Adobe has announced Adobe Acrobat 5.0, its revised Portable Document Format (PDF) authoring application.

Version 5.0 offers new features aimed at corporate and networked offices. It includes 128-bit password encryption to limit access to documents, and will control which actions - if any - viewers of an Adobe PDF file can take. Acrobat will also let authors prevent others from printing, repurposing or changing its contents – including comments.

Acrobat 5.0 can share content between users. PDF files can be saved as a Rich Text Format (RTF) file in order to place the text into reports and presentations. It's also possible to extract images from PDF documents and save them as TIFF, JPEG or PNG files.

Working on the Web Workgroup members can review and add comments to PDF documents from within a Web browser. Acrobat tools are built in to the browser, through which text can be highlighted, struck through and underlined. Also, documents can be digitally signed.

Version 5.0 will also build electronic forms with fields that change dynamically depending on the data inputted. A Web Capture command can convert single Web pages or sites into PDF files, preserving the URL links.

Other features include batch processing, customizable toolbars and spell checking. Adobe is tightening integration between all its applications, and Acrobat 5.0 will convert transparent objects created in Illustrator 9.0 and Photoshop 6.0 into Acrobat PDF files without losing any formatting. PDF files can also be opened and edited in Illustrator.

Acrobat 5.0 will automatically print oversize documents on multiple A4 pages. It can also rotate pages, and it supports ICC colour profiles. It will cost £205, upgrades cost £75.
