Inkjet photo glossy paper with a resin-coated paper support is now a main medium for photographic inkjet printing because of its whiteness and smooth surface, which closely resembles those of the conventional AgX photo print.Inkjet photo glossy paper has two types; polymer type and porous type. Recently, porous type is becoming a major medium for photographic inkjet printing in the aspect of ink absorbing rate. But it was difficult to be compatible with high glossiness, high Dmax and ink absorbing rate.In this report, we describe below two techniques developed to achieve high glossiness and high Dmax (wide color gamut) of porous type inkjet paper.1. A new definition of glossiness of inkjet paper correlated with visual gloss evaluation.2. A way to improve density of Dmax
