Abstract

A method for implementing a secure printing campaign to thwart counterfeiting is provided. The method includes the steps of selecting a first secure print technology and a second secure print technology that is distinct from the first secure print technology, selecting a first secure print variable for the first secure print technology and a second secure print variable for the second secure print technology, and establishing a first plurality of discrete values for the first secure print variable and a second plurality of discrete values for the second secure print variable.

Claims

1. A method implementing a secure printing campaign to thwart counterfeiting, comprising steps of:

selecting a first secure print technology and a second secure print technology distinct from the first secure print technology;

selecting a first secure print variable for the first secure print technology and a second secure print variable for the second secure print technology; and

establishing a first plurality of discrete values for the first secure print variable and a second plurality of discrete values for the second secure print variable;

selecting first single value from the first plurality of discrete values and a second single value from the second plurality of discrete values; and

printing a first marking and a second marking on a target item, said first marking defined by the first single value, said second marking defined by the second single value.

2. The method of claim 1, further comprising the step of establishing a key which includes identification of the target item, the first marking, and the second marking such that, upon matching with the key, the target item is authenticated.

3. The method of claim 2, further comprising steps of:

detecting a purported target item; and

detecting both the first single value and the second single value from the purported target item to authenticate the purported target item as the target item.

4. The method of claim 1, wherein the first secure print variable and the second secure print variable are the same.

5. The method of claim 1, wherein the first secure print variable and the second secure print variable are different.

6. The method of claim 1, wherein at least one of the first secure print variable or the second secure print variable is a multi-dimensional variable.

7. The method of claim 1, wherein the step of establishing a first plurality of discrete values and a second plurality of discrete values includes a preliminary step of determining a range encompassing at least one of the first secure print variable or the second secure print variable.

8. The method of claim 7, wherein at least one of the first plurality of discrete values or the second plurality of discrete values includes a maximum number of discrete values within the range.

9. The method of claim 1, wherein at least one of the first marking or the second marking is a covert marking.

10. The method of claim 1, wherein at least one of the first marking or the second marking is an overt marking.

11. A method implementing a secure printing campaign to thwart counterfeiting, comprising steps of:

selecting three or more secure print technologies;

selecting at least one secure print variable for each of the secure print technologies; and

establishing a plurality of discrete values for each at least one secure print variable;

selecting a single value from each plurality of discrete values; and

printing a plurality of marking on a target item, each marking defined by a corresponding single value.

12. The method of claim 11, further comprising the step of establishing a key which includes identification of the target item and the plurality of markings such that, upon matching with the key, the target item is authenticated.

13. The method of claim 12, further comprising steps of:

detecting a purported target item; and

detecting enough single values from the purported target item to authenticate the purported target item as the target item.

14. The method of claim 11, wherein the at least one secure print variable for each of the secure print technologies are each different.

15. The method of claim 11, wherein at least one of the secure print variables is a multi-dimensional variable.

16. The method of claim 11, wherein the step of establishing a plurality of discrete values for each at least one secure print variable includes a preliminary step of determining a range encompassing each at least one secure print variable.

17. The method of claim 16, wherein at least one of the plurality of discrete values includes a maximum number of discrete values within the range.

18. The method of claim 11, wherein the step of printing a plurality of markings on a target item further includes steps of:

creating a print template having a plurality of regions configured to accept variable data items;

generating a plurality of variable data items, wherein each variable data item is derived from at least one single value;

adding the plurality variable data items to the print template; and

printing the print template.

19. The method of claim 11, wherein at least one of the plurality of markings is a covert marking.

20. The method of claim 11, wherein at least one of the plurality of markings is an overt marking.
