Methods for designing and producing a security feature are provided. In general, the present disclosure provides methods of designing a printed image in a security feature, the security feature comprising an array of optical elements overlaying the printed image, wherein the printed image comprises a two dimensional matrix of rows and columns of pixels, the method comprising; correcting for a mismatch between the pixels of the printed image and the array of optical elements by doing one or more of: adding one or more pixels; removing one or more pixels; and moving one or more pixels.

A display body includes a first surface, a second surface, a first optical component, and a second optical component. The first surface includes a first optical surface and a second optical surface. First light is incident on the first surface from an observation side. The second surface is located opposite to the observation side with respect to the first surface. Second light is incident on the second surface from a side opposite to the observation side with respect to the second surface. The first optical component forms first information, which is displayed on the observation side, from the first light received on the first optical surface. The second optical component receives the second light transmitted through the second surface, forms second information, which is displayed on the observation side, from the second light, and emits the second information from the second optical surface.
