    • A printing machine for printing security features onto a web. The machine has a first printing cylinder defining a first circumference and carrying a first number (m) of rows of first image elements, each adjacent row of first image elements having a first circumferential separation. The machine also has a second printing cylinder defining a second circumference, different to the first circumference, and carrying a second number (n) of rows of second image elements, different to the first number (m) of rows, where each adjacent row of second image elements has the same first circumferential separation as adjacent rows of first image elements. The printing cylinders are operable to print the first and second image elements in registration on a web so that composite security features are created on the web from the first and second image elements.
    • 一种用于将安全功能打印到网络上的打印机。 机器具有限定第一圆周并且承载第一数量(m)行的第一图像元素的第一印刷滚筒,每个相邻的第一图像元件行具有第一周向间隔。 机器还具有限定与第一圆周不同的第二圆周并且承载不同于行的第一数量(m)的第二数量(n)行的第二图像元素的第二印刷滚筒,其中每个相邻行 第二图像元件与第一图像元素的相邻行具有相同的第一周向间隔。 印刷滚筒可操作以将第一和第二图像元素在纸张上登记打印,从而在第一和第二图像元件的网上创建复合的安全特征。

    • A device for validating a secure tag comprises: an optical source (such as one or more LEDs); a processor coupled to the optical source for controlling emissions therefrom; and a luminescence detector coupled to the processor. The processor is programmed to control the optical source to create a first and a second pulse sequence having first and second excitation parameters respectfully. The processor is also programmed to control the luminescence detector to measure first and second luminescence in response to the first and second pulse sequences respectively. The processor is programmed to validate the secure tag in the event that the first and second luminescence meet an acceptance criterion. A method of validating a secure tag is also described.
    • 用于验证安全标签的装置包括:光源(诸如一个或多个LED); 耦合到光源的处理器,用于控制从其发射的处理器; 以及耦合到处理器的发光检测器。 处理器被编程以控制光源以产生具有第一和第二激励参数的第一和第二脉冲序列。 处理器还被编程为控制发光检测器以分别响应于第一和第二脉冲序列来测量第一和第二发光。 处理器被编程为在第一和第二发光满足接受标准的情况下验证安全标签。 还描述了验证安全标签的方法。
