에프슨 Stylus Pro 7800 / 9800 마젠타 UltraChrome K3 잉크 카트리지 T603B

I've been using these K3 inks for a few months now, and the lightfastness is incredible — my test prints haven't faded at all under strong light. The cartridge itself clicked right in without any fuss, and the magenta tone is exactly what I need for my photo work.

The black density on matte paper is noticeably richer than with my previous ink set, and the gloss differential on glossy stock is practically gone.

My printer finally stopped banding on color blends after switching to this cartridge—the K3 pigment is noticeably more consistent than my old ink. I love that it builds on UltraChrome’s earlier stability.
