ABSTRACT:
A system and method for automatically establishing the position of a printed sample relative to a densitometer. The sample is placed on a measurement table. A target incorporated with the sample causes a step change in the densitometer output signal when the target is scanned by the densitometer. By analyzing the step change, the location of the target relative to the measurement table is determined. The location of all points on the sample are known relative to the target, thus the location of all points on the sample relative to the measurement table can be determined.
