Abstract
PROCEDIMIENTO ELECTROGRAFICO DE FORMACION DE IMAGENES. CONSISTE EN REALIZAR LA CARGA DEL ELEMENTO FORMADOR DE IMAGEN EN DOS PARTES. AL PRINCIPIO SE CARGA UN VALOR PREDETERMINADO, PARA EXPONER A CONTINUACION DICHO ELEMENTO FORMADOR DE IMAGEN A LA LUZ; DESPUES SE VUELVE A CARGAR EN UN VALOR INFERIOR AL PRIMERO, PARA EXPONERLO DE NUEVO A LA LUZ Y REVELAR LA IMAGEN LATENTE, PASANDOLA A UNA HOJA DE COPIA. DE APLICACION EN MAQUINAS FOTOCOPIADORAS.
