Abstract: 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 (SIA, SIB) 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 (RIA, RIB) 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 (MB-A, MC-A, MD-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.

Abstract: 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.
