ABSTRACT OF THE DISCLOSURE A temporary badge fabrication system is provided herein. The system comprises a badge for attachment to a wearer, the badge having at least one surface coated with an ambient light sensitive coating thereon which, when exposed to ambient light conditions for a specified period of time, changes to a specified color. An apparatus is further provided for printing information on the badge. The apparatus includes a source of radiation and a printing mask facing the radiation source. The mask comprises an opaque portion and a radiation transmissive por- tion. The radiation transmissive portion contains an information portion. A badge holding means is disposed so that the mask is located between the radiation source and the badge holding means. A means is provided for activating the radiation source for a period of time sufficient to print the information on the badge, preferably, in the specified color. Thus when the badge is exposed to ambient light for the specified period of time the badge changes to the specified color and, preferably, the information is not discernible.
