This genuine Canon PFI-120 yellow (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 yellow alternative, but the Canon 2888C001 will be fine for many. With each original Canon PFI-120Y being filled with the highest quality yellow ink the manufacturer produces, this cartridge can help you in producing prints that display your hard work beautifully. The ImagePROGRAF printers compatible with the 2888C001 are perfect for printing high quality artwork in a variety of sizes, but Canon fully guarantees this ink for your complete peace of mind.
