Title: Microfluidic printing with gel-forming inks

Abstract: A method for microfluidic printing comprising pumping and mixing coloredinks which comprise a mixture of colorants, fluids, and gel-forming orgel-initiating ingredients to form ink pixels and to transfer such inkpixels to a receiver transferring position; and transferring the inkpixels to a reflective receiver which contains gel-forming orgel-initiating ingredients so that the ingredients in the transferred inkpixels and in the receiver react to form a gel and the viscosity of thetransferred ink rapidly increases to limit the flow of ink pixels wherebysuch ink pixels are fixed to the receiver and overprinting of colors isminimized.
