Magnetic printing ink

What is Magnetic printing ink?

Magnetic printing ink is made from magnetizable pigment, such as iron oxide black (Fe3O4)and iron oxide brown (Fe2O3), most of which are needle-shaped crystals below 1 μm. After being processed with magnetic field, they can easily arrange themselves with magnetism and get relatively high residual magnetism. Consequently, the ink made from them has magnetism and therefore becomes magnetizable ink. It is widely used in areas such as the classification, retrieval and identification of bank tickets and those in postal services. It can be made into magnetic letterpress printing ink, magnetic colloidal ink and so on.

Patterns and logos printed with magnetic ink containing magnetic substance can be checked by magnetic detector, and printed passwords can be read out by information decoder and recognized through rubbing effect of automatic processing device.
