We've tested each one here specifically for illustration use — not for fountain pen writing, not for calligraphy, but for the moment when an illustrator floods a wash over an inked line and needs to know it will hold. Every ink in this section passed that test.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eNicker is our anchor. The poster colours have been used in Japanese animation production for decades — the white in particular has no real equivalent in Western materials. De Atramentis Document is the ink we recommend when people ask what to use with a dip pen for work that needs to archive. Rohrer \u0026amp; Klingner's Dokumentus is the only fountain pen ink independently certified waterproof to DIN ISO standards, which is a remarkable thing to be able to say about a bottled ink.\u003c\/p\u003e","products":[{"product_id":"nicker-poster-colour-white-animation-ink","title":"Nicker Poster Colour White — Animation Ink","description":"\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eWhy illustrators reach for Nicker White\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eMost white inks compromise. They dry translucent, bead on dark surfaces, or change consistency between bottles. Nicker White doesn't. The formulation was developed for professional animation production, where consistency across hundreds of hours of work is not optional. The result is an opaque white that covers cleanly in a single pass, holds its body on a loaded brush, and sits on top of finished ink lines without spreading.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eWhat makes it different\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe pigment load is higher than most Western poster colour whites. This means the coverage is genuine rather than approximate, and thinning with water produces a range of opacities that all behave predictably.
