Abstract
Compositions for and methods of digitally printing an ink image onto a woven textile material are provided. 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.
Claims10
A method of digital inkjet printing an image onto a substrate, comprising:
- applying a base application onto at least a portion of the substrate corresponding to an area upon which the image is to be imprinted;
- printing at least one digital ink onto at least said portion, while said portion is still wet by said base application, using a inkjet printer;
- and
- curing the image, thereby forming the image, wherein:
- said applying is effected by at least one applicator;
- said printing is effected by at least one inkjet printhead;
- said digital ink and said base application being kept separate from each other until discharged toward or upon 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.
