Can you post an example of your map, if it is big, part of it will do. How it is made will influence the method.
For example this is using a Gimp plugin g'mic http://www.gmic.eu It will add borders (in black) between colours. Which might be sufficient. But any existing outlines will be reinforced, which might not be so good.
