A different sort of wavy line problem

I did a color separation of this banner the other day for a postcard which was not color separated in Publisher, as Publisher cannot do this and their banner was a .jpeg and the outcome was to be spot color.

Although I ordinarily would not use Xara to make a color separation I can show you the same technique I used in CorelDRAW to make the banner. It is fairly simple to do as well in Xara. If I needed to produce color separations of this, I'd use layers all that is red, black, likewise all that is blue, black but on a separate layers and print the layers independently of each other.

The .xar file gives a description of how to do what I did, the top example is the finished banner.

Cool!
