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.
Claims20
A redundantly printed security-enhanced document comprising:
- a substrate;
- process color variable indicia representing variable information printed on the substrate, the process color variable indicia comprising a plurality of component colors, each component color manifesting a level greater than a predetermined minimum Signal-to-Noise-ratio threshold relative to the substrate background surrounding the variable indicia when viewed in any of red, green, or blue channels of an additive color model as calculated by a Modified Weber's Fraction equation, such that at least two of the component colors of the process color variable indicia covey a meaning of the variable information when viewed in at least one channel of the additive color model;
- and
- a scratch-off coating covering at least a portion of the process color variable indicia.
A method of producing a redundantly printed security-enhanced document comprising a substrate with process color variable indicia representing variable information printed on the substrate, the process color variable indicia comprising a plurality of component colors, the method comprising:
- determining a variable indicia illuminating light color temperature;
- determining, utilizing an additive color model, a grayscale equivalent level of each component color of the process color variable indicia with each Red, Green, and Blue (RGB) channels;
- determining each of the component colors of the process color variable indicia to ensure that the component colors exhibit a level greater than or equal to a predetermined Signal-to-Noise-ratio threshold relative to a background of the substrate surrounding the variable indicia when viewed in any of red, green, or blue channels of an additive color model as calculated by a Modified Weber's Fraction equation in at least one channel of the additive color model, such that a failure of the printing any one of the component colors of the process color variable indicia does not alter a meaning of the variable information represented by the other component color of the variable indicia;
- sending instructions intended to cause print heads to print the component colors to form the process color variable indicia on the substrate with separate print heads;
- and
- applying a scratch-off coating covering at least a portion of the process color variable indicia.
A document comprising:
- a substrate;
- redundantly printed process color variable indicia conveying variable information printed on the substrate, the process color variable indicum comprising a plurality of component colors with each component color determined with a level greater than a predetermined minimum Signal-to-Noise-ratio threshold relative to a background of the substrate surrounding the variable indicia when viewed in any of red, green, or blue channels of an additive color model as calculated by a Modified Weber's Fraction equation, such that at least two of the component colors comprising the variable indicum coveys a meaning of the variable information of the process color variable indicia when viewed in at least one channel of the additive color model;
- and
- a scratch-off coating covering a portion of the process color variable indicia.
