Complete the following test so you can be sure you understand the material. Your answers are private, and test results are not scored.
The main purpose of a watermark is to:
Authenticate your document as the original.
Add a dappled, waterlike finish to your printed document.
Communicate useful information or add visual interest without overpowering the main text of the document.
A main difference between backgrounds and watermarks is:
Backgrounds are always solid colors, and watermarks are always transparent images.
Backgrounds are intended for documents that will be viewed on the Web, and watermarks are intended for printed documents or documents that will be viewed in print layout.
There is no difference. The two serve the same function.
