WATER RESISTANCE : I found that once dry, Diamine Indigo is reasonably water-resistant. A fair amount of the colour lifts but what is left behind is clearly legible.

DRYING TIME : Fairly brisk for a Diamine. About 15s on copy paper and a little longer on hard papers like Rhodia. This was from a well-cleaned pen with very high flow however.

BLEED THROUGH : I saw slight bleed-through on Pukka 80gsm copy paper but none on Rhodia.

LUBRICATION : Diamine Indigo feels smooth under the nib so I would say it is well lubricated for a Diamine. It gives a very sharp line. There were no starting issues in my Medium nib with wet flow.

Here is a close-up of the swab.

Diamine Indigo is a medium blue with very slight green tints. It therefore has a slight lean to a dark turquoise and is one of Diamine's older colours. It is not a densely saturated ink and cleans up well.

I did not see much shading in this pen. The ink does not smudge at all once dry.

Water tests were interesting...

The ink was fairly water-resistant and clung to the paper reasonably well. While a lot of the blue did lift and run, a good residual grey remained behind.

Great review, Daniel and I really like this colour. It's not inked up at present but I keep it in the rotation - most of the time!

Thanks for posting this review. Very informative. I just ordered the Diamine Indigo yesterday. Can't wait to try it out.

Good review. I like the color of this ink. It reminds me of Diamine Prussian Blue.

I got some of this ink a couple of years ago - mine looks gray with with a barely perceptible blue tinge, not at all like your scan. Wish it did look as nice as yours.
