Certificates of Authenticity

The genuine article

A certificate of authenticity is a promise made on paper, so the paper has to keep it. We letterpress and foil stamp certificates for watchmakers, jewelers, artists, and printmakers: heavy cards with a seal you can feel, made to travel with the work for as long as someone owns it.

Three gold foil letter Cs stamped and embossed into white cotton paper

What We Can Do

A certificate rarely travels alone. We print the whole set together, so the card, the label, and the note in the box all look like they came from the same hand.

LetterpressType and artwork pressed into heavy cotton paper. The impression is the first thing a hand notices, and the hardest thing for a desktop printer to imitate.
Foil StampingGold, silver, copper, or a matte pigment foil, stamped with a heated die. Bright enough to read as a seal from across a counter.
Embossed SealsA mark pressed with a brass die, with or without foil. The same die makes the same seal every time, run after run.
Lines to Fill by HandRoom for the title, the edition, the reference number, the date, and a signature, on a paper chosen to take a pen well.
Matching Labels & Backer CardsLabels for the box, backer cards for a ring or a pair of earrings, tags for a strap or a frame. Same paper, same ink, same mark.
Notes for the ShipmentPersonalized notes and thank-you cards to tuck in with the piece, so the certificate isn't the only thing in the box that sounds like you.
Letterpress donut printed in green and tan ink on white paper, with gold foil sprinkles

Small enough to count

The sprinkles on this donut are gold foil, set into two colors of letterpress ink. Fitting foil that tightly is the same work that puts a seal exactly where it belongs on a certificate, or a logo on a jewelry card barely an inch wide.

On something meant to prove a piece is real, that precision is the point. Sloppy registration looks like a copy.

Brass embossing die engraved with three letter Cs, locked onto the honeycomb base of a press

A seal made of brass

The seal on a certificate starts as a brass die, engraved in reverse and locked into the press. Under heat and pressure it moves the paper itself, leaving a mark you could find with your eyes closed.

We won't pretend paper is a bank note. But a deep impression and a foil seal on heavy cotton stock are hard to fake convincingly, and the people who buy fine watches, jewelry, and editioned prints know the difference when they hold it.

We print every piece in our letterpress studio in Alexandria, Louisiana, and ship nationwide. Tell us what you make and how it ships, and we'll help you plan the certificate and everything that travels with it.
