    • A method for producing an optical element, preferably a security feature, wherein a film having a first embossed hologram in an embossing layer is provided, and a second embossed hologram is embossed into the same embossing layer such that the first embossed hologram is partly replaced with the second embossed hologram. The invention further relates to a method for producing an optical element wherein an embossable film provided with an embossed hologram is partly filled with printing lacquer, and a method for producing an optical element wherein hologram embossing is prevented by prior partial printing of the embossing film with curable printing lacquer. The invention relates further to optical features producible by the inventive methods, documents of value having an inventive optical feature and a numbering embosser for use in an inventive production method.

    • A production method is provided by which a copied volume hologram from a multi-layer master is later customized by utilization of the color tuning properties of the light-curable materials used for the application onto personal documents. These holographic individual data, such as a passport photo, are also separately detectable, without the holographic elements copied from the master, that are visible under other viewing angles, impairing the visibility of the individual data. The volume hologram overlay obtained by this method is applied on personal and valuable documents to increase protection against forgery, possesses superimposed optically variable items of information that are separately visible under different viewing angles and give a defined color change under different view angles, wherein at least one of these items of optical information represents individual personal data, in particular a passport photograph.
    • 提供了一种制造方法,通过该方法,通过利用用于个人文档的应用中的可光固化材料的颜色调整特性来定制来自多层母版的复制的体积全息图。 这些全息个人数据,例如护照照片,也可单独检测,而没有从主体复制的全息元件在其他视角下可见,从而削弱了各个数据的可视性。 通过该方法获得的体积全息图覆盖层被应用于个人和有价值的文件以增加防伪的保护,具有在不同视角下分开可见的叠加的光学可变的信息项,并且在不同的视角下给出明确的颜色变化,其中至少 这些光学信息之一表示个人个人数据,特别是护照照片。
