Abstract
A micro-optic film structure that alone or together with a security document or label projects images spatially coordinated with static images and/or other projected images is provided. The inventive film structure is made up of: (a) one or more polymer film materials; (b) one or more planar arrangements of primary image icons; (c) one or more planar arrangements of focusing elements or lenses; and (d) one or more secondary image icons. The planar arrangements are configured such that when a planar arrangement of primary image icons is viewed through a planar arrangement of focusing elements or lenses, one or more first synthetic images are projected. The secondary image icons appear as static and/or other projected images. These images are spatially coordinated with the first synthetic image(s) projected by the film structure, such that when simultaneously displayed therewith, they visually enhance or cancel the projected first synthetic image(s).
