Using Garamond instead of Times Would Save @USAgov $400,000,000 a Year
Long story short, a 14-year-old student in Pittsburgh was able to pull of a real world science experiment to see how much ink would be saved by using a typeface with thinner strokes.
Collecting random samples of teachers' handouts, Suvir concentrated on the most commonly used characters (e, t, a, o and r). First, he charted how often each character was used in four different typefaces: Garamond, Times New Roman, Century Gothic and Comic Sans. Then he measured how much ink was used for each letter, using a commercial tool called APFill® Ink Coverage Software.
Next he enlarged the letters, printed them and cut them out on cardstock paper to weigh them to verify his findings. He did three trials for each letter, graphing the ink usage for each font. From this analysis, Suvir figured out that by using Garamond with its thinner strokes, his school district could reduce its ink consumption by 24%, and in turn save as much as $21,000 annually.
There are some snafus relating to real world gov't document printing in that many more documents are digital nowadays, but Suvir argues there is still enough of a demand that some savings could be made. Our only question is: aren't most high-volume printers laser/toner based and much cheaper than the ridiculously high refill cost of ink-jet printers?
Either way, it made CNN.
