ABSTRACT:
A multi-color ink-jet printing system includes a printing element for applying a precisely metered quantity of a colorless precursor in a binary or ternary chemical reaction to a precisely defined printing location on a recording medium surface. The precursor conditions the medium surface prior to application of one or more colorants to the recording medium surface to prevent recording medium cockle and curl, and to reduce dry time, while conditioning the recording medium surface for uniform dot gain independent of media composition. The precursor also immobilizes the colorants on the recording medium surface to enable one-pass, multi-color printing, while eliminating color bleed.
