Abstract
A process for printing a two-sided visual display for attachment to a window, screen or object is provided which can be identically viewed from either side of the support surface. The carrier sheet is of the electrostatic adhesion type which clings to the support surface without glue or other adhesives. The display is formed by being printed on one side of the flexible transparent carrier sheet with quick drying inks having the final desired color. The inks are applied directly to the carrier sheet without overlap or underlayment. Each color segment can be overprinted in order to emphasize and enhance the color of the individual sections. A cover sheet can be applied to the display to facilitate handling and storage. The final product when in place can be visibly observed from either side with equal clarity and appearance.
