Filed:

Feb 19, 2004

Appl. No.:

10/782226

Inventors:

Kenneth E. Conley - Matthews NC, US
Mary E. Conley - Matthews NC, US
Kerry Dwayne Dellinger - Hickory NC, US

International Classification:

G02B 27/10

US Classification:

359619, 359900

Abstract:

A method of producing a lenticular sheet having anisotropic optical properties comprising the steps of providing a body of transparent material having a pair of opposing sides and an index of refraction greater than one; forming a plurality of lenses on the first side of said pair of opposing sides in pre-selected portions of the first side; and wherein the remainder of the first side of said pair of opposing sides outside the pre-selected lens portions is generally flat and transparent. A method of manufacturing a lenticular sheet comprising the steps of producing a transparent sheet by engraving a desired lens pattern over an entire cylinder or flat plate; placing a mask over selected lens areas; metal plating the unmasked areas to a thickness greater than the surface of the masked areas; and cutting the plated areas back to the level of the masked areas.

Abstract:

A method of producing a package from lenticular sheet having anisotropic optical properties comprising the steps of providing a body of transparent material having a pair of opposing sides and an index of refraction greater than one; forming a plurality of lenses on the first side of said pair of opposing sides in pre-selected portions of the first side; forming a pre-determined package design from the lenticular sheet, and wherein the remainder of the first side of said pair of opposing sides outside the pre-selected lens portions is generally flat and transparent. A method of manufacturing a lenticular sheet comprising the steps of producing a transparent sheet by engraving a desired lens pattern over an entire cylinder or flat plate; placing a mask over selected lens areas; metal plating the unmasked areas to a thickness greater than the surface of the masked areas; cutting the plated areas back to the level of the masked areas; and forming a pre-determined package design from the lenticular sheet.
