CHAPTER 2
– Measurement functions
In order to take correct measurements an ab-
solute white calibration must be performed
and will be confirmed in the display when
done.
A measurement of the paper white is neces-
sary for correct calculations.
Now the instrument is ready to measure. The
selected paper type and backing are indicat-
ed in the display.
When measuring solid inks the values are
compared to the ISO reference values. The
∆E*-value is indicated and the symbol shows
if the value is within or out of tolerance.
The recognized color and L*a*b*-value of the
measurement are displayed as well.
The selected paper type is always indicated.
