i have about 35-40 scans/illustrations for book.
Style is like attached image
the book must be printed in 2 colours.
how can i (easy) convert images to black+pantone?
i tried select->color range. it works good with black, but not blue. how to get good channel for blue and blue tints?
and how to find best match blue pantone? because in tints (light blue) colors became too warm (violet) or too dirty
