Abstract
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.
