Wetting enhancement coating on intermediate transfer member (itm) for aqueous inkjet intermediate transfer architecture

An ink jet printer comprising:

• a transfer member;
• a wetting enhancement coating station adjacent said transfer member that provides a wetting enhancement coating on the transfer member wherein the wetting enhancement coating comprises;
• water, a cationic starch, a humectant and a surfactant;
• a drying station adjacent said transfer member for drying the wetting enhancement coating to form a film on the transfer member;
• a print head adjacent said transfer member that ejects aqueous ink droplets onto the film;
• a transfixing station located adjacent said transfer member and downstream from said print head, the transfixing station having a transfixing roll forming a transfixing nip therewith at said transfixing station;
• a transporting device for delivering a recording medium to the transfixing nip wherein the ink image and film are transferred to the recording medium.
