Abstract: A method for producing flexible conductive printed circuit with a printed overcoat is disclosed. For example, the method includes forming conductive printed circuit lines on a flexible substrate, detecting locations on the flexible substrate where the conductive printed circuit lines are formed, and printing an overcoat over the conductive printed circuit lines at the locations that are detected on the flexible substrate, wherein the overcoat comprises a mixture of thermoplastic polyurethane (TPU) and a solvent having a viscosity of 1 centipoise to 2,000 centipoise to allow the mixture to be printed.
