Abstract: A method of applying a heat fixable ink image to a moulded thermoplastic component involves applying an image to carrier sheet, applying the carrier sheet to the component to conform to the surface contours thereof and then heating the image to a temperature below that temperature at which the image will satisfactorily transfer to the component. A pressure of such magnitude and duration is then applied to the image through a pair of mating dies of complementary shape to the component as to then cause the image to tansfer to the component to become permanently fixed thereto.
