A touch screen assembly for contact input systems, with the touch screen including a base substrate with an electrically resistive coating thereon. An array of reticulated spaced raised projections are formed on the inner surface, with the raised projections consisting of a developed/cured photoresist. In its formation, the photoresist is applied as an adherent layer with a release-film backing, with the layer being applied onto a heated substrate. Thereafter, a laminate is formed by passing the photoresist layer beneath a heated pneumatically actuated nip roll to cause the photoresist layer to flow, thereby forming a layer of uniform thickness. Thereafter, the laminate is masked, exposed to incident radiation, and developed so as to provide a reticulated pattern of adherent raised projections. A flexible plastic film having a resistive coating thereon is thereafter mounted on the substrate in superimposed relationship to the raised projections.
