1. A document, comprising a non-magnetic substrate; a first colorant mixture printed as a first repeating distraction pattern comprising a first colorant combination in mosaic combination with a second colorant combination upon the substrate, the first colorant mixture further comprising a magnetic ink; and a second colorant mixture printed as a second repeating distraction pattern comprising a third colorant combination in mosaic combination with a fourth colorant combination upon the substrate in substantially close spatial proximity to the printed first colorant mixture, wherein the second colorant mixture consists essentially of one or more non-magnetic inks and exhibits properties of both low visual contrast and high magnetic contrast against the first colorant mixture, such that the resultant printed substrate does not reveal the first repeating distraction pattern to the human eye, but will reveal the first repeating distraction pattern to a magnetic image reader.
