| Method for Forming Same Image Bearing Substrate Having Increased Density |
|
Overview Xerographic printers cannot print on thin paper, and as a result bound books are nearly twice as thick as those printed using offset. Retired Xerox innovator William A. Sullivan has solved this problem by a solution he calls variable caliper paper. Paper with the same I-beam strength and thickness as 20 pound bond goes through the machine for imaging, and then is squashed by post process calendar rollers, either in line or off-line. The result is a bound book half the thickness, with paper that lies flat vs. sticking up in the air. A patent for the process has been allowed by the US PTO, and is pending in Europe. Additional patents are pending. This technology was featured at a recent graphics arts conference. Copies of the slide presentations describing the technology and its benefits are also available for your perusal.
