A process including: jetting at least one ink from a color ink set onto a substrate to form a first pixel; and jetting a heliosing ink onto the first pixel to form a heliosed pixel, wherein the first pixel is substantially free of resolution diminution in the heliosed pixel. The process can also be accomplished in the reverse jetting order, that is, jetting a heliosing ink onto a substrate to form a patent or latent heliosed first pixel; and jetting at least one ink from a color ink set over the heliosed first pixel to form a heliosed color pixel, wherein the resolution in the heliosed pixel is substantially the same as the resolution in the absence of the heliosing ink. The heliosing ink formulations can include, for example, one or more of: an obscurant, a bleachant, or a penetrant. The processes of the present invention can be used to create heliographic images.
