Abstract: The invention generally relates to a security sheet or document having one or more enhanced watermarks. In one exemplary embodiment, the inventive security sheet or document is a single-ply paper that is made up of a paper layer including one or more watermarks, and a micro-optic security device {e.g., a patch or thread) that at least partially covers an upper or face portion of the watermark(s). The overlying patch or thread increases the durability of the watermark(s), thereby allowing for the watermark(s) as well as reduced fiber density areas therein to be made larger, and further allowing for the reduced fiber density areas to be made thinner. In a preferred embodiment, the micro-optic security device projects one or more synthetic images that coordinate or link in with the watermark design(s). In a more preferred embodiment, the micro-optic security device offers a machine detectable/readable feature in the form of enhanced IR- brightness, especially when measured in transmission. As will be readily appreciated, the inventive security sheet or document offers greatly improved counterfeit-resistance.

Abstract translation: 本发明总体上涉及具有一个或多个增强水印的安全薄片或文件。 在一个示例性实施例中，本发明的安全薄片或文件是由包括一个或多个水印的纸层和微型光学安全装置（例如，补丁或线程）组成的单层纸，该微型光学安全装置至少部分地 覆盖水印的上部或面部部分。 覆盖的贴片或线增加了水印的耐久性，由此允许水印以及其中的减少的纤维密度区域变得更大，并且进一步允许减小的纤维密度区域变得更薄。 在优选实施例中，微型光学安全装置投射与水印设计协调或链接的一个或多个合成图像。 在更优选的实施例中，微型光学安全装置以增强的IR-亮度的形式提供机器可检测/可读的特征，尤其是当在传输中测量时。 如容易理解的那样，本发明的安全薄片或文件提供了大大改进的防伪性。
