In "Measurement settings" the fundamental settings for density- (1.) and colorimetric-
measurements (2.) are displayed.
The standard pre-settings for density measurement are
• for Europe: polarization filter on, white reference is paper white, density filter is
ISO E,
• for the USA: no polarization filter, white reference is absolute white, density filter is
status T.
You can use the "Density adjustment / Slope calibration" (3.) function, to adjust the
measurement device to the density measurement data of other devices.
• Select the window "Density adjustment / Slope calibration" and follow the instructions.
First you have to carry out a paper white calibration on the paper patch of a calibration chart
(which is optionally available). Then the reference values of the calibration chart have to be en-
tered into the text boxes of the process colors. Now the color patches (CMYK) of the calibra-
tion chart have to be measured. A green checkmark confirms that the measurement was carried
out successfully. The new density adjustment is saved with "OK". If the procedure is cancelled or
the "Reset slope values" function activated, the device will be reset into its factory-made state.
The pre-settings for colorimetric measurements are: polarization filter off, white ref-
erence is absolute white, illuminant is D50, observer is 2° and DE formula is CIELAB.
