Spot measurement
To carry out a spot measurements just position the SpectroDrive device with the
measurement head on a single measurement patch and press the green measurement
button shortly. An acoustic signal confirms, that the measurement is completed and
the measurement data are displayed by the ExPresso software in the window "Spot
measurement" in the submenu "Sample".
All relevant density- and colorimetric-values are shown here very clearly and can
therefore be interpreted at a glance. The maximum density according to the wave
length is displayed as well.
In the menu "Spot measurement  Reference" (see p. 56) a reference can be select-
ed for the measured color. This can be a second measurement or an already defined
ink (see p. 27).
The window "Spot measurement  Deviation D" (see p. 56) displays the deviation of
the measurement values of the sample to the selected reference. The densitometric
and colorimetric numerical values are supplemented by a graph.
