ABSTRACT:
A method of predicting colors resulting from using one ink on a printer. The method includes the steps of:producing a test page for the printer, the test page having a plurality of sample ink patches, each patch having a plurality of ink dots according to a predetermined ratio for each patch, the predetermined ratios being based on a number of dots printed for a corresponding patch compared to a maximum number of dots;measuring each of the sample ink patches to produce a plurality of color space coordinates for each patch; andfitting values representing a number of dots for each patch and color space coordinates to a plurality of predetermined functions using a minimization process in order to predict the colors.
