A method for manufacturing low-cost electroluminescent (EL) lamps is disclosed. The method of the present invention includes the first step of die cutting, embossing or chemically etching a metal foil to form one or more rear capacitive electrodes. Next, the capacitive electrodes are bonded to a paper core stock which is coupled to a precisely positioned indexing system. In the third step, a layer of EL phosphor ink is applied to the capacitive electrodes to precisely form the areas of illumination. In step four, a layer of conductive ITO ink is applied to cover the layer of EL phosphor ink. Next, in step five a transparent polyester film or ultraviolet activated dielectric coating is applied to the entire surface of the lamp. Finally, in step six electrical terminations are provided to the rear capacitive electrode and the layer of conductive ITO ink.
