What’s an eco friendly font, anyway? One that requires less ink when printed, say Grey advertising agency and UK stationery company Ryman, who’ve teamed up to offer “the world’s most beautiful sustainable font” for free. Ryman Eco is a font comprised of a series of lines, as opposed to a solid line, a distinction indecipherable at font sizes up to 10 pt., but purported to save 30% in ink usage. As for what distinguishes Ryman Eco from other ‘green’ fonts, like 2009′s Ecofont, for instance, Grey and type designer Dan Rhatigan claim it requires less ink still, and looks beautiful even when enlarged. No argument here.
