'Blue Noise' Is Music to Hewlett-Packard

Future computer printers made by Hewlett- Packard Company will have a clear connection to the University.

That's after the world's largest maker of printers for computer use and the University agreed in December on a licensing agreement for a halftoning technology invented by Rochester researchers that helps produce better copies.

The technology, called a "blue noise mask," was invented more than a decade ago by Kevin Parker, dean of the School of Engineering and Applied Sciences, and former graduate student Theophano Mitsa, now a scientist at a Boston-based medical equipment company.

The technology is the subject of six U.S. patents and several international patents that have been issued. This year's agreement ended an eight-year legal battle over the rights to the technology.

The patents were filed on behalf of the University by Research Corporation Technologies of Tucson, Arizona, a company that helps universities commercialize technology developed in their laboratories.
