  • Patent number: 6248404
    Abstract: The present invention involves a method for altering preexisting patterns of ink on paper. Used, waste paper is treated such that words, images and pictures are altered to form substantially different and aesthetically pleasing patterns. A chemical activator is applied to waste paper, thereby causing the present ink to diffuse. Optionally, additional inks may be added and further diffused across the paper. Once the treated paper has dried, a new, unique pattern has formed. In this manner, previously unuseable paper becomes suitable for a variety of aesthetic purposes. The resulting paper product may be used for wrapping paper, contact paper, wallpaper or the like.
