The Canon PGI-9 Grey Ink Tank cartridge is intended for reproducing photographic quality prints when used in a compatible Canon Pixma printer. The professional finish that can be achieved with the PGI-9 grey is possible because this cartridge uses Canon’s LUCIA pigment ink that is sharp, stable and very long lasting. This individual ink cartridge is available on its own or as part of a larger set. Just Ink and Paper is a supplier of genuine Canon ink cartridges and paper products to UK customers.
