One-way see-thru panel and method of making same

This invention describes a method to create a special sticker that allows people inside to see out, while those outside only see a printed image. It involves taking a light-colored plastic sheet, applying a dark, sticky layer to one side, and then coating the other side to accept inkjet printing. The entire assembly is then perforated with tiny holes, making it suitable for displaying graphics on windows or vehicles.

Why it matters: Since 2004, wide-format inkjet printing technology has significantly advanced in speed, resolution, and ink durability, especially for outdoor applications. Improved coating chemistries and more robust inks now allow for more vibrant and longer-lasting graphics on these panels.
