Abstract
An image is printed onto a substrate having a surface. A coating is applied to the surface which includes a reactive water dispersible species and a solvent. An image is printed onto the coated substrate using an ink jet printer which supplies aqueous ink to thereby form the image on the substrate.
Claims22
A method of printing an image with an ink jet printer, comprising:
- obtaining a substrate having a surface;
- preparing a coating mixture which includes a reactive water dispersible species, a sensitizer to increase the susceptibility of the water dispersible species to polymerization in response to an initiator, and a solvent;
- coating the surface of the substrate with the coating mixture;
- initiating polymerization of the substantially reactive water dispersible species by applying the initiator to the coating;
- placing the coated substrate into an ink jet printer following the step of initiating;
- and
- applying the image to the coated substrate using a substantially aqueous ink applied by the ink jet printer whereby the ink is absorbed into the polymerized coating such that a printed surface of the substrate is substantially dry following application of ink.

A method of coating a substrate using an ink jet printing mixture for receiving ink jet printing to form an image on the mixture when coated on a substrate, the ink jet printing mixture comprising:
- a reactive water dispersible species;
- a sensitizer to increase the susceptibility of the water dispersible species to polymerization when exposed to an initiator;
- and
- a solvent mixed to a consistency suitable for inkjet printing, the method comprising providing a substrate;
- coating the mixture coated onto the substrate, thereafter applying the initiator to cure the mixture on the substrate, the solvent causing the cured mixture to have sufficient porosity to allow the ink jet ink to penetrate the cured mixture and thereby reduce the susceptibility of the printed ink to smear.
