A micro-optic security device () includes a planar array of micro-optic focusing elements () and a first arrangement of image icons (), wherein each image icon () of the first arrangement of image icons includes a region of light-cured material. Further, the first arrangement of image icons is visible () through the planar array of micro-optic focusing elements across a first predetermined range of viewing angles relative to the micro-optic security device, and the first arrangement of image icons is not visible () through the planar array of micro-optic focusing elements across a second pre-determined range of viewing angles relative to the micro-optic security device.
