Engineered Nano-Pigment Performance
The De Atramentis Document range solves the classic dilemma of waterproof line-art: choosing between the convenience of a fountain pen and the absolute permanence of art ink. Unlike raw carbon fluids, this range utilizes sub-micron, nano-ground pigment particles suspended in a highly lubricated carrier fluid. The particles are small enough to pass through modern fountain pen feeds without clogging, yet they form an unbreakable, lightfast, and waterproof structural bond with cellulose paper fibers within minutes of hitting the page. It is the definitive layout choice for pen-and-wash illustrators, botanical sketchers, and legal document signatories.
Honest Note:
Who is it For?
FREQUENTLY ASKED QUSTIONS (FAQ)
Which Document colour should I start with?
Document Black is the primary recommendation — the most versatile and most used colour in the range. Document Sepia is the traditional choice for botanical illustration. Both have standalone product pages with more detailed guidance.
Is Document ink safe in a fountain pen?
Yes, with regular maintenance. Flush every one to two weeks to prevent the waterproofing agent building in the feed. Not suitable for vintage pens with rubber sac filling systems.
What is the difference between Document Black and standard black inks?
Standard black inks are not waterproof — they will run if wet. Document Black is waterproof once dry, making it suitable for pen and wash illustration and photocopy-ready zine work.
