To set stamp properties
Click the 
Hand tool and right-click a stamp in the Document window for a shortcut menu with the following commands: Reply, Delete, Properties and Set Appearance as Default Properties. Properties lets you change the stamp’s author and subject, the opacity (transparency) of a given color, or view its revision history; choose Protected to prevent further changes to the stamp. To make a stamp blend in better with the page background, click Display, choose a color close to that of the page background and set an opacity level for it.
