What are duplex and triplex business cards?
A standard business card is printed on a single sheet of card stock, usually between 260 and 400 gsm. Duplex and triplex cards take a different route. Instead of one heavy sheet, two or three thinner sheets are glued together into a single laminated block. A duplex card bonds two layers, a triplex card sandwiches three, and the middle layer is often a bright colour that shows as a stripe along the cut edge. The result is a card that reaches 600, 700 or even 800 gsm and still cuts with a clean, square edge.
People who search for thick business cards or 600gsm business cards often imagine a single milled sheet. However, most premium weights above 450 gsm are constructed by lamination rather than pressed as a single ply. Bonding thinner sheets keeps the card flat, allows the printer to apply a different surface on the front and back, and makes room for a colored core that a single sheet cannot provide.
Why do printers use multiple layers of stock instead of using a single thick sheet?
Paper mills produce uncoated, coated, and cotton stocks up to a certain point. Beyond roughly 400 gsm, a single sheet begins to crack when scored and feeds unevenly through a press. Gluing two 300 gsm sheets back to back produces a 600 gsm card that remains rigid and trims cleanly. A three-layer construction further increases the weight and incorporates the middle ply into the design. This is why searches for luxury business card printing and multi-ply business cards consistently lead back to duplex and triplex work.
- Duplex paper, which consists of two layers, typically ranges from 600 to 700 gsm. It is flat and stiff, with a plain or matching edge.
- Triplex, a card consisting of three layers, typically weighs between 700 and 900 gsm. It features a colored seam running around the card.
- A mixed-surface duplex, featuring one matte sheet and one textured sheet. This allows each face to print and feel uniquely.
Coloured cores and painted edges
The visible seam is the reason many buyers choose triplex. A neon pink, deep navy or bright yellow core turns a plain white card into something people turn over in their fingers. If you want colour on the rim of a duplex card instead, edge painting adds a coat of ink around the trimmed sides after the block is cut. Both effects read best on uncoated or cotton stock, where the fibre holds the colour and the surface stays soft to the touch. On a heavily coated sheet the painted edge can look thin, so the choice of stock and the choice of edge treatment go together.
How thick is considered thick, and how does the weight compare?
Weight on its own does not tell the whole story, because two cards at the same gsm can feel different depending on the fibre. Still, gsm is the number most people ask for, so it helps to see where duplex and triplex land next to a normal card. If you want the full background on single-sheet weights, our guide on card thickness explained across 260, 300, 350 and 400 gsm covers the everyday range, and this article picks up above it.
| Construction | Typical weight | Feel in the hand |
|---|---|---|
| Single sheet | 300 to 400 gsm | Firm, standard business card |
| Duplex | 600 to 700 gsm | Noticeably rigid, does not bend |
| Triplex | 700 to 900 gsm | Solid block with a visible edge stripe |
For most professional cards, a 600 gsm duplex strikes the perfect balance. It feels substantial but is not awkward to carry in a wallet. Additionally, it is more cost-effective than a triplex.
What to check in your artwork before placing an order.
Layered cards change a few things in file setup. Because the card is thicker, any border you place near the edge will look uneven if the trim shifts even slightly, so keep frames well inside the safe zone or drop them entirely. Solid dark backgrounds are fine, but remember the coloured core, not your ink, controls the edge colour. If you are choosing a core colour, ask for a printed sample rather than judging it on screen, since a screen green rarely matches a paper green. Our note on how to choose the right paper weight for business cards is worth reading alongside this if you are still deciding on stock, and the broader guide to business card materials and card stock covers surfaces and coatings.
Finishes that suit heavy layered cards
A thick card provides more space for finishing techniques to be effective. Letterpress and deep debossing can press into a heavier card without tearing through to the other side. Thus, duplex or triplex stocks are ideal for these effects. Foil applications sit well on the broader surface, and blind embossing retains its shape due to the card's ability to maintain its thickness over time. Soft-touch lamination on a 600 gsm duplex is a common request from design studios that want the card to feel warm and inviting rather than slick or cold. When combining a colored core with a foil logo and a painted edge, it is advisable to keep the front design simple so that the materials and their textures do most of the talking.
One practical aspect of durability is that thicker cards resist the softening of corners and bending of edges that can ruin a standard card kept in a pocket. This matters if the person to whom you hand the card keeps it on a desk for months. That is the whole point of spending more on the stock.
Ordering duplex and triplex business cards
At JustPrintCard, we print duplex and triplex cards to order. You can choose from various core colors, edge painting, and finishing options. You can either submit print-ready artwork or have us set it up for you. We also offer the option to choose the construction and weight. Before the full run, we produce a sample so you can feel the card before committing to a large quantity. Due to the hand-bonding process used to build these cards, lead times are a bit longer than those for a plain 350 gsm order. Therefore, it's important to plan ahead if you have a specific event date.
You can see the full range and start a quote on our business card printing pages, or browse related options across business and name cards. If you are unsure which weight or core colour fits your brand, send us your logo and a rough idea through the contact page and we will send back stock recommendations with a printed sample. A layered card is a small print job that people keep, which is exactly why it is worth getting the stock right the first time.
