Abstract
A method of accurately printing a target color is provided. The method comprises: in a first step measuring the light spectrum (106) of a first printed color sample (104), which has been printed with a first ink coverage; and from the measured light spectrum calculating a color discrepancy between the first printed color sample and the target color. The method further comprises in a second step calculating an improved ink coverage (112), and printing a second color sample with the improved ink coverage (104). The aforementioned steps are repeated until a predetermined condition for accuracy of the target color has been reached (110).
