ABSTRACT:
A test page produced by ink pens for calibrating drop weights for at least a first and a second printheads, comprising: a page with an area for color swatches; a plurality of color swatches disposed in the area; and a predetermined substantially uniform color background disposed in said area between and around said plurality of color swatches. In a system embodiment of the present invention, a sensor may be used for sensing spectral data for each color swatch in a plurality of color swatches; and a component may be provided for comparing the sensed spectral data for each color swatch in a plurality of the color swatches to spectral data for the background color and selecting one of the plurality of color swatches which has spectral data which is closest to the background color for use in adjusting ink volume for at least one of the ink pens.
