PDF And You

Among the features that have been added in the 1.3 specification are tools and/or support for trapping, embedding ICC profiles, trim and bleed, spot and special colors, and the ability to embed external data streams within the PDF. However, although the specification supports all of these capabilities, the stand-alone Acrobat 4.0 application does not, as Adobe has opted to rely on third-party plug-ins for high-end output controls.
