ISO 16612-2:2010 defines the PDF/VT document format and methods to enable reliable document exchange for variable data and transactional (VT) printing. It uses the Portable Document Format (PDF) Version 1.6, as restricted by PDF/X-4 and PDF/X-5, for the representation of such documents. It allows the specification of document structure and layout, content data, and interaction of graphical objects in a graphics model that supports transparency and both device-dependent and device-independent colour spaces. All elements either are included or provision is made for unique identification of externally supplied graphical content or ICC profiles.

PDF/VT is designed to enable variable data and transactional printing in a variety of environments from desktop printers to digital production presses. This includes hybrid workflows involving both conventional and digital printing.

ISO 16612-2:2010 does not provide for the specification and encoding of production and device control information but is constructed to enable its use with the International Cooperation for the Integration of Processes in Prepress, Press, and Postpress Organization (CIP4) job document format (JDF) or similar job ticket formats.
