エプソン マットブラックインク Pro 7900 / 9900 / 7890 / 9890 (350ml) T5968

I was a bit skeptical about the price per cartridge, but the deep, even blacks this ink produces on my fine art paper are noticeably richer than my old set. The 350ml size has lasted through several large format prints without a hitch, so the cost per print actually feels reasonable now.

Installing the cartridge was a breeze and it clicked right into place without any leaks. The black ink distribution is incredibly even across my photo prints, especially on glossy paper where I used to get streaks.

I was a bit hesitant about the 350ml size, but it's actually perfect for my 9900 since I print constantly. The colors are incredibly rich and the black levels are deep, and I've noticed a real improvement in shadow detail compared to my old ink.
