Abstract
An ink jet ink set and recording element combination including A) a porous ink jet recording element having a 60° specular gloss of at least about 5; and B) a pigment based inkjet ink set including at least two inks; wherein the RGD value is less than 40% when 60° is used as the specular angle and the RGD value is calculated according to Equation (A): RGD % = ∑ I = 1 N [LeftBracketingBar] Gloss ( Imaged Areas ) I - Gloss ( Non Imaged Areas ) [RightBracketingBar] ∑ I = 1 N Gloss ( Imaged Areas ) I Equation (A) Where I is a variable which identifies a certain color patch used in the evaluation, N is the total number of color patches used in the evaluation.
