Basic meaning of magnetic printing

Magnetic ink printing, referred to as magnetic printing, is an anti-counterfeit printing technology for special inks. The method of adding magnetic materials to ink is used for printing.

The base of magnetic prints requires moderate toughness, uniform thickness, smooth surface, no stretching or curling when the temperature and humidity changes, good water and corrosion resistance, good printing and processing adaptability, and low price. Commonly used materials include offset paper, coated paper, resin-impregnated paper, polyvinyl chloride (PVC), polyethylene terephthalate (PET), and other plastic film bases and composite materials, with a thickness of 150-800 μm. The requirements for magnetic powders are high magnetic saturation, uniform particle size, good dispersion, stability, and long aging. Commonly used magnetic hematite, iron oxide attached to iron. Magnetic ink is composed of magnetic powder pigments, binders, desiccants, antioxidants, wetting agents and other additives.

Magnetic print is a unique media produced by the combination of recording technology and printing technology. Its characteristic is that data can be written and read on magnetic cards, and words, patterns and photos can be visually seen.
