    • There is described a process of measuring print-to-print register of a multicolour print (A-D) provided in an effective printed area (EPA) of the surface of printed material, which multicolour print (A-D) is formed on the printed material by means of one or more printing presses and includes at least a first pattern (A) and a second pattern (B) distinguishable from the first pattern (A), the effective printed area (EPA) being provided with a matrix arrangement of individual imprints (P) which are each provided with the multicolour print (A-D) and are repeated over the surface of the effective printed area (EPA) along a pattern of rows and columns. Measurement of an actual print-to-print register between the first and second patterns (A, B), as reflected on the printed material, is derived from processing and finding a correspondence between (i) at least one sample image (SI A , SI B ) of the printed material covering at least a portion of the first and second patterns (A, B), and (ii) at least one corresponding reference image (RI A , RI B ) generated using prepress design data of the first and second patterns (A, B). Furthermore, the process is repeated for multiple ones of the individual imprints (P) so as to derive a set of multiple measurements of the actual print- to-print register between the first and second patterns (A, B) at various imprint locations over the effective printed area (EPA), which set of multiple measurements is mapped into a corresponding print-to-print register map (M B-A , M C-A , M D-A ,...) that is representative of print-to-print register deviations at the various imprint locations. Also described is a measuring device for carrying out this process and a process of measuring and correcting print-to-print register of a multicolour print.
    • 描述了一种测量设置在印刷材料表面的有效印刷区域(EPA)中的多色印刷(AD)的印刷到印刷寄存器的过程,所述多色印刷(AD) 借助于一个或多个印刷机在印刷材料上形成,并且至少包括可与第一图案(A)区分的第一图案(A)和第二图案(B),有效印刷区域(EPA)设置有 个别印记(P)的矩阵排列,每个印记设置有多色印记(AD)并且沿着行和列的图案在有效印刷区域(EPA)的表面上重复。 在印刷材料上反映的第一和第二图案(A,B)之间的实际印刷到印刷寄存器的测量是从处理和找出(i)至少一个样本图像(SI ,...),它代表各个压印位置处的打印到打印偏差。 还描述了用于执行该过程的测量装置以及测量和校正多色印刷品的印刷到印刷记录的过程。

    • There is described a method of checking producibility of a composite security design of a security document, in particular of a composite banknote design, on a line of production equipment, the composite security design being the product of a combination of multiple sets of design features that are to be provided on a substrate as a result of a plurality of successive production operations carried out by means of the line of production equipment. The method comprises the steps of (a) providing digital design data representative of the composite security design of the security document, (b) modelizing, in a computer environment, the line of production equipment by means of which the composite security design is intended to be produced, (c) performing a computer simulation of production results of the plurality of successive production operations on the basis of the digital design data and the modelized line of production equipment, and (d) evaluating the computer simulated production results and determining, on the basis of these computer simulated production results, whether the composite security design can be produced on the line of production equipment.
