Our duplex postcards reach up to 32pt by bonding two premium cardstock layers together. At 32pt, they are more than double the thickness of a standard 14pt postcard and comparable to the weight of a premium business card or a credit card.

A duplex postcard is made by adhering two separate sheets of cardstock together using a high-quality bonding process. The two outer faces can be printed full color, and if a colored middle layer is used, it shows as a visible seam along all four edges of the card.

The seam is a thin line of color visible along all four edges when you look at the card from the side. It is created by the middle layer of paper, which is a different color from the outer faces. Common choices include black, navy, red, and other rich accent colors that complement the postcard design.

Yes. Duplex postcards involve additional materials and a more complex production process compared to single-layer standard postcards, which is reflected in the price. The cost difference is meaningful for large campaigns, but for smaller runs, the premium impact is typically worth it.
