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.

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.

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.
