specially formulated ChromaLife100+ ink. The ink produces professional
quality & long-lasting photo prints, ideal for displaying printed
works of art. Canon's proprietary FINE (Full Photolithographic Inkjet
Nozzle Engineering) technology provides sharpness and detail. The
individual ink system helps increase efficiency since you'll only be
replacing the color that runs out.
