Patent ID: 7497475

Claim:
A printed substrate comprising: a base having a front surface, and extending along a lateral plane; a first textured pattern formed over a first area of said front surface and having one or more first protrusions extending normally therefrom; a second textured pattern formed over a second area of said front surface and having one or more second protrusions extending normally therefrom; one or more reflective layers over said first and second textured patterns, wherein: said one or more first protrusions of said first textured pattern extend to a first thickness to provide a first pattern height normal to said lateral plane; said one or more second protrusions of said second pattern extend to a second thickness to provide a second pattern height normal to said lateral plane; said second thickness is greater than said first thickness; said second pattern height is greater than said first pattern height; said one or more protrusions of said first textured pattern having a first face surface facing said base, and having a distally opposite second face surface facing away from said base; said first thickness is the distance between said first and second face surfaces; said one or more protrusions of said second textured pattern having a third face surface facing said base, and having a distally opposite fourth face surface facing away from said base; said second thickness is the distance between said third and fourth face surfaces.
