Abstract
Abstract A shielded multiconductor flexible cable for protection against EMI and/or RFI is disclosed. The shielded cable is comprised of a plurality of conductors disposed between two layers of insulating substrates, said cable having a graphic shield disposed on the exterior surface of at least one of the insulating substrate layers. The graphic shield is comprised of solidified conductive ink. Said ink provides an interference shield against EMI and RFI.
