    摘要: A process comprising incorporating into an ink jet printing apparatus a developing composition; an oxidizing composition a coloring composition; and a fixing composition; ejecting droplets of the developing composition onto the substrate; ejecting droplets of the oxidizing composition onto the substrate; ejecting droplets of the coloring composition onto the substrate; and ejecting droplets of the fixing composition onto the substrate; wherein the process results in at least some portions of the substrate bearing images comprising all four compositions, the portions forming a printed image. Specific embodiments are directed to the realization of continuous tone and gray scale in image by control of the time at which color forming reactions are quenched by controlling the lime period between deposition of the color forming liquids and deposition of the fixing liquid; or control of the extent of color forming reactions by limitation of the quantity of one of the color forming liquids.
