Abstract
A system is provided for counterfeiting countermeasures, the system comprising: a first authenticity indicator disposed in a print substrate coating; a second authenticity indicator disposed in a print generating matrix; a print pattern comprising the print generating matrix disposed upon the print substrate coating; a detector configured to detect the first and the second authenticity indicators in a portion of the print pattern within the field of the detector.
Claims17
A system for counterfeiting countermeasures, the system comprising:
- a first authenticity indicator disposed in a print substrate coating at a concentration within a preprogrammed window of first authenticity indicator concentrations;
- a second authenticity indicator disposed in a print generating matrix at a concentration within a preprogrammed window of second authenticity indicator concentrations;
- a print pattern comprising said print generating matrix disposed upon said print substrate coating;
- a detector configured to detect said first and said second authenticity indicators in a portion of said print pattern within the field of the detector and to determine if both said first authenticity indicator is at said concentration within said preprogrammed window of first authenticity indicator concentrations and said second authenticity indicator is at said concentration within said preprogrammed window of second authenticity indicator concentrations.
1 more element
The method of certifying the authenticity of a printed pattern, said method comprising:
- providing a substrate coating layer having a first authenticity indicator disposed therein;
- applying a pattern to said substrate coating layer, said pattern comprising a second authenticity indicator disposed within a matrix;
- applying a detector to a said pattern, said detector being a preprogrammed detector configured to detect preprogrammed threshold levels of said first and second authenticity indicators, and providing an output indicating the presence of said first and said second authenticity indicators.
