Patent ID: 7708368

Claim:
A method for evaluating color mixing between dots of two different colors discharged onto a recording medium, the method comprising the steps of: outputting a color mixing evaluation print having a color mixing evaluation patch formed on a recording medium by dots of two different colors in such a manner that at least a portion of the dots are adjacent or overlapping; measuring a density of the color mixing evaluation patch of the outputted color mixing evaluation print; and evaluating color mixing of the dots of two colors, according to density profiles for the dots of two colors forming the color mixing evaluation patch, as obtained by the density measuring step; wherein the color mixing between the dots of two colors is evaluated according to at least one of an average value and a standard deviation of a distance between points which are prescribed threshold values for each color in a plurality of density profiles relating to the dots of two colors forming the color mixing evaluation patch, as obtained by measuring the density of the color mixing evaluation patch at a plurality of locations.
