Abstract
A method of manufacturing an image element array includes: providing a production tool having a surface pattern of ink-receptive elements spaced by areas which are not, the ink-receptive elements defining the array image elements; applying a multi-colored first image formed of a inks to only the ink-receptive elements; and transferring only the portions of the multi-colored first image corresponding to the image elements from the production tool to a substrate. An image element array is formed on the substrate. The production tool surface pattern is configured such that when viewing and image element arrays overlap, each viewing element within an image element array first region directs light from a respective image element or from a respective gap. The viewing angle in the first region directs light from either the array or the gaps.
