Measurement data from a printing process always exhibit certain fluctuations and deviate from an ideally smooth colour space. The causes include, among others, the ink laydown of the printing process, the homogeneity and surface structure of the substrate, and the optics and mechanics (robotics) of the measuring devices.
The intelligent smoothing analyzes the measurement data with regard to a defined admissible level of deviation from the ideal and corrects all measurement values that exceed this level.
The admissible level of deviation from an ideal gamut is set via the Strength parameter of the Smooth function:
- a low value (e.g. 1) still allows larger deviations
- a high value (e.g. 10) largely reduces deviations and brings the data closer to an ideally smooth colour space
Repeatedly running the Smooth function with the same Strength is uncritical and will not lead to further changes once the configured level of smoothing has been reached.
Excessive smoothing can cause the measurement data to no longer accurately represent the actual printing conditions. As a result, profiles calculated from these data may not produce the desired visual outcome.
Measurement data with many or strong deviations can also indicate an unstable printing process or an unsuitable measuring device for the paper/ink combination used to print the test chart.
