    • A security feature for an identification document and method for making it provide layers of security, including, for example, tamper evidence, optically variable effects, and personalized information that links the security information to the document and its bearer. The feature is made by printing a first material representing first information on a core layer of the document. This first material at least partially covers the core layer. One example is Xerographic printing of information about the ID document applicant and the applicant's photo. The process then applies a second material representing second information at least partially overlapping the first material, and cures the second material. One example is ink jet printing of personal information with a UV curable ink in the form of a relief pattern on the core layer. Finally, the process applies a laminate layer over the core layer. The laminate layer covers the first and second materials. The first and second materials adhere differently to the laminate and core layers such that removal of the laminate layer from the core layer causes a separation of the first and second materials. The relief pattern is made to give the document a tactile feel as well as create optically variable effects.
    • 用于识别文档的安全特征和用于使其提供安全层的方法,包括例如篡改证据,光学可变效果和将安全信息链接到文档及其承载的个性化信息。 该特征是通过在文档的核心层上打印表示第一信息的第一材料来进行的。 该第一材料至少部分地覆盖芯层。 一个例子是静电印刷关于身份证件申请人和申请人照片的信息。 然后,该过程应用代表与第一材料至少部分重叠的第二信息的第二材料,并且固化第二材料。 一个例子是在核心层上以浮雕图案形式的UV固化油墨喷墨打印个人信息。 最后,该过程在芯层上施加层压层。 层压层覆盖第一和第二材料。 第一和第二材料与层压体和芯层不同地粘附,使得从芯层去除层压层导致第一和第二材料的分离。 浮雕图案是为了使文档具有触感,并产生光学可变的效果。
