Document inks with ISO 12757-2 certificate in 9 colours The development of our document inks for fountain pens took a total of 12 months. The focus was on selecting and testing the pigments to be used and their behaviour in the fountain pen, the flow properties during the writing process and the use of various additives to achieve the properties required for DIN ISO certification. The result is document-proof inks for fountain pens that differ significantly from inks already available on the market. Certification of the document inks The DIN ISO certification of our document inks was carried out by the independent Paper Technical Foundation (PTS). As part of the certification work, the document inks were tested for eraser resistance, ethanol resistance, hydrochloric acid resistance, ammonia resistance, bleach resistance, water resistance and light fastness. The tested fountain pen inks meet the requirements of the above-mentioned properties according to DIN ISO 12757-Part 2: 1999 (see PTS test report no. 45.240 dated 06.02.2023). In Germany, the inks thus meet the requirements of the Dienstordnung für Notare/Notarinnen (DONot) (Service Regulations for Notaries), the requirements of the state ministries of justice, the Bundeshaushaltsordnung (Federal Budgetary Regulations), the Dienstanweisung für das Standesamtwesen (Service Regulations for Civil Registry Offices) and the requirements of the Bundesärztekammer (Federal Medical Association). Application They are used in a similar way to standard fountain pen inks. They can be easily drawn from the 30 ml ink jars into a converter or filled into standard fountain pen cartridges using a syringe or needle bottle.Please take care not to let the fountain pen dry out. As the inks are waterproof and permanent, the resistance will also show in the dried-up fountain pen. It will then take a great deal of effort to clean the fountain pen. Now you just have to decide which colour you will use to sign your documents in future.
