A marketing firm from the Netherlands called SPRANQ has developed the Ecofont. Yes, an eco friendly font! Using this font, when printing, uses 20% less ink by the genius idea to cut tiny holes out of each letter to save the amount of ink used to print at the same time as maintaining the readability of the font. Hats off to them!
It is free to use and free to download, so I suggest you start using this font immediately. I just did! A preview of the font is below.
