PSCS5 -You can easily layout a single image or a grid of thumbnails using Bridge. Select the Output workspace from the Workspace Switcher (in the upper right of Bridge CS5 ) to display the contents of the Output panel. In Bridge CS5 not only can you save these page layouts as templates to be easily reloaded at different times, but also add a custom watermark to each image. Recently, I have been doing all of my multi-image and multi-page layouts in Lightroom, but this is a great new feature for those staying within the Bridge and Photoshop workflow.

So how do you print the contact sheet from Bridge? Save & reopen in another program(Acrobat)? (Mac OS 10.6 64bit)
The easiest way would be to open the PDF file in the Adobe Reader and print from there. http://bit.ly/c3bHfU
I would like to use the watermark to add a overlay to check alignment of my images useing a 4 x 5 contact sheet (PDF). I am having trouble get overlay in the correct position. any hints?

oh… thanks!
SO, if I want to have a watermark on the entire page, not on the little images, can I do that in Lightroom, or does it have to be added as an image watermark in Bridge?
You might want to look into using an identity plate. I think this post might help:
