Below is a review of Diamine Indigo ink. I purchased this ink, as well as the Diamine Blue Black and Diamine Prussian Blue, as a possible replacement for my Lamy / Montblanc Blue Black. To my eye, all three inks provide an improvement over the rather dull Lamy / Montblanc ink. However, I ended up using the Diamine Blue Black as my "go to" ink. The Prussian Blue ended up being more of a grey with Medium or larger nibs (works fine with Fine), and the Indigo does not do well on slick paper like Diamine. I use it as a "signature" ink on the copier paper that I use at work, and it works quite well in that capacity. I also find that it works well on more porous papers like Rossi and Fabriano. I have included examples of all three inks with this review.



The inks appear color correct on my monitor, but the Rossi paper is more yellow / tan in real life than the scan shows. This ink does not bleed through any of the papers that I use regularly, including the most recent Moleskine papers.

Thank you for your great review.
I was planning to buy Diamine Indigo myself, but now I'm not so sure. The Blue-Back seems much more the colour I want, Indigo appears too light.
Maybe I'll try them both, now that there are smaller bottles .

I try hard to not roll my eyes at some of their naming choices ... and fail miserably.
