[QUOTED FROM iCPlate2 Manual]
The iCPlate2 is equipped with a video camera, which measures the
geometrical dot size, relevant for plate readings. For prints, the
densitometric dot size needs to be measured, as this measurement
corresponds to the visual impression. Therefore, the iCPlate2 is
not the ideal device for measurements of the dot area on paper.
Nevertheless, it can be used for visual dot analysis of prints.
