Portfolio allows you to embed a Digmarc watermark directly into an item’s source file using the Embed Digimarc ID command. You must be registered with Digimarc to be able to embed watermarks. Watermarks are permanent data stored in the item source file.
Tip: Digimarc is a
proprietary system for adding watermarks to image files. To embed
Digimarc watermarks using Portfolio, you will need to have a Digimarc
Creator ID. For more information or to
obtain a Creator ID, visit the Digimarc website at 
http://www.digimarc.com.
Portfolio can only embed watermarks in JPEG and certain kind of TIFF files. Portfolio does not embed watermarks in other file formats, in 16-bit or multichannel TIFF files, including CMYK images and grayscale images with alpha channels.
To embed a Digimarc watermark: In the active Gallery, select the item(s) that you wish to have watermarked. From the Item menu, choose Embed Digimarc ID (Item > Embed Digimarc ID). Enter your Creator ID and choose the data that you want to embed in the file. Click “Embed” to complete the process. Portfolio will add the specified data to the selected item(s) source file.
WARNING: Watermark data is permanent and cannot be removed. If you are concerned about embedding watermarks in your files, we suggest making a backup copy of the source file prior to watermarking.
