Abstract
Methods and apparatus for in-line conditioning of swellable print media prior to printing. Treatment with an amphiphilic solvent increases the hydrophilicity of the media surface, thereby accelerating ink penetration and improving image quality in high throughput printing. In addition, ionic components in the treatment fluid can be used to accelerate precipitation of pigment or dye from the ink.
