ABSTRACT:
The invention relates to a printing method and to a magnetic printing machine, which makes it possible to obtain images in at least two colors on a printing medium. A magnetic recording device (13) is arranged such that when it is excited by pulses it forms magnetized points on the drum (10). The points comprising elementary magnetic domains having magnetizations in different directions. The machine further includes developer applicators (40, 42), retouching devices (41, 43) and a transfer post (45), where the developers deposited onto the drum (10) are transferred onto a strip of paper (20).
