Saving Money and Trees

March 24, 2011

Computer pixels are square, while printer pixels are round. To compensate for the difference, the printer default system usually adds overlapping pixels, using more toner/ink than necessary. Preton CTO Brafman and his team developed Pixel Optimizer to delete unnecessary pixels in text, photos and other visuals before printing.

“We allow a ‘smear' or ‘bleed' effect to cover spaces left by removed pixels,” he says. Savings of toner/ink for text is 35 to 50%; for graphics, the saving is 18%; and for photos, 14%. Yet print quality remains high in both ink-jet and laser printers for corporate and home use. Preton's Elements Identifier identifies each element on a page—text, graphics, photos—and allows different levels of pixel reduction to be applied to each element type.

“There is a saving as soon as the system is installed,” says Preton CEO Ori Eizenberg. PretonSaver can also reduce the number of pages printed by 10% to 20%. “We can save a ton of paper [one tree] for every 200 employees,” Eizenberg says. “Each ton emits 6.3 tons of CO2 during its manufacturing lifecycle. In the bank's case, we can save 2,000 tons of paper, and reduce CO2 by 12,600 tons, saving one tree for every 10 employees.” For more information: www.preton.com, [email protected]
