ABSTRACT:
An apparatus and method are described for applying an intermediate transfer surface, in the form of a liquid layer, on a support surface that may be used in a phase change ink printing system. The apparatus includes an applicator assembly with a leak-free valving system for distributing the liquid layer onto the support surface to produce the intermediate transfer surface and a means for metering the liquid layer uniformly on the support surface. The applicator assembly has a wick contact surface for removing foreign matter from and delivering the liquid onto the support surface. An improved liquid dispensing system is provided to provide the liquid to the wick which becomes saturated and, when brought into contact with the rotatable support surface of a transfer drum, applies the liquid in a layer to the support surface to form a liquid intermediate transfer surface.
