    • A method of authenticating a document includes providing a document having a substrate comprising an optical brightener; printing a background with a ultraviolet (UV) absorbing material on the substrate comprising a first pattern of lines having a first frequency and a first orientation; printing a security mark with the UV material on the substrate comprising a second pattern of lines having a second frequency or a second orientation or both; placing a lenticular lens over the security mark and background; illuminating the security mark and background through the lenticular lens with UV light; orienting the lenticular lens to match either the first orientation or the second orientation; and authenticating the document if the security mark matches a predetermined security mark.
    • 认证文件的方法包括提供具有包括荧光增白剂的基底的文件; 在衬底上用紫外线(UV)吸收材料印刷背景,包括具有第一频率和第一取向的线的第一图案; 用衬底上的UV材料印刷安全标记,其包括具有第二频率或第二取向或两者的第二线条图案; 将双凸透镜放在安全标记和背景上; 用紫外线照射透镜透镜的安全标记和背景; 定向双凸透镜以匹配第一取向或第二取向; 并且如果安全标记与预定的安全标记相匹配,则认证文档。
