Abstract

ORGANOS DE MEDICION DE LOS SISTEMAS DE CIRCUITO CERRADO DE CONTROL CORRECCION DE LA IMPRESION PARA MAQUINAS DE IMPRIMIR OFFSET. CARACTERIZADOS PORQUE LOS VALORES DE LA MEDICION SON AMPLIFICADOS, CONMUTADOS ANALOGICAMENTE, CONVERTIDOS DE ANALOGICO A DIGITAL Y LUEGO MICROPROCESADOS, PARA SER COMPARADOS CON VALORES PATRON ESTABLECIDOS EN UN PROGRAMA DE MEMORIA PREVISTO PARA CADA UNA DE LAS VALVULAS QUE REGULAN LOS TINTEROS DE CADA UNO DE LOS CUERPOS DE IMPRESION, Y PORQUE LA LECTURA SE TOMA SOBRE UNA MANCHA DE COLOR, DESCOMPONIENDOSE EN TRES VARIABLES, CADA UNA DE LAS CUALES CORRESPONDE A UNO DE LOS TRES COLORES BASICOS DEL ESPECTRO VISIBLE EN QUE ES DIFRACTADA LA LUZ.
