9 cards per A4 page at trading-card size (63 × 88 mm), edge to edge with crop marks — cut along the marks. Printed in ink-saver style: white paper, thin coloured lines, no solid fills. In the print dialog choose Save as PDF (or your printer), scale 100% / Actual size, margins None, and Background graphics on. With card backs: print double-sided, flip on long edge, and use card stock or thick paper so cards can't be read through.
