So I am using Photoshop CS5 to make a map of Europe. And I need to make sure the borders of countries don't overlap each other. Is it possible to use clipping masks so that if the borders of one country overlaps the other, the clipping mask will prevent it from spilling over?
If so, does anyone have a tutorial or can anyone tell me how to do that?
I'm also wondering whether Illustrator CS5 might not be better to make sure the borders touch each other and don't overlap.
I think the quickest way of doing this is in Illustrator. If you have overlapping shapes you can get rid of the overlap by using the pathfinder-tool "trim" (Window - Pathfinder - "Trim"-button) when both shapes are selected. That creates a neat border between the shapes. (Obviously works only if the shapes are vectors and not pixel). If they are pixel, using clipping masks in Photoshop might be the quickest way.
Hope this helps.
