Overview
ABSTRACT
Magnetography, or magnetic printing, involves transferring magnetic ink onto a medium by the attraction of a written magnetic medium. This technology is located in niche markets where its direct competitors cannot meet special requirements, such as security, with its magnetic ink, or printing on a variety of substrates, or printing on demand. This article details the different steps required to print, the functioning of the different elements of the printer as well as the future developments. Finally, the end of the article is devoted to the presentation of an example of a printer sold by the company NIPSON Technology.

INTRODUCTION
This article is dedicated to the magnetographic printing technique. Magnetography, or magnetic printing, involves transferring magnetic ink onto a substrate via the attraction of a written magnetic medium. This technique is used in niche markets where its direct competitors are unable to meet customer needs (security with its magnetic ink, printing on a variety of substrates and printing on demand).
Magnetography proceeds in three stages:
– the recording of a latent magnetic image on a magnetic medium, in the form of one or more magnetized domains (whose size depends on the targeted resolution) included in a large demagnetized domain;
– developing said image using a magnetic ink;
– and finally the transfer of the ink onto a support (paper, for example).
Finally, when you want to write new information, a fourth step in the magnetic printing process is necessary: erasing the written information.
In this article, we'll look at how the various printer components work together, as well as future developments. The article presents the example of a printer sold by NIPSON Technology.
