[How to do this effect: print a logo in white on a dark background?]

The edges of the logo....? Look at the 'N' in 'New York Times'.

 

The real logo looks like this: http://www.nytimes.com/ ?

 

I'm a noob at Paint.net and image manipulation. I can make the logo white on a dark background easily, but the edges are not smooth. It's like I want to paint a white shape, the shape of the logo, on to a dark canvas.

 

Cheers.

But what about the edges? The won't be smooth against the dark background, will they?

The logos (see 'In the press') are white (well, light grey). How can I achieve this effect, given the original colour logos?

 

Many thanks!
