(57) In a printing apparatus, comprising a layer (3) which can be magnetized at least
in sections, a first magnetizing device (1) with a first north-south polarization
direction (4) for introducing a first magnetization direction (25) into the magnetizable
layer (3), and a second magnetization device (2) with a second north-south polarization
plane (17) for introducing a second magnetization direction (26) into the magnetizable
layer (3), with the first magnetization device (1) and the second magnetization device
(2) being provided for the predeterminable magnetization of a first position (22)
of the magnetizable layer (3), with a displacement of the first position (22) to an
effective region of the second magnetization device (2) being optionally provided,
it is proposed for improving the print quality, especially the achievable resolution,
that the first magnetization device (1) and the second magnetization device (2) are
arranged in such a way that a first magnetization direction (25) can be produced at
the first position (22) and/or a second magnetization direction (26) which is substantially
normal to the first magnetization direction (25).
