Analysis of magnetic printing

Magnetic printing is mostly used in cheques for securities to avoid being counterfeited. Magnetic printing is called MICR, which is also known as Magnetic lnk. Short for Character Recognition. Its main printing purpose is from 0-9 and other numbers and symbols, and such numbers or symbols are printed in magnet powder mixed ink below the check. Since the electrical wave differences produced by the text are different, it is only the identification on the classification process. Magnetic printing is widely used in cheques. For example, in the United States, there are 20 billion cheques in one year. In terms of working methods, it is divided into manual and mechanical.

The paper used for magnetic printing is itself magnetically mixed with iron powder. In printing, since the difference in the electric charge of the ink attached to each numeral and symbol is different, the magnetic attraction of the paper and the magnetic force of the paper at the time of printing constitute different radio wave differences for the purpose. In the future, magnetic printing will be used not only for cheques, but also for other securities.
