A structured paper release liner (10) for use with an article (44) backed with a pressure sensitive adhesive, an adhesive-backed article assembly (42) and methods of making each are disclosed. The liner (10) comprises a piece of paper (14) having a release side free of a structural support layer, a back side, and a structured release surface (48) having a pattern formed into the paper (14) on the release side. A release material is on the structured release surface of the paper. The pattern formed in the paper (14) is designed so as to form fluid egress channels in a bonding surface of the pressure sensitive adhesive (46). The fluid egress channels define a structured bonding surface (48) having exit pathways for fluid to bleed out from behind the article when the structured bonding surface (48) is adhered to or otherwise disposed on a substrate.
