The traditional botanical ink tone
Botanical illustration has used sepia-toned inks since the earliest scientific manuscripts — the warm brown reads clearly on white paper, photographs and reproduces well, and suggests the tones of dried specimens and pressed plants. Document Sepia continues this tradition in a modern, waterproof-once-dry formulation. For pen and ink botanical work intended for exhibition, publication, or long-term display, it is the correct ink.
Document Sepia vs standard sepia inks
Standard sepia inks — including Pilot Iroshizuku's brown offerings — are dye-based and not waterproof. Apply watercolour wash over them and the lines will run. Document Sepia is formulated to be waterproof once dry, making it suitable for pen and wash botanical work where watercolour is applied over finished linework. The warmth of the tone is consistent between bottles.

FREQUENTLY ASKED QUSTIONS (FAQ)
Is Document Sepia the same warmth as traditional Indian sepia ink?
It is a warm brown in the traditional sepia family — not the same formulation as historical cuttlefish-based sepia, but the colour is in the same tonal range. For exhibition-standard botanical illustration the visual result is indistinguishable from traditional sepia on white paper.
Will it hold up under watercolour wash?
Yes — once fully dry. Allow five to ten minutes on smooth papers before applying wash. Apply wash in deliberate single strokes rather than scrubbing back and forth over the dried ink lines.
Can I use this in a fountain pen?
Yes, with the same maintenance as Document Black — flush every one to two weeks. Not suitable for vintage pens.
