Inside the Digital Paper Labs at Xerox and HP
Xerox tests its digital papers to perform in a variety of normal circumstances, such as an office environment. But it also subjects its papers and hardware to extreme climates, to make certain they function optimally beyond operational norms.
At about 60 degrees at 20% humidity, static electricity can build up, causing sheets to separate incorrectly or even stick together, Kurzweil says. At 80o and 80% humidity, paper swells as it absorbs moisture from the air. Paper curls are the result.
