Abstract

UNA MASCARA QUE SE UTILIZA PARA MONTAR UNA HOJA SENSIBLE, TAL COMO UNA PLACA DE IMPRESION, SOBRE LA SUPERFICIE DE UN TAMBOR DE EXPOSICION. LA MASCARA, QUE ACTUA COMO INTERMEDIARIA ENTRE EL TAMBOR DE EXPOSICION Y LA PLACA DE IMPRESION, ES UNA HOJA FLEXIBLE, CON UNA SUPERFICIE SUPERIOR Y UNA INFERIOR, MONTADA ALREDEDOR DEL TAMBOR DE EXPOSICION. UNA HENDIDURA FORMADA DENTRO DE LA SUPERFICIE SUPERIOR DE LA HOJA FLEXIBLE SE UTILIZA PARA ASEGURAR LA PLACA DE IMPRESION MEDIANTE UN VACIO. UN PASO FORMADO DENTRO DE LA HOJA FLEXIBLE CONECTA LA HENDIDURA A LA SUPERFICIE INFERIOR Y RECIBE UN VACIO DEL TAMBOR DE EXPOSICION. EN EL TAMBOR DE EXPOSICION DE MONTAN PLACAS DE DIFERENTES TAMAÑOS MEDIANTE LA UTILIZACION DE MASCARAS INTERCAMBIABLES CON LOS TAMAÑOS CORRESPONDIENTES.
