摘要： A method for microfluidic printing comprising pumping and mixing colored inks which comprise a mixture of colorants, fluids, and gel-forming or gel-initiating ingredients to form ink pixels and to transfer such ink pixels to a receiver transferring position; and transferring the ink pixels to a reflective receiver which contains gel-forming or gel-initiating ingredients so that the ingredients in the transferred ink pixels and in the receiver react to form a gel and the viscosity of the transferred ink rapidly increases to limit the flow of ink pixels whereby such ink pixels are fixed to the receiver and overprinting of colors is minimized.

摘要： An ink jet print head is provided that includes a nozzle plate having an outer metal layer having nozzles for ejecting ink drops, and a coating of a non-wetting polymer chemically bound over the outer surface of the metal layer of the plate. Preferably, the polymer is a block polymer having a head that includes the chemical group that chemically bonds with the outer metal layer, and a tail that is hydrophobic. The resulting polymer coating prevents inks from pooling, drying, and creating deposits which would otherwise impede or clog the ink jet nozzles. The chemical bonding between the non-wettable polymer and the metal surface creates a highly durable polymeric layer that resists being wiped off during both printing and head cleaning operations.
