Abstract

An infrared image pattern and a gloss effect image pattern are created on a recording medium by electronically creating a first electronic pattern ink, the first electronic pattern ink including a first color and including holes, the holes representing areas in the first electronic pattern ink wherein the first color is absent; electronically creating a second electronic pattern ink using the first color and including filled holes, the filled holes of the second electronic pattern ink representing areas in the second electronic pattern ink filled with a second color, the second color having infrared properties opposite of infrared properties of the recording medium; electronically creating an electronic image region; electronically painting, using the first electronic pattern ink, a background of the electronic image region; electronically painting, using the second electronic pattern ink, a foreground of the electronic image region; and rendering, using marking materials, the electronic image region on the recording medium such that the electronic image region is visible when a relative angle between an observer's viewing angle and an angle of illuminating the recording medium by an illumination source is a first angle, the electronic image region not having the predetermined portion of the holes painted with the second color being not visible when the relative angle between the observer's viewing angle and the angle of illuminating the recording medium by the illumination source is a second angle, the second angle being not equal to the first angle and such that the recording medium is only visible through the holes not painted with the second color when viewing the recording medium using infrared illumination.
