Abstract

We describe detecting intaglio print on banknotes such that potentially counterfeit banknotes are identified by the absence of intaglio print or the presence of incorrect intaglio print. Intaglio print comprises ridges and grooves on a substrate where ink is applied only to the ridges. A thermal sensor is used to detect the presence of intaglio print by, for example, presenting a banknote to the thermal sensor and moving the banknote relative to that sensor. The banknote may be swiped past the sensor or vice versa. A comparison is made between the output of the thermal sensor and pre-specified information about intaglio printed regions associated with the printed item. Counterfeit detection may also be carried out for passports, postage stamps and other intaglio printed items.

Description

technical field [0001] The present description generally relates to a method and apparatus for detecting counterfeit printed matter. In particular (but by no means limited) to the detection of counterfeit printed matter such as banknotes, passports, postage stamps or other items by detecting gravure printing. Background technique [0002] There is a growing need for automatic detection of potential counterfeit banknotes in different currencies and denominations in a simple, reliable and cost-effective manner. This is desirable, for example, in self-service vending devices that accept banknotes, like self-service kiosks, ticket vending machines, cash dispensers with deposit functionality, self-service currency exchange machines, and the like. [0003] Previously, manual banknote verification methods involved inspection of images, see-through effects such as watermarks and wire alignment marks, the feel and even smell of banknotes. Other known methods rely on semi-explicit f...
