Abstract
A first mist having at least one material is selectively applied to selected portions of a recording surface to form desired characters or other information thereon. A second mist of a material which reacts with the one material is applied to the recording surface. The reaction of the two materials forms a compound on the selected portions of the recording surface having a sufficient contrast with the recording surface to produce characters or other information on the recording surface. If the one material has an ink applied therewith to the recording surface, the material in the second mist reacts with the one material to enhance the contrast of the ink on the recording surface.
