Activate the option "Search automatically" in
the reference menu. Then the measurement
function InkCheck (ColorGuide) displays the
spot color of the color book which is closest
to the measured color.
First, a calibration on paper white has to be
made. Position the device on the paper white
and confirm the request to measure the
paper white by pressing the green measure-
ment button.
Now the device is ready for measurements
on solid color patches. In this case a yellow
patch was measured.
Density trend: It is recommended to in-
crease the density by 0.11.
Color deviation: The color distance to the
reference is 4,8 ∆E*. After following the den-
sity trend it can be as low as approx. 0,9 ∆E*.
A closer color match will be limited because
the paper and ink characteristics do not al-
low to get closer to the reference standard.
Please note that the density values are ob-
tained without the polarizing filter activated
and therefore are lower as values obtained
with polarizing filter. Please ensure that the
right measurement conditions are set.
