1. A method for the manufacture of a projective capacitive touch (PCT) panel comprising;

  • onto a transparent substrate, uniformly depositing a layer of transparent conducting material (TCM);

    onto the same transparent substrate or onto the TCM layer printing a printable conductive ink (PCI) in selected areas to form one or more coarse conducting border regions;

    ablating material in the PCI layer and the TCM layer together to form a plurality of discrete electrically conductive tracks (busbars) in said coarse conducting border regions and in the same laser ablation process ablating a pattern of electrodes into the remainder of the TCM layer.
