<P>PROBLEM TO BE SOLVED: To provide a method of imprinting a texture on a rigid substrate, having an area greater than 50 square centimeters, preferably greater than 200 square centimeters. <P>SOLUTION: A layer of a curable material is wet-coated on a rigid substrate. Thereafter, a flexible stamp is pressurized over the layer of the curable material to imprint the texture. The flexible stamp comprises a bottom zone having a texture profile corresponding to the texture. The bottom zone has Young's Modulus between 0.5 MPa and 3000 MPa, enabling tolerance for microscopic defects while imprinting of the texture. The flexible stamp also comprises a top zone having Young's Modulus between 0.1 GPa and 10 GPa. The top zone enables tolerance for macroscopic defects. Then, the layer of the curable material is cured. Lastly, the flexible stamp is removed. <P>COPYRIGHT: (C)2012,JPO&INPIT |
