A method of making a pressure sensitive adhesive article includes depositing a layer of liquid adhesive material onto a substrate, and depositing a layer of non-adhesive liquid material onto the liquid adhesive material, wherein the non-adhesive liquid material covers only a portion of the liquid adhesive layer. The liquid layers can be cured which allows winding the article onto a spool. The pressure sensitive adhesive article includes a substrate with a liquid adhesive layer deposited onto the substrate. At least one liquid non-adhesive structure is deposited onto a portion of the liquid adhesive layer, and the structure can have a theoretical angle of contact with the adhesive layer which is greater than 0°.
