Place objects in the background
You can add text, watermarks, logos, or other images that appear in the same place in the background of every page of your document. These repeated elements are called master objects.
If your document is divided into sections, you can add different master objects to each section.
Add a master object
Add an object, text, or image to any page in the section, then drag it where you want it to appear on each page.
To add an image, click Media first.
With the object still selected, use the Opacity slider in the Style pane of the Format inspector to change the object’s transparency.
The more transparent you make the object, the more it fades into the background behind the document content.
Choose Arrange > Section Masters > Move Object to Section Master (from the Arrange menu at the top of your computer screen).
The object is moved to the background of every page in the section.
Master objects are locked (made unselectable), by default.
Unlock a master object
To edit or delete master objects, make them selectable.
Choose Arrange > Section Masters > Make Master Objects Selectable (from the Arrange menu at the top of your computer screen).
When you’re finished editing, deselect Make Master Objects Selectable so master objects can’t be moved or deleted by accident.
