Multiple imaging
First Claim
1. An imaging method which comprises the steps of:
- (a) providing a transparent lenticular sheet having on one face a pattern of lenticles and an opposite face;
(b) imprinting the opposite face of said lenticular sheet with a radiation sensitive ink formulation, wherein said ink formulation is soluble to a predetermined solvent until irradiated with a predetermined radiation, and is rendered insoluble to said predetermined solvent when irradiated with said predetermined radiation;
(c) irradiating portions of said ink formulation with a collimated beam of said predetermined radiation through the transparent lenticular sheet, thereby rendering the irradiated portions insoluble to said predetermined solvent; and
(d) removing the soluble portions of said ink formulation by rinsing with said predetermined solvent.

Abstract
A method and article providing different images from differing viewing angles. The image side of a lenticular sheet is printed with radiation curable inks and cured using a collimated radiation source located at a viewer position with respect to the lenticular surface. Uncured ink is removed from the printed surface, and the resulting clear region of the imaging surface may be processed further in a variety of ways. The clear region may be left unprinted, or printed with a second image different from the first, or a stereoscopic image that combines with its pre-printed mate to form a three dimensional image. The clear region also may be vacuum metallized or chemically plated to form a highly reflective surface.
