How tiny gaps cut a page’s ink use
A printer does not lay down a continuous sheet of color to make a letter. It builds the letter from many small marks: ink droplets in an inkjet printer or toner particles in a laser printer. Ecofont alters the letter shapes so that some of their interior area is left blank. The words remain readable, but the printer has less of each character to fill.
The trick depends on where the gaps are placed. A hole through a thick stroke removes more printed area than one near a thin edge, but too many or too-large holes can make a character look weak or harder to recognize. The design has to reduce filled space while preserving the familiar outline that lets readers identify each letter quickly.
Why the savings depend on the job
The reduction applies to the characters printed in Ecofont, not to every part of a document. A page with large headings, images, colored graphics, or text in another font will not benefit in the same way. Printer settings, font size, and the mix of letters also affect how much material is actually used, so the advertised reduction is an estimate rather than a fixed result for every print run.
That makes Ecofont a small design intervention rather than a change to the printer: the same text can be sent to the same machine, but its letterforms ask the machine to deposit less material. The practical test is whether the print remains clear at the size people need—because a saving is useful only if the page is still comfortable to read.
