  • Publication number: 20160144634
    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.

  • Publication number: 20150252205
    Abstract: The present disclosure sets forth a fluid set and a method of wet-on-wet printing. The fluid set can comprise an analog pretreatment fluid including water, latex, and a salt; and a first and second inkjet ink each comprising water, pigment, a solvent system, and a surfactant system. The analog pretreatment fluid can be prepared to have a surface tension from 32 dynes/cm to 40 dynes/cm. The first inkjet ink can have a surface tension ranging from 2 dynes/cm greater than the surface tension of the analog fixer fluid to 6 dynes/cm less than the surface tension of the analog fixer fluid. Likewise, the second inkjet ink can have a surface tension ranging from 2 dynes/cm greater than the surface tension of the analog fixer fluid to 6 dynes/cm less than the surface tension of the analog fixer fluid.
