High-Gloss and Wide Color Gamut Pigmented Inks for Ink-Jet Printing
  DOI :  10.2352/ISSN.2169-4451.2003.19.1.art00057_1  Published OnlineJanuary 2003

To obtain ink-jet prints that exhibit both high gloss and a wide color gamut using pigmented inks, a new type of pigmented ink set was developed. The four technical features described below distinguish the new ink set.(1) The pigment, with an improved capsulation resin, easily wets and spreads on the surface of micro porous media.(2) All ink colors have a low concentration of pigment, not more than 3 wt%.(3) Special colors—red and blue—were used to enable the reproduction of print images with a small amount of pigment.(4) An optimized deposition method was used to deposit a clear ink containing a transparent resin on low print duty areas (including areas where no ink is deposited) so as to obtain uniform resin coverage across the entire print image.This ink set achieves high gloss and a wide color gamut on EPSON Premium Glossy Photo paper by(1) Depositing the thinnest possible layer of pigment; and by(2) Making as uniform as possible the amount of resin coating on the printed image.
