    • The invention relates to a document of value consisting of a substrate of predetermined surface area with a printed image visible to the naked eye and a marking in the form of characters, patterns or the like at least partly superimposed on the printed image. The marking is represented by a feature substance having at least one mechanically detectable physical property and extends over the predominant part of the surface of the document. The marking additionally has a given measurable regularity which makes it possible, by mechanical scanning of the marking, to detect the correctness of the distribution and recognize gaps or added partial elements of other authentic documents as disturbances.
    • 本发明涉及一种价值的文件,该文件包括具有肉眼可见的印刷图像的预定表面区域的基底和至少部分地叠加在打印图像上的字符,图案等形式的标记。 标记由具有至少一种可机械检测的物理性质的特征物质表示,并且在文件的表面的主要部分上延伸。 该标记另外具有给定的可测量的规律性,这使得可以通过标记的机械扫描来检测分布的正确性,并识别其他真实文件的间隙或添加的部分元素作为干扰。
