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

摘要

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.

主权项

1. A method for transfix ink jet printing comprising:
coating a wetting enhancement coating on a transfer member, wherein the wetting enhancement coating comprises; water, a cationic starch, a humectant and a surfactant; drying the wetting enhancement coating to form a film having a thickness of from about 0.05 microns to about 5 microns; ejecting ink droplets to form an inkjet image on the film; and transferring the inkjet image and the film onto a recording medium.
