The significant savings are achieved by printing your text with holes in it. The white circles are placed intelligently. As a result, the output is pleasant to read. Ecofont software is not a font, it works with existing fonts. It is easy to implement without the need to change your house style and your existing documents and forms.
“Ecofont’s new software goes one better, letting people use “normal” fonts on screen and inserting the holes only at print time - and then only for small type sizes, where they are less apparent. Ecofont recently picked up a
European Environmental Design Award for its work.”
