, FuturaBT Book or Futura LT Book in the fonts folder on the machine that made the artwork.

Before you print

The QR area on your blanks must be empty. The template has a placeholder QR at that spot — a per-certificate code cannot print legibly on top of it. Leave clear there when you reprint the stock, and this overlay drops straight in.
