When Canon designed the  superb Canon ImagePROGRAF Pro-1000 they knew they needed a quality red ink cartridge to accompany the 12 other colours they designated the machine, and the PFI-1000R was the result. The 80ml pigment based red Lucia Pro ink within the Canon 0554C001 works to great effect, creating photos with incredible permanence, that are of on unbeatable quality too!Designed to offer professional printers and enthusiastic amateur photographers an estimated 3,355 photos, the Canon PFI-1000R is great value too.PLEASE NOTE: Canon`s official estimated page yield for this ink cartridge is measured in 6x4 photos and NOT A4 pages.
