Patent ID: 7907157

Claim:
A system for enhancing a color image, said image being composed of a plurality of superimposed regular dot patterns upon a planar surface having first and second orthogonal spatial dimensions, each one of said patterns being monochromatic and different in color from that of each other of said patterns, said surface moving in a first direction parallel to said surface, said system comprising: means for intentionally misregistering at least one of said regular dot patterns with respect to at least one of said other of said patterns in directions both parallel to and perpendicular to said first direction to obtain a misregistration pattern; and, means for controlling said misregistration pattern so that said color image is enhanced and so that said misregistration pattern is visually imperceptible; wherein said dot patterns are comprised of a plurality of dots being randomly spaced on said surface in only one of said first and second dimensions and being regularly spaced on said surface along the other of said first and second dimensions.
