I'm looking for a way to detect thin, white text in a PDF. I have tried to make a restriction in a preflight to look only for fonts that has Thin or Light in their fontname and have white fill. Using a very simple RegEx like this ".dThin" would find ec. ProximaNova-ThinIT if I test this in a RegEx-tester, but it doesn't seem to work when used in the "select Font"_action.

Any other suggestions on how to detect thin, white text?

If anybody want to know, I have now learned (from Andrew ) that the correct RegEx should look like this:

.*Thin.*
