Instant ticket redundancy via multi-chromatic indicia

A method of producing a redundantly printed security-enhanced document comprising a substrate and at least two different printed variable indicia directly or indirectly printed on the substrate having a general area, the variable indicia being imaged indicia which provide variable information regarding the document, the at least two different printed variable indicia having at least one component color in the same general area of the substrate as at least second printed variable indicia printed of a different component color, the at least first printed variable indicia component color and the at least second printed variable indicia different component color being present so as to be printed in register to produce resulting redundant process color indicia, the method comprising:

• (a) measuring the grayscale equivalent level of the substrate surface on which the variable indicia is to be imaged;
• (b) measuring the grayscale equivalent level of the component colors of the variable indicia;
• (c) printing each component color of the variable indicia with separate physically distinct print heads;
• (d) selecting the resultant printed process color indicia so that the resultant printed process color indicia maintains a grayscale equivalent level greater than or equal to the measured grayscale equivalent level of the substrate surface plus an additional contrast delta of 15%;
• and
• (e) selecting each of the at least two separate printed component colors or combination of component colors of the variable indicia so that each of the at least two separate printed component colors or combination of component colors of the variable indicia exhibit a grayscale equivalent level greater than or equal to the measured grayscale equivalent level of the substrate surface plus an additional contrast delta of 15%;
• such that the failure of the printing of one portion of either or any of the at least two printed component colors of the variable indicia does not alter a meaning of the information of the document represented by the variable indicia on the redundantly printed security-enhanced document.
