Canon PFI-300GY Grey Ink Cartridge

Product Overview

AI-generated summary

Honestly, the Canon PFI-300GY is one of those “does exactly what it says on the tin” consumables. If you’re running a compatible Canon large-format setup, a grey ink like this can be genuinely useful for consistent neutrals, professional monochrome output, and cleaner shadow gradients than forcing greys out of other colours. For £13.66 ex‑VAT, that’s not bad at all for something that can directly protect print quality—especially if you’re printing often enough that you’ll actually notice when the grey starts looking dull or banded.

I wouldn’t bother if you’re not sure it matches your exact printer/model—Canon’s cartridges are notoriously “match-or-don’t-fit,” and buying the wrong one is an expensive lesson. Also, if you’re doing mostly full-colour work and rarely need grey-heavy prints (CAD, signage mockups, monochrome posters), you might just be tying up budget when a different ink set or colour usage strategy makes more sense. Bottom line: buy it if you rely on accurate greys and you’ve confirmed compatibility; skip it if you’re guessing or your jobs don’t really benefit from dedicated grey ink.
