Patent ID: 8371215

Claim:
A method for manufacturing micro-optic surface design with complex, variable three-dimensional forms, the method comprising: obtaining a step embossing, step imprinting, a chip bonding or a corresponding device capable of patterning the surface of a target substrate; obtaining the target substrate whereto the micro-optic structures shall be patterned; obtaining illumination performance of the target substrate when illuminated by a specified light source, the illumination performance including one or more of: luminance, transmitted light intensity, transmitted light uniformity, or transmitted light radiation pattern; obtaining a plurality of different stamping tools operable with said device, each stamping tool comprising one or more surface relief forms defining one or more micro-optic structures; obtaining an optical design objective based at least in part on current optical properties including the illumination performance of the target substrate and/or a refractive index of the target substrate; selecting a stamping tool from said plurality of stamping tools by said device according to the optical design objective; embossing the target substrate with said selected stamping tool as controlled by said device; and repeating said selecting and embossing steps until the micro-optic surface design has been completed on the substrate.
