Abstract

An auto-tracking spectrophotometer has a moveable look-ahead sensor for scanning at least a portion of a color matrix. The look-ahead sensor finds a portion of the color matrix for measurement by an optical system. The optical system for measuring the color matrix is then guided using the information provided by the look-ahead sensor.
