A base application is applied to the surface of a woven textile material, especially one comprising synthetic resin fibers prior to application of an ink image layer. The base application comprises an acrylic latex material that is formulated to be printed on with a digital ink while still wet, thereby eliminating the need for an intermediate drying cycle in between base application deposit and printing of the ink image. ## Claims ### Claim 1 A digital inkjet printing system for digitally printing an image onto a substrate, comprising at least one inkjet printhead for applying a digital ink, and at least one applicator for applying a base application, said digital ink and said base application being kept separate from each other until discharged toward or upon a receiving surface of the substrate, wherein said base application comprises: between about 30% to about 70% by weight of an aqueous acrylic latex material; between about 2.5% to about 20% by weight of one or more acrylic resin dispersions; between about 5% to about 20% by weight of one or more coalescing agents; and between about 0 to about 40% by weight of a pigment dispersion, said one or more acrylic resins are separate from said latex material, and said acrylic latex material is characterized by a minimum film-forming temperature that ranges from −10° C. to 50° C. ### Claim 2 (depends on 1) The system of claim 1, wherein said applicator is digitally controlled to deposit said base application on said receiving surface in an area that corresponds with an area of the image. ### Claim 3 (depends on 2) The system of claim 2, wherein said applicator is a spray nozzle or an inkjet printhead. ### Claim 4 (depends on 2) The system of claim 2, wherein said applicator is an inkjet printhead and said base application is characterized by a viscosity at 25° C. that ranges 8-60 centipoise. ### Claim 5 (depends on 3) The system of claim 3, said at least one applicator is operable to generate a spray of said base application therefrom and said at least one inkjet printhead is operable to generate a spray of said digital ink therefrom. ### Claim 6 (depends on 5) The system of claim 5, wherein a spray pattern from said at least one applicator overlapping a spray patted from said at least one inkjet printhead. ### Claim 7 (depends on 5) The system of claim 5, wherein said at least one applicator and said at least one inkjet printhead are operable to generate converging droplets of said base application and said digital ink, respectively. ### Claim 8 (depends on 5) The system of claim 5, configured such that droplets of said digital ink and droplets of said base application converge and contact each other prior to said droplets contacting said substrate. ### Claim 9 (depends on 7) The system of claim 7, configured such that droplets of said digital ink and droplets of said base application converge and contact each other subsequent to said droplets contacting said substrate. ### Claim 10 (depends on 1) The system of claim 1, comprising a plurality of inkjet printheads arranged in series. ### Claim 11 (depends on 1) The system of claim 1, further comprising a drying apparatus configured to expose the image on the substrate to temperatures in excess of 100° C. for a period of at least 1 minute.
