JDF

JDF, or Job Definition Format, is an XML-based standard developed by the International Cooperation for the Integration of Processes in Prepress, Printing and Packaging (CIP4). It is designed to describe and automate print production workflows by encoding a job’s requirements, processes, and resources in a machine-readable form. JDF aims to facilitate end-to-end automation across the production chain, from order intake and prepress through printing, finishing, and shipping, reducing manual data entry and improving interoperability among software and equipment.

The JDF data model covers elements such as a Job, which can be grouped into a JobSet; a JobTicket that captures constraints and requirements; and a hierarchy of Processes, Parts or Partitions, and Resources. ResourceLink elements describe how devices, software, fonts, inks, proofs, and other assets are allocated and used throughout the workflow. Communication between components often relies on the Job Messaging Format (JMF) or other transport mechanisms to exchange status updates and trigger subsequent steps.

JDF is used across multiple printing segments, including offset, digital, packaging, and label production, as well as finishing operations. It supports automation of tasks such as imposition, color management, trapping, and file transformations by providing a unified instruction set that can be consumed by various systems and devices.

XJDF is a newer, streamlined extension of JDF intended to simplify machine-to-machine exchanges while maintaining compatibility with existing JDF workflows. JDF remains in use in many shops and MIS/ERP and workflow software ecosystems, where it continues to enable integrated production planning and execution.
