<p>Sheet binding where the printing medium itself is the sheet binder. In a xerographic process, high density areas of xerographic toner are provided at desired binding areas. Sufficiently high density toner areas are provided by inserting a finely apertured optical mask adapted to provide edge development effects to maximize overall toner density over the selected binding area, yet which is compatible with solid area coverage machines. These toner binding areas may then be subsequently re-fused between adjacent overlaying sheets to provide bound stacks, without requiring any additional binding material.</p> |
