Abstract

Proceso para la preparación de películas positivas o negativas para su uso en impresión multicolor, que comprende la utilización de una película negativa para la separación de color a partir de una positiva de color utilizada como original, caracterizado porque sobre una película de tono continuo del tipo Pan se ha preparado un negativo de separación de color que posee una gama de densidades no superiores a 1.0, preparando sobre una película de tono continuo ortocromático una máscara gris a partir de negativo de separación del color por medio de exposición en contacto con la misma.
