Gradations with <unknown> tag in their name

After a characterization's gradation curve had been edited and saved separately in the database, its name did not refer to the source characterization, but instead contained the label <unknown>.

16256, 36930, 37617, 37780

High latency for characterization search

The search for characterizations in the Select Characterization dialog took very long. The dialog can be found under Projects > Favorites > [Project Name] > Edit Icon > Tools & Actions > Characterizations > From Database....

16705, 37143, 36442

Unspecific error message on CxF file import

Importing spot color data as CxF failed with an error message, not specifying the reason for the failure. We have improved the message text to show the cause. In the mentioned case, the import failed because the CxF file contained unsupported object types.

The selected file format cannot be used.

The selected file [NAME].cxf is not a valid measurement data file.

16139, 37784

Separation profiles - Wrong measuring condition with option "From Press Condition"

After a new target color space had been calculated with the option From Press Condition, its measurement condition was M0, although the source characterization's measurement condition was M1.

36847, 36882

Missing test chart reference in measurement data dialog

After a characterization had been duplicated, the reference to the test chart was missing in its measurement data dialog. Instead, a red exclamation mark was displayed as a warning signal in the corresponding selection field.

13977

Misleading error message after color specification for CxF file import

Choosing a certain color specification on CxF file import failed with an error message, saying the file would not be a valid measuring data file. This was misleading since the issue was not the CxF file but only the chosen color specification. Since it had no inks connected, it should not have appeared in the list of selectable measurements.

The selected file is not a valid measurement data file.

Unpublished projects after automatic profile removing
