摘要： The invention comprises a method for producing identification marks (5) on layer-structured paper or board (7) to be manufactured in a continuous web and the marked papers and boards obtained with this method. With this method, the marks (5) are made with a laser beam on a moving web form fiber layer (1), on which a second layer of material (6) is subsequently overlaid in such a way that the marks remain inside the layer-structure of the moving web. The second material layer (6) may comprise a second fiber layer or, for example, a polymer coating. The laser marking could take place, for example, by burning the surface of the fiber layer (1) or by engraving it. Inside the layer structure, the marks (5) are protected, but detectable with a detector to ensure the authenticity of the material. The marked paper or board is suitable for product packages to be protected against product forgeries.

摘要翻译： 本发明包括一种用于在连续卷材上制造的层结构纸或板（7）上生成识别标记（5）的方法，以及用该方法获得的标记纸和板。 使用这种方法，标记（5）由激光束制成在移动的幅材纤维层（1）上，其后第二层材料（6）随后被重叠，使得标记保持在层内 移动网的结构。 第二材料层（6）可以包括第二纤维层或例如聚合物涂层。 激光打标可以例如通过燃烧纤维层（1）的表面或通过雕刻来进行。 在层结构内部，标记（5）被保护，但是可以用检测器检测以确保材料的真实性。 标记纸或纸板适用于要防止产品伪造的产品包装。
