Abstract
La presente invención se refiere a un método para el grabado fotomecánico de una imagen de medio tono, en que un material fotosensible de haluro de plata expusto a la imagen para formar imágenes de puntos de medio tono, se revela en una solución reveladora alcalina y la imagen de plata revelada se somete al grabado de puntos por medio de una solución oxidante de halogenuro de plata, la mejora que consiste de asociar en relación de reacción una emulsión de halogenuro de plata de grano fino y alto contenido de cloruro en un material fotosensible con un compuesto seleccionado del grupo de los compuestos de la sal de tiazolio, compuestos tiazol y los compuestos pirazol, en una cantidad suficiente para que se ocasione la reducción en el área de los puntos, sin causar una reducción importante de los puntos pequeños.
