ABSTRACT OF THE DISCLOSURE A colorimeter provides compensation for changes in the color signature of an object due to lamp aging. A current measuring circuit measures current to the lamp during an initial training of the colorimeter and stores a value IT indicative of the lamp current at training. When an object is scanned by the colorimeter, lamp current is again sensed and assigned a value IS. Comparison between a sensed color signature and a stored color signature then occurs. Compensation is accomplished by modifying one of the two signatures by a ratio including IS and IT.
