Abstract
High speed printing machine incorporating a pressure-sensitive transfer ribbon of the squeeze-out or reusable type having a thin, flexible plastic film foundation having bonded thereto a microporous resinous ink layer containing pressure-exudable liquid ink which is adapted to be pressure-transferred to a copy sheet by means of a printing element which makes momentary impression contact with the ribbon while the ribbon is moving slowly across the path of said printing element. The invention comprises a high speed printing or impact machine which includes means for the application of a thin friction-reducing or slip-permitting film of liquid silicone oil to the rear or impact surface of the transfer ribbon in order to reduce the friction between the printing element and the moving transfer ribbon and to prevent grabbing of the film foundation and breakdown of the bond between the film foundation and the ink layer.
