Abstract (en)
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.
