The color has two sides. When writing with it it is a nice light blue-black color. After a few seconds it turns to a very dark blue-black. A swab does not the nice dark color after drying. It is really a dark blue-black.
The ink writes just great and is very smooth. The flow is good in a wet writing Pelikan M1000 (fine) but also in a Lamy Safari (medium). I noted it becomes blacker on some papers then in a Moleskine. On papers with a smooth surface it can have some start problems, but never in a Moleskine. After starting on a smooth surfaced paper it writes just as good.
I wrote this written review with my Conway Stewart Nelson II (fine) Can't read it? Here's the translation:
"Diamine Registrars Ink
I filled my Conway Stewart (fine) with Diamine Registrars Ink.
It is an ink made in the UK and comes in bottles of 30ml. Diamine states that this ink is legible for hundreds of years. This ink is based on an iron-gall formulation.
While writing it turns from blue to 'black' when dry. It flows great. This ink has no shading. On this Moleskine paper their is no feathering or bleed through at all. Iron-gall ink takes a bit longer to dry. On this paper it takes about 18 seconds to dry. $ 0,32/ml.
The color when dry is a nice very dark blue.
The bottle with only 30ml. is rather small for pens with big nibs. There's also a bottle with 100ml.
Here's a desktop you may use freely. It is at 1920 x 1200. Click on this link.
Well there it is another great ink that is 100% Moleskine-proof. I could not find a Moleskine in my collection where it had bleed through or feathering in any pen.
