ULTRASONIC TRANSFER PRINTING WITH MULTI-COPY, COLOR AND LOW AUDIBLE NOISE CAPABILITY ABSTRACT OF THE DISCLOSURE A printing or copying system in which ink is transferred from an ink-bearing medium to a printing medium through the use of ultrasonics. The ink-bearing medium may be an ink ribbon, carbon paper or the like which is in contact with a printing medium such as paper. Ultra- sonic energy is applied to the ink-bearing medium through transmission fibers, wires or bundles thereof, causing the viscosity of the ink to be reduced due to the ultrasonic vibrations and conversion of the ultrasonic energy into heat such that the ink is transferred to the printing medium. Multi-copy capability is achieved by having alternate layers of carbon paper or the like in contact with the paper.
