The CLI-42 Magenta Ink Cartridge from Canon is a 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.
