Ink, as a note in perfumery, is a synthetic or conceptual fragrance element designed to evoke the deep, slightly metallic, and musky aroma of ink or freshly printed paper. It is often used to add a unique, modern, and somewhat mysterious element to fragrances. Ink notes can be found in woody, aromatic, and leather compositions, bringing an unexpected twist that enhances the complexity and originality of a fragrance.

Ink has a deep, slightly metallic, and sometimes inky or paper-like aroma. Its scent can have a slightly bitter, smoky, or woody undertone, with subtle resinous or leathery nuances. The overall profile is fresh, slightly soapy, and often evokes a sense of something new and sophisticated, adding depth and a slightly industrial or intellectual character to perfumes. Ink notes can bring a modern, urban feel to fragrances, providing them with a unique, innovative edge.
