Abstract

Products, such as branding labels and currency, fabricated to include an optical security element. The optical security assembly may include a carrier film or substrate. An image element, e.g., a printed ink layer, is provided on a first surface of the carrier film/substrate, and the optical security assembly further includes an array or plurality of micro lenses on a second surface of the carrier film/substrate opposite the image element. In order to make the registration and print requirements easier, a mask is provided between the printed ink layer to define color pixels, and the printed ink layer is provided in the form of color blocks in a checkboard pattern with each block aligned with a portion of the mask and a subset of the holes or openings that define the viewable color pixels.
