キヤノン PFI-4100 グレー顔料インクタンク (80mL)

Switching to this gray ink tank for the PRO-1100 was a noticeable upgrade—the LUCIA PRO II pigment gives my monochrome prints a richness I wasn't getting before. The 80mL capacity means I'm not constantly swapping cartridges, which saves me time during long print runs.

I was skeptical about spending extra on a dedicated gray ink tank, but the subtle gradations in my monochrome prints are noticeably smoother now. The 80mL capacity means I won't have to swap it out for a good while.

My B&W prints finally have that true neutral depth I couldn't get before—the LUCIA PRO II formulation handles gradients without any green or purple cast. The 80mL tank lasted through a solid batch of portfolio prints without a single head clog or hiccup.
