I know at least three ways you can put a watermark text in your documents:
- Background image
- Drawing text
- Insert Fontwork
1) Background image
Select your page style in the style navigator. Right click and choose Modify.
Select the Background tab and select Graphics in the first field.
Now you can select an image file from your system.
You can either stretch the image or place it on a specific position.
2) Drawing text
From the Toolbar Drawing, select the tool Text.
Draw a box with you mouse and type the text in the box
If you want to see the background text on all pages, you can draw the box in the page header or footer
Mark the text in the box and format it as you need (text size, font, color etc.)
If you mark the text, you can use the rotate tool to rotate the text (grab the corners with your mouse and drag)
Mark the text box and right click. Select Arrange. Select In background
Click once in the page header og footer
Click Fontwork Gallery and select a Fontwork style
Type the text you want to appear in the background
Select the inserted Fontwork, right click and select Wrap - In background
Each of the above methods has advantages and disadvantages. Choose from your needs in the individual case. There might even be other methods to achieve the same or better results.
