Abstract
A security document is provided comprising a finished cellulosic substrate having at least one transparentized portion formed therein. The transparentized portion comprises a transparentizing composition that is applied so as to define an area of increased transparency in the substrate. The area of increased transparency includes at least one thin line and resembles a simulated security thread. The transparentizing composition can be applied to form thin lines in a variety of configurations on one or both sides of the substrate.
