XJDF (Exchange Job Definition Format) is a XML-based technical standard developed by the graphic arts industry to facilitate cross-vendor workflow implementations of the application domain. It is an XML format, providing job ticket, message description, and message interchange. XJDF development is managed by CIP4®[1] The CIP4 organization is a not-for-profit standards association, whose mission is to foster the adoption of process automation in the printing industry.

More than 120 organizations participate in XJDF development and implementations. They include member companies who manufacture equipment & technology for the production printing industry, integration services, and more than a dozen universities. In addition there are relationships with a number of adjacent standards organizations. [2][3] [4]

Why XJDF?. . . to enable workflow automation and interoperability in the commercial printing industry. Automated communication between pre-press, printing, finishing devices, and customers can substantially reduce setup times on equipment, waiting times between processes, and costs. While sourcing all equipment in a facility from a single manufacturer would simplify interoperability, it's uncommon, and in many instances impractical. The solution was for manufacturers of printing technology to coalesce around a pair of standards to accomplish that workflow automation: PDF, combined with XJDF. In 1999, four companies (Adobe, Agfa, Heidelberg, and ManRoland) created the CIP3 standards organization, and encouraged all interested manufacturers to participate in creating an XML-based interoperability language, which has evolved to become today's XJDF open-standard from CIP4.[5]

XJDF is an independent open-standard, but is also incorporated in an ISO PDF standard, which describes adding CIP4's XJDF metadata within a PDF file. PDF specifies the page image. Integration of XJDF "Intent" within an ISO-conforming PDF file's document part metadata can additionally specify: media to be printed on, binding method, simplex/duplex, folding, delivery address and more; all in a device independent manner. Within a [PDF/VT] file, XJDF may also specify variable elements.[6]

XJDF relationship to JDF[edit]

Both were developed by CIP4. In 2018, the newer Exchange Job Definition Format (XJDF) and its supporting XJMF messaging format were published. Due to evolving and more-demanding workflow requirements in the printing industry, a comprehensive redesign was required in the structure of JDF Job Definition Format, creating XJDF. However, both formats can be converted into each other and both formats (legacy JDF or modern XJDF) are often successfully deployed in parallel in the graphic arts industry.[7]

New development is primarily focused on XJDF, but continued maintenance of both versions of the specifications by CIP4 provides options to industry stakeholders wishing to implement XJDF, legacy JDF, or both into their product offerings and production environments.

Whereas JDF attempts to provide a model of an entire print production workflow including all interdependencies of processes and resources, XJDF is a pure interface format and the interdependencies are assumed to be tracked in an internal model of a controller or Management information system.
