Cadmus Communications Corporation announced the release of a Macintosh client for its RapidRights digital rights management (DRM) software. The Mac client will run on Mac OS X v10.3 or higher and will use Preview, the built-in Mac Viewer for PDF. RapidRights allows publishers to deliver protected PDF files and is a DRM solution that does not require a separate download or plug-in to open the protected files. RapidRights is the electronic delivery component of Cadmus’ ArticleWorks, a comprehensive content delivery and digital rights management system with complete e-commerce functionality that enables publishers and other content providers to deliver content on demand in either printed or secure electronic formats.
