A process for the preparation of a printing original with a magnetic alignment and a printed matter with magnetic inks

摘要

A process for the preparation of a printing original with a magnetic alignment, characterized in that the method comprises:– Providing a magnet;– Heating of a partial area of the magnet having a heat radiation bundle,a new structure of a magnetic domain in the component region by the itself - magnetization of the magnet is formed, in order to the distribution of the magnetic field to change in the subregion;– Removal of the heat radiation beam, so that, after reduction to room temperature the new structure of the magnetic domain can be maintained, so that in the partial region of the changed distribution of the magnetic field is maintained in order the printing original with a magnetic alignment with a pattern to be designed with a predetermined magnetic orientation,wherein said heat radiation bundle an ultrasound heat radiation bundle is.
