You can use the Save As command to save RGB, indexed-color, CMYK, grayscale, Bitmap-mode, Lab color, and duotone images in Photoshop PDF format. Because the Photoshop PDF document can preserve Photoshop data, such as layers, alpha channels, spot color, and annotations, you can open the document and edit the images in Photoshop CS2 or later. You can also use the Photoshop PDF format to save multiple images in a multipage document or slide show presentation.

You can quickly save a file as Photoshop PDF by playing the Save As Photoshop PDF action on the file. You can access this action by choosing Production from the Actions palette menu.

For advanced users, the Photoshop PDF format offers options for making the document PDF/X compliant, which is essential, for example, when you send your document to a large commercial press. PDF/X (Portable Document Format Exchange) is a subset of Adobe PDF that eliminates color, font, and trapping variables that lead to printing problems.

You can also specify security options for restricting access to the PDF document. The 128‑bit RC4 (Acrobat 6 and later) encryption has an option for letting users view metadata and thumbnails in a secure PDF document using Adobe Bridge.

You can save your PDF settings as a PDF preset for creating consistent Photoshop PDF files. Adobe PDF presets and settings are shared across Adobe Creative Suite components, including Photoshop, InDesign, Illustrator, GoLive, and Acrobat.

Adobe Creative Suite users can find more information about shared PDF settings for Adobe Creative Suite applications in the PDF Integration Guide on the Creative Suite CD.
