Question 1: What are the main types of watermark?

There are two main types of watermarks:

Visible Watermarks: These watermarks are meant to be seen and are typically added to a document to ensure that the document is not copied or used without permission. Such watermarks can be text or image-based.

Invisible Watermarks: These watermarks are not meant to be seen and are used for identification purposes. They are embedded in the document and can only be detected using specialized software. Invisible watermarks can be used to track the owner of the document, monitor document usage, or to verify document authenticity. These types of watermarks are usually used in sensitive documents such as legal documents, government documents, and other confidential materials.

Question 2: How to Properly Add a Watermark?

1. Choose the right type of watermark – visible or invisible – depending on the intended use of the document.

2. Use high-quality images or text – Ensure that the watermark is clear and legible, and does not obscure the content of the document.

3. Use appropriate font and size – The font and size of the watermark should be easy to read and not too distracting.

4. Choose the right position – The watermark should be placed in a position that does not interfere with the readability of the document. Usually, it is centered vertically and horizontally, or diagonally across the document.

5. Adjust the opacity – The opacity of the watermark should be set so that it is visible but not too distracting, typically between 30-50%.

Note: Before applying the watermark, it is advisable to test it by printing or viewing it on different devices to ensure that it is visible and does not affect the readability of the document.
