This extra high capacity compatible cartridge is filled with pigment based photo magenta ink, meaning this alternative to the Canon PFI-1700PM offers wonderful quality prints, even when compared to those produced by an original. Owning and operating inkjet printers like the Canon ImagePROGRAF PRO-4000s is far from cheap, but our compatible 0780C001AA certainly helps keep the ongoing costs down.Each compatible Canon PFI-1700PM ink cartridge we supply has the same 700ml capacity of a genuine extra high capacity photo magenta, but can be purchased for a much lower price. Our partners who have produced this compatible version of the extra high capacity 0780C001AA ink cartridge have made many changes to differentiate it from the design of the Canon photo magenta one, but your inkjet printer can still easily control the flow of pigment based ink from the cartridge.
