Abstract
Described herein is a method and apparatus for ink jet printing. The method includes providing a wetting enhancement coating on a transfer member. The wetting enhancement coating (WEC) includes water, an acid treated, waxy maize cationic starch, a humectant and a surfactant. The wetting enhancement coating is dried or semi-dried to form a film. Ink droplets are ejected onto the film to form an ink image on the film. The ink image is dried and the ink image and film are transferred to a recording medium.
