Magnetic Ink
a variety of magnetic information carrier used for recording textual and graphic materials on ordinary paper and for reading it out magnetically.
Magnetic ink is made in the form of a carbonyl iron suspension in heptane or mastic with microscopic magnetic particles. Dyes are often added to facilitate the visual inspection of a recording (visible magnetic ink). Magnetic ink is used chiefly for mechanizing document processing (sorting, identifying, accounting, coding). It is applied either manually or by printing equipment.
