Abstract
A method of selecting a pigment ink set and receiver in combination including: printing at least two color inks onto a set of receiver to form single color patches of a Dmax density (100% dot coverage); measuring the gloss level of each patch and the receiver at a predefined specular angle; calculating the Relative Gloss Difference (RGD%) value of the ink set and receiver combination; and selecting the ink set and receiver such that RGD value is less than 40% when 60° is used as the specular angle, and the RGD value is calculated according to Equation (A): whereI 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.
