<pre wrap="">Must they be .jpgs? You'll get a lot of "sharp edge" artefacts using the
.jpg format on a map. In theory at least (and in practice whenever I've

Bear in mind these are printed maps, not rasterised vector maps. We tried

No - you've done the tests and in this case evidently .jpg wins. I'm
surprised, but I've seen that happen before. I suppose it depends on
just how sharp the "sharp edges" were on your images.<br>
