Rohrer & Klingner Dokumentus Ink - Dunkelblau (Dark Blue)

[visvamitra]

Rohrer & Klingner is one of my favourite Ink makers. They offer nice and reasonably priced (especially in Europe) standard inks as well as two gall inks (Salix and Scabiosa). It seems the company is a little underrated among fountain pens aficionados. I believe their products should receive more attention.

 

 

Few months ago the company’s introduced a line of six Dokumentus Inks sold in 50 ml glass bottle. Dokumentus ink is the world's first fountain pen ink that conforms to the requirements of DIN ISO 12757-2 (the standard that determines archival quality). Rohrer and Klingner Dokumetus inks has been certified for use by registrars on official documents, they’re ph-neutral, permanent and archival.

 

Some criteria of this certification require color to remain readable after a defined dose of sunlight and under the influence of water the ink may only extend so far that the text line remain visible. ISO 12757-2 requires legibility and the ability to be stored for long periods of time. These inks should show resistance to water, light, ethanol, hydrochloric acid, ammonia, and bleach. I’ve tried only water. Test was positive. Water won’t do any harm to the text written with one of Dokumentus inks.

 

 

 

 

The line consists of six colors:

 

1. Braun (Brown)
2. Dunkel Blau (Dark Blue)
3. Grun (Green)
4. Hellblau (Light Blue)
5. Magenta
6. Schwarz (Black)

 

Dunkelblau is quite OK, not exciting but not bad either.

This looks like a nice blue-black, with some shading. Must seek this out.

 

Thanks for your review.

Thanks for the review. How about wetness / flow?

[visvamitra]

@alexander_k - it feels like most pigmented inks. The wrting feels smooth. The flow is good unless you leave the pen uncapped for minutes. Then it can have some starting issues.

Many thanks for the quick and clear response. Yet another ink to consider ...

Thanks for the review.

This one has possibilities. I like the shading, and that it doesn't lean teal. It would be interesting to see a side-by-side with the De Atramentis Document Dark Blue, of which I have a sample but haven't tried.

@visvamitra... How was the behavior if they were kept in pen for a longer duration... Like for week without use..

I'm definitely going to have to try this one. After Christmas...
