Embodiment Construction

[0044] figure 1 is a schematic illustration of a banknote 10 in which the front 12 and rear 14 of the banknote 10 are coded 13 and 15 respectively in the form of the serial number of the banknote. Codes 13 and 15 embody the same serial number, the string "1234".

[0045] Both the code 13 on the obverse side and the code 15 on the reverse side are introduced from the front side 12 of the banknote and are formed by a laser beam so that the engineering effort required to code both sides is kept low s level. In the example mentioned, the code 13 on the front side is formed by a darkened region of the paper of the bank note 10 . The coding 15 on the reverse side is formed by demetallizing plaques 16 that appear to be metallic, eg transfer elements or markings with diffractive optical structures. In this way, under strong contrast, the code formed by demetallization can be clearly distinguished from the metallic environment.

Abstract

The invention relates to a value document, particularly a banknote, comprising an individualizing mark that is applied at least once on the front face and the rear face of the value document, respectively. At least one of the individualizing marks applied to the front face and rear face is applied to the value document by means of a contactless process.

Description

technical field [0001] The invention relates in particular to documents of value such as banknotes. These valuable documents are uniquely marked, such as serial numbers. The invention further relates to a method for producing such value documents. Background technique [0002] Documents of value, such as banknotes, shares, bonds, certificates, vouchers, checks, admission tickets, etc., often have unique markings such as serial numbers. In order to increase the security of valuable documents, this marking is usually used many times. Banknotes, for example, are coded twice so that each side of the banknote is unique. At this time, the numbers on both sides of the banknote are generally the same. [0003] The security of the traditional coding method is relatively low. For example, coding requires white or at least a light background color, and this cannot yet be done on gravure printing. Because if so, ink residues can get into the coding unit, impairing its functionalit...
