Label assemblies are produced which obscure confidential information that is part of each label assembly, while allowing ready exposure of the confidential information in a tamperproof manner. A web of label components having a face ply with a top surface, underlying pseudo adhesion layers, an underlying image ply, an underlying adhesive layer, and a bottom release paper carrier ply are acted upon to non-impact print a security pantograph and readable indicia on the web face ply, and with an impact element generate a confidential information image on the image ply, which image is not visible from the face ply. Labels are die cut out of the web and matrix material formed by die cutting is removed so that the web then includes a bottom release paper carrier ply with a plurality of spaced labels, each having a confidential information image. The labels may be applied to a mailer or other substrate. A plurality of slits and/or perforations are formed in the face ply and one pseudo adhesion layer, including through the readable indicia, to facilitate the tamperproof functionality of the labels, the security slits and perforations typically including a plurality of generally L-shaped slits, at least one longitudinal slit, at least one longitudinal perforation, and a diagonal slit forming a triangularly shaped portion of the face ply having printing of a distinctly different color than the security pantograph. |
