Duplexed / two-ply stock
Two paper sheets bonded into one extra-thick stock, often mixing face colors or textures and turning the cut edge into part of the design.

What it is
Duplexed or two-ply stock is made by bonding two separate sheets face to face, then trimming them as one. It produces a card thicker than either sheet alone and can put a different color, texture, or finish on each face. A colored sheet also makes the cut edge read as color.
Reach for it when a business card, invitation, cover, or tag needs real weight rather than the illusion of weight from a coating. Two plies can make a two-tone object; a distinct colored stripe sandwiched between two face sheets is technically triplex, or three-ply, construction. MOO's Luxe cards are the familiar retail version of that colored seam.
Gotcha: this has nothing to do with duplex printing. The adhesive and grain direction matter: mismatched sheets can curl, and poor bonding can separate at a scored fold or exposed edge. Confirm the finished caliper, bond a dummy with the real stocks, and trim after bonding so the edges land flush.

Write a two-ply business-card production spec using a PVA adhesive duplexing process. Name the exact face stock and back stock, align both grain directions, calculate finished caliper from the two sheets plus the bond line, and specify bonding before final trim. Include a cured physical dummy, edge and corner adhesion checks, a curl check, and a separate triplex option if the design needs a distinct colored center stripe.
