Abstract: A desired image based on digital data is printed on a substrate. A subset of the digital data relating to a portion of the desired image is identified, wherein pixels associated with the digital data are of a predetermined spatial relationship with pixels intended to be of a different color as the pixels associated with the digital data. The subset of digital data is caused to activate a printhead adapted to emit ink of a first type. Data not of the subset of digital data is caused to activate a printhead adapted to emit ink of a second type, the ink of the first type being adapted to dry at a faster rate than the ink of the second type.

Abstract: Taggants are incorporated into marking materials used to create images. Reproduction systems detect the taggants, and use the resulting information to control reproduction. The invention is particularly applicable to color correction, enhancement and translation; document identification; image preservation and highlighting; and document control and security.

Abstract: A process for the continuous preparation of an encapsulated toner comprised of a core comprised of polymer and pigment encapsulated within a polymer shell, which process comprises continuously separately feeding an oil phase containing core monomers, oil soluble shell monomers and pigment and an aqueous phase containing surfactant into a continuous flowthrough mixing tank; homogenizing the aforementioned two phases to enable small oil droplets with an average diameter of from between about 3 to about 25 microns; overflowing the resulting droplets to at least one continuously stirred tank reactor while simultaneously feeding water soluble shell monomer to said stirred reactor to effect interfacial polymerization thereby causing shell formation; and thereafter allowing the encapsulated droplets to flow into a reactor or reactors and heating the reactor or reactors to effect free radical polymerization of the core monomers, followed by cooling, and isolating the said encapsulated toner.

Abstract: An improved process for the preparation of encapsulated toner compositions which comprises mixing in the absence of solvent a core monomer, an initiator, pigment particles, a first shell monomer, stabilizer, and water; thereafter adding a second shell monomer thereby enabling an interfacial polymerization reaction between the first, and second shell monomers; and subsequently affecting a free radical polymerization of the core monomer.
