1. A method of preparing an adhesive-backed article, said method comprising:
providing a release liner having a microstructured release surface; providing a pressure-sensitive adhesive layer having a microstructured adhesive surface, with a pattern of channels being formed in the microstructured adhesive surface that define a volume of at least 1×103 μm3 per any 500 μm diameter circular area of the pattern; and laminating a compliant film to a surface of the pressure-sensitive adhesive layer that is opposite the microstructured adhesive surface, with the compliant film being solid and pigmented and having an inelastic deformation after being stretched once to 115 percent of its original length, wherein the microstructured adhesive surface is in contact and mated with the microstructured release surface, and the microstructured adhesive surface has channels that define exit pathways that can provide fluid egress to a periphery of the compliant film.
