Abstract

Comprende una primera etapa de recepcion de una informacion entregada por un cliente y análisis técnico de la misma. Comprende asimismo una segunda etapa de confeccion de fotocromos y colores planos tomando de base la escala ôPantoneö y la parte CMYK del archivo original. Comprende una tercera etapa de transferencia de dicha escala ôPantoneö a una escala propia y obtencion de colores planos con dicha escala. Comprende una cuarta etapa de reproduccion y correccion de colores y de la escala tonal hasta un 97% de acercamiento y una quinta etapa de calibracion por software y retoque manual de dichos colores y escala tonal hasta un 99% de acercamiento. Por ultimo comprende una sexta etapa de confeccion de las imágenes finales de grabado del cilindro de impresion y almacenado en un medio adecuado. La tercera etapa comprende un primer paso de seleccion de aquellos colores que resultan más proximos al original; un segundo paso donde se aplican curvas secundarias para lograr la compensacion tonal y obtener los mediotonos de los colores especiales y convertirlos en CMYK y un tercer paso, donde se aplican curvas terciarias para lograr cortes adecuados de degrades. En las etapas cuarta y quinta, el valor tonal y de color alcanzado surge de contemplar perfiles ICC de partida y de destino con una calibracion adecuada para pruebas de color, donde el perfil ICC de partida será el de las tintas de gamut ampliado que se utilizan mientras que el perfil ICC de destino será, preferentemente, un perfil normalizado.
