<p num="1"><br/><br/><br/>A printing system for use in inkjet printing. The printing system comprises an <br/>inkjet ink having a free binder and a modified pigment, a fixer fluid, and a <br/>porous print medium. The free binder may include polymers selected from a <br/>polyethyleneimine, a polyguanide, a styrene maleic anhydride imide, a <br/>quaternary ammonium compound, a styrene-acrylic polymer, a styrene maleic <br/>anhydride polymer, a polyurethane, and mixtures thereof. The at least two <br/>polymers may be present at a molecular weight ratio ranging from approximately <br/>0.001 to approximately 10. A method of producing a printed image having <br/>increased resistance to wet smudge is also disclosed. The method comprises <br/>providing a porous print medium, applying an inkjet ink to the porous print <br/>medium, and applying a fixer fluid to the porous print medium.<br/> |
