The image on printing-out paper appears during exposure, so no developer is required. The exposure is made by contact under ultraviolet light such as sunlight, mercury vapor or black light sources. The exposure time varies from a few minutes to several hours. The processing which includes gold toning formulas and hypo fixing produces fine museum quality prints.
