Abstract
Abstract A method of producing ultra removable paper products having printed matter on at least one surface thereof, comprising the steps of: printing the printed matter on the selected surface or surfaces of the paper by any conventional printing process; applying a coating of non-aqueous varnish to both surfaces of the paper; coating a relief printing plate with a resin bonded fluorocarbon; heating the plate to the curing temperature of the resin bonded fluorocarbon; transferring pressure sensitive adhesive from a suitable reservoir to the relief printing plate; and engaging one surface of the paper with the adhesive so as to transfer a coating of adhesive to the paper.
