ABSTRACT:
A process for printing in which a layer of ink on an ink transfer pad is cured at the interface between the ink layer and the pad and left substantially uncured at the outer surface to provide a tacky surface for contact of the ink layer with a printable substrate. The partially cured ink layer is thus easily transferred from the ink transfer pad to the printable substrate by bringing the tacky surface into contact with the substrate. Inks which contain an oxygen-inhibited resin such as acrylates and unsaturated polyesters, and which are treated with long wavelength ultraviolet light, selectively cure at the interface of the ink layer and the transfer pad.
