Canon PFI-300 Red Ink Tank

The only thing I would add to the below is to store the cartridge package with the nozzles up.

The inks in the Canon PFI-300 Ten Color Ink Tank Pack are all pigment based archival inks. The prints can last between 100 and 300 years depending on the type of paper and storage conditions.

The Canon PFI-300 Ten Color Ink Tank Pack is pigment based ink and when used with weather resistant media will offer some weather of weather resistance.

Ink would have an expiration date listed on the pack. Ink should last 2 years in a cool dark place

Yes, it does.

When you use the Canon imagePROGRAF PRO-300 printer for the first time after you install the bundled ink tanks, the printer consumes a small amount of ink in the amount to enable printing by filling the nozzles of the Print Head with ink. For this reason, the number of sheets that can be printed with the first ink tanks is fewer than the succeeding ink tanks, which would not subsequently require filling the print heads. The printing costs described in the brochures or websites are based on the consumption data from not the first ink tank /ink cartridge but the succeeding ink tank /ink cartridge. Ink is sometimes used to maintain the optimal printing quality as well.

The ink would be Pigment based for both the colored inks and as well as the black inks.

My first tank to run out - new printer_ first set of ink tanks - was Photo Black. Rough estimate Grey and CO have 25% remaining, other colors more. Mostly printing close up photos of flowers, night photos, bird and animal photos, all with dark backgrounds in Highest Quality using Canon printer software. I got 39 - 8 1/2 x 11 inch PRO LUSTER prints the majority of them borderless.
