Kakimori Sumi Black occupies a rare third position — a fine-ground pigment ink formulated to pass through fountain pen feeds without clogging, while remaining fully waterproof once dry. For illustrators who work in fountain pen line then add watercolour or ink wash, this is the correct tool.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003cstrong\u003eSumi Black vs De Atramentis Document Black\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003eBoth are waterproof blacks for illustration use but they serve different contexts. De Atramentis Document Black is a waterproof dye-based ink — excellent for dip pens and available at lower cost. Kakimori Sumi Black is a true pigment ink — denser, more archival, and fountain pen safe. Use Document Black for dip pen work and budget-conscious illustration. Use Kakimori Sumi Black when the work will be in a fountain pen, requires maximum archival quality, or will be reproduced professionally.\u003cbr\u003e\u003c\/p\u003e","brand":"Kakimori","offers":[{"title":"Default Title","offer_id":53230208057672,"sku":null,"price":0.0,"currency_code":"GBP","in_stock":false}],"url":"https:\/\/inkwellartsupplies.com\/products\/kakimori-sumi-black-waterproof-illustration-ink","provider":"Inkwell Art Supplies","version":"1.0","type":"link"}
