The invention relates to a method of providing two distinct photoimageable film compositions, in particular, two distinct dry film compositions, on a substrate. Each of the two photoimageable film compositions is selected to have a different developing speed and/or curing speed so that, after development, the top layer of photoimageable film overhangs the bottom layer of photoimageable film. A metal layer is subsequently deposited over the surface of the substrate. The overhang allows for the clean removal of the photoimageable film layers, without damage to the subsequently applied metal layer, because the overhang prevents the metal layer from making intimate contact with the photoimageable film layers along the interface of the substrate with the photoimageable film layers.
