How can I export visual density values

Hello, I have spectral values as cgats file. I would like to export a visual density values like colorport does?

If you bring your CGATS file into ColorThink Pro, it will open automatically in the Worksheet and display the Lab values. You can save the file out as Lab values. And then the Lab values can be plugged into a calculator like the Companding Calculator at Bruce Lindbloom’s site:

You would use the L* values to approximate the equivalent density. Not sure how accurate this would be in your situation, but it should provide a reasonably good relative accuracy within the same set of measurements.
