This genuine Canon PFI-120 magenta (and the other 4 colours in the range) contains a full 130ml of ink, making it pretty substantial, for a standard capacity unit. Those who print more frequently may want to take a look at the high capacity PFI-320 magenta alternative, but the Canon 2887C001 will be fine for many. With each original Canon PFI-120M being filled with the highest quality magenta ink the manufacturer produces, this cartridge can help you in producing prints that display your hard work beautifully. The ImagePROGRAF printers compatible with the 2887C001 are perfect for printing high quality artwork in a variety of sizes, but Canon fully guarantees this ink for your complete peace of mind.
