    • The invention discloses a device and a process for producing indicia comprising magnetically oriented magnetic or magnetizable particles in an ink or coating composition on a sheet of substrate material. The device comprises a flat-bed screen-printing unit having a flat printing screen and a printing platen for receiving said sheet, the printing platen having an upper surface facing the printing screen and a first direction along its upper surface along which said sheet is unloadable, and a magnetic orienting unit comprising multiple magnet assemblies. The magnetic orienting unit is disposed below the upper surface of the printing platen, said multiple magnet assemblies are disposed along said first direction, and all of said magnet assemblies are concomitantly movable from a first position away from the upper surface of the printing platen to a second position close to the upper surface of the printing platen.The magnetic orienting unit comprising one or more magnet assemblies can also be used as a stand-alone flat-bed magnetization device, subsequent to the printing process, e.g. as an additional process station following a conventional flat-bed or rotary screen printing unit. Processes of producing printed documents using the disclosed devices are shown as well.
    • 本发明公开了一种用于制造标记的装置和方法,该标记包括在基片材料片上的油墨或涂层组合物中的磁性取向的磁性或可磁化颗粒。 该装置包括具有平面印刷丝网的平板丝网印刷单元和用于接收所述片材的印刷台板,所述印刷台板具有面向印刷丝网的上表面和沿其上表面的第一方向,所述片材不可在该第一方向上卸载 以及包括多个磁体组件的磁性定向单元。 磁性定向单元设置在印版的上表面的下方,所述多个磁体组件沿着所述第一方向设置,并且所有磁体组件可以从远离印刷版的上表面的第一位置同时移动到 第二位置靠近印版的上表面。 包括一个或多个磁体组件的磁性定向单元也可以在打印过程之后用作独立的平床磁化装置。 作为跟随常规平板或旋转丝网印刷单元的附加处理站。 还示出了使用所公开的设备制作打印文档的过程。
