The Herwin Wielink colour palette on your map isn't really helping you, with only a single row of relatively dull blues to use, so here it is again with a more balanced colour palette attached to it - to give you more choice with your labels (and only if you want it with this modification).

Hi Brian! :)

The most important thing to remember with lables is contrast. If you turned your map black and white the map itself would be all shades of grey, ranging from a very dark grey to a very pale one. To make text stand out from it chose either a very pale label colour with a very dark glow, or a very dark colour with a very pale glow. The kill-all solution is to use the palest and darkest shades of grey - one for the text and the other for the glow.

Drop shadows don't generally work very well for readability, but can look good on a title sometimes.

Your labels are pretty much mid-tone, which is the most difficult colour to make stand out, even when you intensify the native white glow.

I recommend picking lighter or darker labels, and maybe using an Outer Glow instead of the slightly less tidy Glow, like this.

Or like this.

You could use both on two TEXT sheets - one way for the title and the other way around for the map labels.

Each time I see it I don't think it can look better, but then it improves again.

I think the labels might be a little large now, but again that is personal taste. It depends how large you print or use the map.

Thanks :)

It seemed an unlikely cause. Never had that happen to me before, but I never export without AA.

Ah ha!

I forgot to switch off the antialias.

For some reason you need to have some antialiasing going on.

Try about 20-33%

That definitely shouldn't be happening at zero antialiasing. Please can you report it to TS for me?
