ABSTRACT:
The present invention is an improved printable sheet for use in a variety of applications requiring extreme image durability and weather (e.g., water) resistance. The printable sheet of the present invention employs an expanded polytetrafluoroethylene sheet comprising a series of polymeric nodes interconnected by fibrils. Images can be applied to this sheet using a variety of means, including pen and ink, electrostatic printing, screen printing, offset printing, etc. These images have proven to be very durable and capable of substantial wear, water exposure, and general abuse. Moreover, the printable sheet of the present invention is capable of being cleaned and reused over and over again once any given image is no longer of interest.
