Stock decides how a postcard feels in the hand; finish decides how it looks in the light and how long it survives. The three finishes you'll actually choose between for a postcard order are UV gloss, matte (or satin AQ), and silk lamination. They look identical on screen and feel different the moment you pick them up.
UV high gloss
A heavy clear coat cured under UV light. The surface is mirror-slick and bumps the perceived colour saturation about 10–15% — reds get redder, blacks get blacker. Wears its photography well.
Trade-offs: it shows fingerprints. It glares under direct office lighting. Pens slide off it. And the gloss is so even that the design is the entire visual — there's no paper character left to fall back on if the design is weak.
Pick UV when:
- The card is a single hero image (food, real estate, beauty).
- The colour itself is the selling proposition.
- The recipient will see it once.
Matte and satin AQ
Matte and satin aqueous coatings are water-based clear coats. They tone the gloss down without going fully flat — a satin AQ catches a faint sheen at angle, a true matte returns barely any. Either is a lot more forgiving than UV: less glare, fewer fingerprints, and the printed colour reads closer to the on-screen original (you lose the gloss-induced saturation boost, which sounds bad and usually isn't).
Pick matte/satin AQ when:
- The card is editorial — typography-heavy, layout-driven.
- The recipient might keep it.
- You want the design to feel premium without screaming for it.
Silk lamination
The big jump. Silk lamination is a thin plastic film bonded to the paper, not a clear coating brushed on top. The surface feels rubbery — there's a slight drag when you slide a thumb across it — and it's effectively water-resistant. The film blocks the paper fibres from absorbing ink, so blacks come out deeper than on AQ or UV.
Trade-offs: cost. Silk lamination roughly doubles the unit cost of a matte AQ card. And because it's a film, you can't write on it with anything but a paint marker.
Pick silk lamination when:
- The recipient is supposed to keep the card for weeks or months.
- The card will live in a wallet, glovebox, or kitchen drawer.
- You want depth in the dark areas of the design.
Two specialty finishes worth knowing
Spot UV applies a gloss patch only to specific areas of the design — a logo, a key phrase, a single element. It works on top of a matte base coat, where the contrast between matte field and gloss highlight is most dramatic. Spot UV doesn't make sense on a UV gloss base (the contrast disappears).
Matte lam + spot UV combines silk-matte lamination with a spot UV highlight. This is the standard finish for high-end real-estate cards and luxury hospitality — you get the durability of lamination and the visual punctuation of spot UV in one card.
The decision shortcut
- Mailing once, photo-heavy → UV.
- Editorial design, possibly kept → matte/satin AQ.
- Premium, will survive a wallet → silk lamination.
- Premium with a hero element → matte lam + spot UV.
