Abstract: UV-LED ink composition compositions containing a matrix or binder system, one or more colorants, and one or more photo-initiators. In some embodiments, the matrix or binder system is cured using one or more UV-LED sources. In some embodiments, the matrix or binder system contains one or more materials that are polymerized, crosslinked, and/or cured upon exposure to the UV-LED source. This allows the ink composition to be free of any organic solvents. After polymerization and/or crosslinking, the ink is dry. UV-LED ink compositions can be better suited for curing black inks, improve/increase productivity due to its instant on/instant off capability, and produce little or no heat. Such compositions may have environmental benefits as well as the curing process does not produce ozone and requires less exhaust air surrounding the press.

Abstract: A printing system includes a media transport device to move a medium at a speed ranging from about 15.24 mpm to about 609.6 mpm. The system includes an ink applicator to apply ink on the medium, and a treatment applicator to apply a treatment composition (including liquid vehicle, polyvalent metal salt fixing agent, and latex resin having an acid number less than 20) before or after the ink is applied, to form a printed-on medium. The system further includes a heating system programmed to: i) dry the printed-on medium at a predetermined temperature for a reduced dwell time (from about 1 second to about 40 seconds); and ii) leave residual moisture in the printed-on medium for a predetermined time after the reduced dwell time. The residual moisture is at a level that is higher than an initial moisture content of the medium prior to treatment composition and ink application.
