I've some MegaTank to test in the next days will try on one with an expired ink, maybe a god news (refilling with all 4 original Canon ones is over 120€ in France). What do you think about ?and these cartridges can be found in Europe beyond the expiration date pretty much discounted ; I never had problems with such expired cartridges.
Tried T5431 PB on the same 130gsm Inkjet cast coated paperThat's a pretty good deal indeed.
It's the L365 driver print to XP-2101 printer on Premium Photo Glossy Quality, I also check the Matte High.L=24 is not a very good black level at all, it's the ink in combination with the coating of the paper. Please add a detail to the images - which printer did you use for the particular prints ? And which driver settings did you use ?
I see quite strong traces of the pizza wheels at the paper out patch - that is a sign that the coating swells for a short period - is it a cast coated paper or a PE/RC paper ? I remember from own tests that cast coated papers don't deliver as good a deep black level as PE/RC papers did. I got down to L=1.1 on a RC paper with the Canon PFI-105 black.
It's the L365 driver print to XP-2101 printer on Premium Photo Glossy Quality, I also check the Matte High.
The paper still the 130gsm Inkjet cast coated paper.
I would try on my RC glossy paper later.
I also check the Stylus Pro 4000 glossy paper behavior, it seems like not only full PG black channel. Other 6 ink channelsView attachment 14237 also print something when it's black.
