Abstract

UN PROCEDIMIENTO DE IMPRESION ELECTROSTATICA Y CORRESPONDIENTE FORMULACION DE REVELADOR LIQUIDO. SE DESCRIBE UN PROCEDIMIENTO PARA REPONER UN REVELADOR LIQUIDO, Y UN REVELADOR LIQUIDO PRODUCIDO POR ESTE PROCEDIMIENTO, QUE COMPRENDE TRANSFERIR UNA PRIMERA COMPOSICION QUE COMPRENDE UN LIQUIDO PORTADOR Y UN DIRECTOR DE CARGA DENTRO DEL REVELADOR LIQUIDO Y TRANSFERIR UNA SEGUNDA COMPOSICION, QUE COMPRENDE PARTICULAS DE VIRADOR, LIQUIDO POSTADOR Y DIRECTOR DE CARGA, AL REVELADOR LIQUIDO. LA CANTIDAD DE DIRECTOR DE CARGA EN CADA UNA DE LAS COMPOSICIONES PRIMERA Y SEGUNDA ESTA EN UNA RELACION PREDETERMINADA QUE DA COMO RESULTADO UN NIVEL CONSTANTE DE DIRECTOR DE CARGA EN EL REVELADOR LIQUIDO CUANDO EL REVELADOR LIQUIDO SE UTILIZA EN UN PROCESO ELECTROSTATICO DE FOTOCOPIADO O IMPRESION.
