Abstract
A web having phosphor particles uniformly distributed on at least one outer surface of the web, the phosphor particles being substantially white or colorless under ambient room light illumination and which upon excitation by ultraviolet light phosphoresces to emit visible radiation having a wavelength between about 400 nanometers and about 500 nanometers for a detactable period after ultraviolet excitation. Imaged webs having phosphor particles uniformly distributed on at least one outer surface thereof may be employed in an imaging process the steps of illuminating the outer surface bearing an image with ultraviolet light during an electrostatographic imaging cycle to cause the phosphor particles to emit visible light, terminating the illumination of the outer surface bearing the image with the ultraviolet light, detecting the visible light emitted by the phosphor particles and altering at least one element of the electrostatographic imaging cycle in response to the detection of the visible light whereby the electrostatographic imaging cycle is disabled.
