A photoluminescent marking that includes a photoluminescent layer and at least one functional overlayer is disclosed. The photoluminescent layer comprises at least one type of photoluminescent material. The at least one functional overlayer is adapted to selectively filter wavelengths of radiation to enhance the daylight observability of a final emission signature of the marking or to prevent the observability with the naked eye of a printed message on the marking. Also methods of making and using the inventive photoluminescent marking are disclosed.
