Abstract
A process for providing circuit lines on a substrate having a non-planar surface is provided. The process includes applying a layer of photoresist material to the substrate, selectively screen printing on non-planar areas of the substrate a screen-printable coating, photoprocessing the layer of photoresist material, and providing electrical conductive pattern on the substrate.
