Ecofont: The prints we make for our 'daily use' not only use paper, but also ink.

Dutch marketing and communications company Spranq has come up with a novel and free way of slashing printer ink costs by developing a font with holes in it.

I’d be curious to find out how much ink would actually be saved with this. Sure it looks like it would be a ton if you look at the large example on their website, but if you reduce that to their 9 or 10 point size as they recommend, are the circles still there or do they just get “filled in” when you do the size reduction? Any time you make something smaller, you lose detail, and you can only get so small before those holes disappear completely.
