Patent 8439487 was granted and assigned to Eastman Kodak on May, 2013 by the United States Patent and Trademark Office.
A method for creating composite droplets for use in an ink jet system includes a first fluid (1) brought into contact with a second fluid within a set of channels (5,14). The interface between the fluids is characterized by an interfacial tension. The first fluid forms spaced droplets (8) within the second fluid, the composite of the first and second fluids passing through an orifice (6) to form a jet (9).
