A frequent problem in photoreceptor production is the overspray of bar code ink onto active sections or areas of the photoreceptor being labeled. This causes print quality defects that result in product reject. This disclosure proposes the addition of small amounts of a fluorescent dye be added to the ink that can be seen by a black light/photosensor arrangement that is sensitive to the fluorescent wavelength of the dye.
