You can mask those parts of the page content that you do not want to print. For example, you want to remove a company logo from a document. Applied masks will be scaled, rotated and shifted along with the content of the pages.
NOTE
Any mask that you apply on page content disappears when you click the [Clean-up] button. After you close the [Clean-up] dialogue the mask appears again. For example, you have masked some page content. Then you click the [Clean-up] button. This causes the mask to disappear. In the [Clean-up] dialogue you align the content of the page. Then you close the [Clean-up] dialogue and the mask appears again. Now, the mask might cover some of the aligned page content. Therefore, always do a clean-up before you mask any content.
Select the pages for which you want to mask a part of the page content.
To select a page range: select a page in the structure view, press the <Shift> key, then select another page.
To select non-sequential pages: select a page in the structure view, press the <Ctrl> key, then select several non-sequential pages.
Click [Pages] - [Mask].
Use any of the selection tools to select the area that you want to mask.
Click [Apply].
