Abstract

Настоящее изобретение относится к области способов и печатающих устройств для получения слоев с оптическим эффектом (OEL), содержащих магнитно ориентированные пластинчатые магнитные или намагничиваемые частицы пигмента на подложке. В частности, настоящее изобретение относится к способам, в которых используют печатающие устройства, содержащие первое устройство, генерирующее магнитное поле, установленное на устройстве для переноса (TD), и статическое второе устройство, генерирующее магнитное поле, для получения указанных OEL в качестве средств против подделки на защищаемых документах или защищаемых изделиях, а также в декоративных целях.The present invention relates to the field of methods and printers for producing optical effect layers (OELs) containing magnetically oriented lamellar magnetic or magnetizable pigment particles on a substrate. In particular, the present invention relates to methods that use printing devices comprising a first magnetic field generating device mounted on a transfer device (TD) and a static second magnetic field generating device to obtain said OELs as anti-counterfeiting agents. on protected documents or protected products, as well as for decorative purposes.
