I’ve not done a lot of printing with these inks yet but first impressions are good. For everyday photo and document printing they are just fine. Anyone wanting very accurate colour renditioning will want to match ink profiles with a specific paper profile. Third-party inks such as these don’t come with printing profiles (there’s not even a manufacturer’s name on them) so the supplier might want to consider producing a such a profile. Also, there’s no way yet of knowing how good the ink’s longevity will be. That said, the price is very good offering a big saving over Canon’s own branded inks, and for most people these will be fine.
