A while back I wrote about Acrobat's watermark feature. At that time, I created the watermark by typing the word DRAFT in the watermark creation dialog box.
There's another type of watermark possible in Acrobat 9--an image-based watermark that will allow you to have your company logo display on each page. The image watermark can be bold or subtle, and can appear on whatever pages you choose.
To insert an image-based watermark, choose Document > Watermark > Add.
Select File as the source and browse for your desired image file. (Accepted file formats are .pdf, .bmp, .rle, .dib and .jpg.) In my example, I selected a PDF file that I made from a coat-of-arms image. In the preview pane, you will immediately see a preview of the image and it will seem rather harsh. Not to worry. The image comes in with an opacity setting of 100% by default. For images, I like to dial the opacity percentage down to around 20%. Depending on the dimensions of your image file, you may opt to scale it to each targeted page. (In my example, I have it set to scale to 80%).
There are other options with which you may want to try such as image rotation and behind versus on top of page. By clicking the Appearance Options link, you can further tweak the watermark to show or not when the document is printed, and/or displayed on screen.
If your document has varying page sizes, you can opt to keep the watermark's position constant or not. You can even specify coordinates to place your watermark in a specific location on your pages.
If you need to apply this new custom watermark to more than your current PDF, you can click the Apply to Multiple button to select other files to include.
