I Was Wrong About The Blackest Fountain Pen Ink

The King is dead. In my last black fountain pen ink comparison, I declared Platinum Carbon Black the winner—but thousands of you told me I was wrong. You recommended I test darker, richer, and wetter inks, so today we find the true champion. We are pitting the reigning King against the most expensive challenger (Platinum Chou Kuro) and a surprisingly affordable underdog to find the scientifically blackest fountain pen ink on the market. Is the £50 Platinum Chou Kuro actually worth 4x the price of the competition?

Thank you for your support 🖤 I tested these on Clairefontaine and Midori MD paper to test shading, sheen, chroma, and pure blackness. Will the new champion be the most expensive, or can we save money with a cheaper alternative? 👇 Which ink is your daily driver?
