Understanding Long-Edge Duplex Mirroring
Duplex printing flashcards requires exact mathematical alignment so the reference on the front directly matches the verse on the back:
- Automatic Column Inversion: When a sheet of paper is flipped horizontally (flip on long edge), Column 1 on the front becomes Column 2 on the reverse. Our engine automatically mirrors the card placement so backs and fronts pair cleanly without manual rearranging.
- Zero Perimeter Waste: The cards are geometrically mapped to the full 8.5" × 11" sheet dimensions. You only make cuts along the interior dotted lines without having to trim excess perimeter margins.
- Uniform Safe Margins: Every card contains built-in internal padding so your desktop printer never cuts into Scripture text near paper borders.
