How to print

  1. Print on thick paper (200–300 g/m²) at actual size / 100 %, double-sided, flip on long edge. Each back lands behind its front.
  2. No duplex printer? Print the fronts page, put the sheet back in face down, then print the backs page. Try one test sheet against a window first.
  3. Cut along the card edges: 3 × 3 cards of 63 × 88 mm per sheet, no gaps. A 3–4 mm corner punch gives rounded corners.
  4. Laminate in glossy pouches. Holographic film makes the rare cards shine; toner-reactive gold foil works for legendary frames.
  5. Check a QR code with your phone before cutting the whole batch.
