This extra high capacity compatible cartridge is filled with pigment based red ink, meaning this alternative to the Canon 0783C001AA offers wonderful quality prints, even when compared to those produced by an original. Owning and operating inkjet printers like the Canon ImagePROGRAF PRO-4000 is far from cheap, but our compatible PFI-1700R certainly helps keep the ongoing costs down.Each compatible Canon 0783C001AA ink cartridge we supply has the same 700ml capacity of a genuine extra high capacity red, but can be purchased for a much lower price. Our partners who have produced this compatible version of the extra high capacity PFI-1700R ink cartridge have made many changes to differentiate it from the design of the Canon red one, but your inkjet printer can still easily control the flow of pigment based ink from the cartridge.
