Deliver scanned content faster over the Internet and fit up to six times more content on a single CD with the Compression PDF Agent, which compresses Adobe PDF Image and Searchable Image documents three to six times smaller than the original format, including TIFF. This powerful technology uses JBIG2, symbol-based compression on black-and-white (bitonal) images of text and lets you choose between lossy or lossless versions. Adobe PDF files created with the Compression PDF Agent are Web-optimized to enable documents to be streamed to the viewer, a page at a time. This eliminates the need to download the entire document before viewing.

Adobe PDF Forms Access is an automatic and interactive tagging tool that significantly reduces the amount of time it takes to produce an Adobe PDF form that can be accessed by users with disabilities, such as low vision or blindness. With Adobe PDF Forms Access, any Adobe PDF form can be turned into a tagged Adobe PDF form, which identifies the underlying page structure and reading order so people can use assistive technologies such as screen readers to understand and complete Adobe PDF forms. Adobe PDF Forms Access can help government agencies comply with accessibility mandates like Section 508 of the U.S. Rehabilitation Act. Software included in the Agent Pack includes both an Acrobat Capture agent to support automated workflows, and as a standalone utility capable of running on any desktop, even on desktops where Acrobat Capture is not installed.
Additional tools include:
The Tag Adobe PDF Agent, a second accessibility-related utility, provides a process for automatically tagging high volumes of legacy Adobe PDF files with information on a document's underlying page structure and organization. Screen readers can more accurately dictate a tagged Adobe PDF file because columns and images can be properly identified. Additionally, tagged Adobe PDF columns, documents, and files offer an easier reading experience on mobile devices because content automatically reflows to fit the width of the smaller handheld screens. Adobe offers free Adobe Reader® products for accessing Adobe PDF files on the Palm OS®, Pocket PC, and Symbian OS platforms.
The Security Agent enables you to apply a common set of security features to all documents in one automated job, eliminating the need to first scan and process in Acrobat Capture, and then process again in Acrobat 5.0. From within an Acrobat Capture dialog box, the same passwords and privileges can be set for every document in the batch.

The How to Create Accessible Adobe PDF Files booklet contains information on how to use the Tag Adobe PDF Agent within Acrobat Capture 3.0. It also covers known limitations and issues with automated tagging of Adobe PDF.
