Abstract
An apparatus for creating copy restrictive media is disclosed comprising a linear array (20) comprised of at least two spatially distributed light sources (22) and an aperture mask (28) for forming two or more micro-light sources from the light sources (22). An optical element (32) focuses light from the micro-light sources onto a media (40) moving relative to the linear array (20). An encoder (16) turns the light sources (22) on and off at regular intervals relating to movement of the media (40).
