METHOD OF PROTECTING INK AND PROVIDING ENHANCED BONDING DURING MOLDING OF LENTICULAR LENS SHEETS IN PLASTIC OBJECTS |
摘要 |
A method of fabricating plastic products with an integrated Lenticular lens material that thermally protects the ink layer and outer lens surfaces of the Lenticular insert. A Lenticular lens material is provided with a Lenticular lens layer with an outer surface of optical ridges (22) and an ink layer (28) bonded to a transparent lens layer (24). A thermal protective substrate (30) comprising opaque flexographic ink is applied to the ink layer. The application of the thermal protective substrate is completed using a coating unit of a lithographic press. A Lenticular insert is formed from the coated Lenticular lens material and the insert is positioned within a mold cavity. The thermal protective substrate insulates the ink layer. Concurrently, the portion of the mold adjacent the insert is cooled to a temperature below the deformation temperature of the optical ridges.
