Instant ticket redundancy via multi-chromatic indicia
A redundantly printed security-enhanced document, printing method and system are provided for ensuring the meaning of the information imparted by variable indicia printed on documents with removable scratch-off coatings by the redundant printing. By printing the variable indicia with multiple colors, redundancy and integrity of the intended indicia is achieved. Additionally, inverted color indicia countermeasures to pinprick attacks are also disclosed. The redundantly printed document, methods and systems enhance the overall appearance of the redundantly printed document, and reduce the consequences possibly resulting from misprinted variable indicia.
1. A method of printing a redundant security-enhanced document with a substrate and at least one variable indicium, which provides information regarding an intended value of the document, printed directly or indirectly on the substrate using at least two separate color print heads, wherein the at least two separate color print heads each print a separate portion of the same at least one variable indicium, thereby allowing any one print head printed output to be omitted or reduced without loss of information regarding the intended value of the document, the method comprising:
(a) parsing the at least one variable indicium such that the complete information regarding the intended value of the document is printed with at least two separate print heads, wherein the at least two separate print heads image different portions of the at least one variable indicium printed; and
(b) printing the at least one variable indicium with at least two separate print heads, wherein the at least two separate print heads image different portions of the at least one variable indicium with no overlap of printed areas,
thereby providing redundant printing via the separate print heads that print the same information regarding the intended value of the document such that the failure of any one print head to print does not result in the loss of the information regarding the intended value of the document.
2. The method of claim 1 , wherein the at least one variable indicium is printed in two different colors.
3. The method of claim 1 , wherein the at least one variable indicium is printed in process colors.
4. The method of claim 1 further comprising:
(c) printing with at least two separate print heads different portions of the at least one variable indicium with at least two micro-pattern colors.
5. The method of claim 4 , wherein the at least two micro-pattern colors are printed as parallel lines.
6. The method of claim 1 further comprising:
(c) printing with at least two separate print heads different portions of the at least one variable indicium with inverted primary foreground variable indicium colors.
