Epson Stylus Pro 7800/9800 淺洋紅色墨水 (220ml) T603C

The K3 pigment formulation gives my prints a noticeably richer depth in shadows compared to standard inks. It flows consistently through the 7800 without any clogging issues so far.

I was worried about finding genuine 220ml cartridges for my 7800, but these work perfectly and the packaging was secure. The ink flow is consistent and the prints look vibrant without any banding.

The color gamut on these K3 pigment inks is stunningly rich, and this light magenta matches the rest of the set perfectly for seamless gradients. My test prints show zero banding and the 220ml cartridge lasts a good while on my 7800.
