Clipping and inverting the values of an opacity mask
When you select artwork that has an opacity mask, the Clip and Invert Mask buttons
become enabled in the Transparency palette. The Clip button specifies that the mask
doubles as a clipping mask, making the masked objects fully transparent outside the
boundaries of the masking artwork. The Invert Mask command reverses the luminosity

both options to create a clipping opacity mask that uses inverted luminosity values.
