Printing Curve
The measurement function Printing Curve displays a complete transfer curve, which
describes how screen dots (and tonal values) are transferred during the several pro-
cess steps of the reproduction process.
First, make the required settings in the Print-
ing Curve Setup:
1. Tolerance range can be set according to
standard values (in this case the ISO Paper
Class 1/2 was selected)
2. Dot (screen) frequency (only relevant for
the display of tolerance values)
3. Increments of the wedge to be measured,
e. g. in 5 % steps
In the rst step a 100 %-(solid) patch is mea-
sured. SpectroDens recognizes automatically
the color and displays the solid density. In this
case D = 1.50 for Cyan.
The double arrow in the upper left corner in-
dicates that the next patch to be measured
will be a 90 %-patch. Now all other pre-set
%-patches can be measured on the measure-
ment wedge.
Step wedges with separation bars (as shown)
can be measured by scanning. Just keep the
green start-button pressed during the whole
scanning procedure.
