Abstract
An undersurface imprintable label construction includes at least a translucent film having a layer of adhesive applied to a portion of its undersurface. One or more non-adhesive indicia-receiving zone(s) are on the undersurface of the film to form translucent window(s) on the film. A pressure-sensitive adhesive layer surrounds the window(s) and is releasably secured to a release liner which contains an indicia-transferring layer, such as a reverse carbon paper sheet, facing the undersurface of the film window(s). The undersurface of the film window area being disposed adjacent the indicia-transferring layer in the release liner allows visual indicia to be transferred from the indicia-transferring layer and imprinted on the undersurface of the window area(s) in response to pressure impact being applied to the upper surface of the film window area(s). The undersurface of the film may be partially masked to make the label substantially tamperproof.
