Rohrer & Klingner Dokumentus Ink – Braun

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)


Braun is the best ink of the pack. Not only it has all archival ink properties, it also has stunning colors. That’s precisely the kind of brown I enjoy most.
