- Provide a paper towel before removing the cap cartridges (this prevents dropping a drop of ink anywhere especially for PGI-525)
- Text printing in recto / verso. Black ink seems heavier than the original and most tend to "cross" the paper (80 g / m² average quality). But this is very acceptable for personal use.
- Print a photo to compare the quality of the ink using exactly the same picture and the same paper (Canon Photo more glossy II). The result is quite surprising and comparison difficult. The colors are identical. A bit less brightness but with this ink that reveals a bit more detail. The opinion of an expert in photography would be very interesting.
It remains to be seen holding the ink in time (especially for photos), wear cartridges and the wear of the print head with non-Canon cartridges. But overall I am very satisfied and ready to renew this purchase.
