1. A multi-film thermoplastic structure comprising:
a first thermoplastic film having a first appearance;
a second thermoplastic film having a second appearance created by a pigment, the first appearance differing from the second appearance;
one or more separated portions where the first thermoplastic film and the second thermoplastic film are not in intimate contact; and
one or more contact areas arranged into text, wherein the one or more contact areas arranged into text comprise:
portions of the multi-film thermoplastic structure where the first thermoplastic film and the second thermoplastic film are in intimate contact; and
a contrast relative to separated portions surrounding the one or more contact areas, which when viewed in the first thermoplastic film makes the text legible, wherein the contrast is due to a difference in Delta E of 5 to 15 points between the one or more contact areas arranged into text and the separated portions surrounding the one or more contact areas.
