Abstract

Un método fotográfico para imprimir una estructura de pantalla para un tubo de rayos catódicos que comprende un soporte de pantalla y un diseño de distribución de depósitos de material luminiscente en el soporte de pantalla, y una carátula perforada fijada en una posición separada a distancia del soporte de pantalla, mediante el recurso de depositar en el soporte de pantalla un revestimiento fotosensible, exponer o impresionar dicho revestimiento, a través de las aberturas practicada en dicha carátula, a la luz que viene de una fuente de luz de pequeña área y luego que viene de una fuente de luz de pequeña área, y luego revelar el revestimiento así impresionado, caracterizado dicho método por el hecho de exponerse el revestimiento fotosensible de una zona central de la pantalla a una fuente de luz colocada en posición en un centro de color de segundo orden respecto al soporte de pantalla y exponerse al revestimiento fotosensible de una zona exterior de la pantalla a una fuente de luz colocada en posición en un centro de color de primer orden respecto al soporte de pantalla.
