Retrieving a Monaco Session with CP2

Restoring a Monaco session into CGATS format for PM5
Monaco session saves the colorimetric data in Lab values only, no spectral data was saved. Following procedure helps to recover the previously measured Lab values to CGATS file.

1. Open ColorPort2, go to Measure Target menu and select the appropriate target to be restored. Drag&drop the saved Monaco session data into CP2.

2. Save data in CGATS.
Do not save with PM5 option. The reason being that PM5 option saves both rgb and spectral data. The RGB data cannot be used for printer profiling.
CGATS option in CP2 saves data in RGB, Lab as well as spectral reflectance. Remember to select spectral value scale 0-100 as that is the default for PM5.
The spectral fields for both output options are null.


3. Open the saved file with a notepad editor. Delete the spectral field header, row count is optional, others untouched. Refer to the illustration for clarity.






4. Open PM5 ProfileMaker, assign the corresponding reference data and drag&drop the edited file. You are now ready to proceed to generate the icc profile.
