摘要： 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.

摘要： A method of producing a print medium to reduce problems associated with the gradual dye-fade and color-shift of inks over time, and to provide improved resistance to physical handling is provided Specifically, a method can comprise steps of coating a media substrate with a porous coating composition of semi-metal oxide or metal oxide particulates to form a porous ink receiving layer, coating the porous ink-receiving layer with a latex layer configured to allow an ink-jet ink to be received at the porous ink-receiving layer, printing ink-jet ink on at least a portion of the latex layer to form ink-associated latex regions exclusive of non-printed latex regions, and heating the latex layer. The ink-jet ink can include an ink vehicle, a colorant, and a film promoting additive that lowers the film forming temperature of the latex particulates in the ink-associated latex regions. Upon heating, the ink-associated latex regions form a continuous film, and non-printed latex regions do not form a continuous film. Associated systems and ink-jet prints are also provided.

摘要： The present invention relates to a print medium with improved resistance to airfade. The print medium is coated with a high molecular weight additive having low volatility. The high molecular weight additive is a monomeric or oligomeric compound that has a molecular weight of greater than approximately 1000. The high molecular weight additive is a hindered amine light stabilizer or a fixative. The present invention also relates to a method of producing a print medium with improved airfastness. The method comprises coating a print medium with a high molecular weight additive having low volatility. An image is then printed on the coated print medium and subjected to at least one atmospheric gas. The airfastness of the printed image is measured and compared to the airfastness of an image printed on an uncoated print medium.

摘要： A process is provided that allows the production of an ink-jet recording media by applying a sealable topcoat to an ink-receptive coating on a substrate. A porous ink-receptive coating comprising a plurality of pores is applied to a surface of the substrate. An anionic porous topcoat comprising polymer particles having a Tg in the range of 60° to 100° C. and a size less than 250 nanometers is applied on the porous ink-receptive coating. The topcoat is then dried at an elevated temperature and an image is printed on the topcoat of the ink-jet recording media using a conventional ink-jet printer. The topcoat is then heated until it becomes fused by using a heating device. The media formed provides the advantages of improved air fade resistance, good image quality and high gloss.
