Abstract
A redundantly printed security-enhanced document, printing method, and system for better ensuring that the meaning of the information imparted by variable indicia printed by redundant printing indicia on a document protected by a removable Scratch-Off Coating (SOC). By printing the variable indicia with multiple colors, redundancy and integrity of the intended indicia is achieved relative to the perception of human eye photoreceptor cones. The redundantly printed document, methods, and systems enhance the overall appearance of the redundantly printed document, and reduce possible consequences resulting from misprinted variable indicia.

A method of producing a redundantly printed security-enhanced document comprising a substrate and process color variable indicia representing variable information printed on the substrate, the process color variable indicia comprising a plurality of different component colors, the method comprising:
- verifying the plurality of different component colors for the process color variable indicia by:
- determining a variable indicia illuminating light color temperature,
- determining, using the variable indicia illuminating light color temperature and red, green, and blue channels of an additive color model, an average grayscale equivalent level of each of the plurality of different component colors,
- attenuating the determined average grayscale equivalent level of each of the plurality of different component colors with at least one value for at least one of the red, green, or blue channels of the additive color model,
- determining which of the plurality of different component colors exhibit an attenuated grayscale equivalent level greater than or equal to a predetermined minimum threshold in at least one of the red, green, or blue channels of the additive color model, and
- ensuring that a minimum of two of the plurality of different component colors to be used for the process color variable indicia each exhibit an attenuated grayscale equivalent level greater than or equal to the predetermined minimum threshold in at least one of the red, green, or blue channels of the additive color model, and such that a failure of printing of any one of the component colors for the process color variable indicia does not alter the meaning of the variable information represented by the other selected component color;
- sending instructions intended to cause separate print heads to print the selected component colors to form the process color variable indicia on the substrate;
- and
- applying a scratch-off coating covering at least a portion of the process color variable indicia on the substrate.
