An apparatus (40) and method for printing a conductive grid onto a plastic panel (24), and a- resultant product. A nozzle (48) is mounted to the end of an arm (42), and the nozzle (48) is coupled to a source of conductive ink. A flow regulator (47), coupled to the ink source (49), regulates the flow rate of ink out of the nozzle and is controlled by a controler. The controller is further configured to apply an initial conductive trace onto a panel and to apply a subsequent conductive trace beside or onto the initial conductive trace to vary the volume of the grid line along a portion of its length.
