Abstract
Brochures, pamphlets, books, and the like containing a plurality of laser-perforated paper which has been folded and bound (in either order) on the lines of perforation have, among other things, substantially improved compressed, lay-flat properties (i.e., significantly reduced bowing) as compared to conventional perforated paper containing books, pamphlets, and the like. Additionally, the inventive articles have surprisingly high strength on the lines of perforation and low paper slippage as well. The inventive processes provide for an easy and efficient way to produce brochures, pamphlets, signatures, and other paper-based products which are easy to handle, store, and transport.
