Your craft demands the highest care, so make sure you use only a genuine Canon Grey 29 Ink Cartridge to refill your PIXMA PRO-1 inkjet printer. The secret to the PGI-29's performance is twofold: specially formulated LUCIA ink for stunning professional-quality prints with long-lasting vibrancy, plus Canon FINE (Full Photolithographic Inkjet Nozzle Engineering) print heads for incredible crispness and detail. Because it's a genuine Canon cartridge, it ensures reliability and quality when you need it most.
