Density
As shown in the above graph, the measurement values need only to nearly form a straight line
from the minimum density to the maximum density.
The important point here is that the measurement values make a straight line and a maximum
density corresponding to the settings is output.
If the measurement values deviate too far from the straight line and a maximum density
corresponding to the settings is not output, printer and monitor output linearity settings,
calibration, and other adjustments are necessary.
* The above graph is an example of measurements when the maximum density is set to 3.2 D
and the printed film is measured with a densitometer. Refer to the data below when the
maximum density is set to 3.1 D, or when gradation analysis software is used to take
measurements on the monitor.
* The LINEAR output cannot be set for some printer models.
In this case, try to select an output setting as close as possible to LINEAR.

Possible causes of non-linearity in measurement values:
* Inadequate calibration of printer and high-definition monitor
* Inadequate settings for CXDI printer parameters
* Faults in printer or high-definition monitor
