Method of selecting ink jet inks in a color set
A method of selecting inks within an inkjet ink set for color printing includes: a) providing at least two color inks, each ink having a carrier and a pigment; b) printing the above inks onto a receiver using test images consisting of single color patches of a Dmax density (100% dot coverage); c) measuring the gloss level of each patch at a predefined specular angle; d) calculating the Relative Gloss Variability (RGV) values of the ink set based on the definition in Equation A; and e) selecting inks for the color set such that the Relative Gloss Variability (RGV) among inks is less than 10% when 60&deg; is used as the specular angle: 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.
