Ecofont

Ecofont is the name of a TrueType font family, an application program for Windows, and a Dutch business firm. Ecofont Vera Sans (originally called Eco Sans) was developed by SPRANQ in the Netherlands in order to reduce ink consumption when printing. Each character in the font contains tiny holes. SPRANQ claims that this reduces the amount of ink needed by approximately 15 percent when compared to the Vera Sans family on which Ecofont Sans is based. The Ecofont application program (formerly marketed as "Ecofont Professional") inserts small holes in other fonts in order to reduce ink consumption. Both the software and the Ecofont Sans fonts are distributed and sold by Ecofont BV, based in Utrecht.
